Can an Air Purifier Cause a Sore Throat?

So, air purification is an important topic. 

Depending on where you live, it might even be important to your longevity. However, can air purifiers cause a sore throat?

The answer is, “That depends”.

If you go on Quora or any other online Q&A forums, you’ll find many people asking this exact question. 

It’s not uncommon for people to experience a sore throat, among other systems, and for their air purifier to look like the most likely culprit.

Reported Adverse Effects of Air Purifier Exposure

The anecdotal evidence that air purifiers make people sick is abundant. 

Many people complain of headaches and sore throats, alongside less common complaints of other issues.

The reality is that some types of air purifiers can cause harm.

Air Ionizers

According to the Mayo Clinic, some air purifiers can cause adverse effects. 

Specifically, air ionizer purifiers have been shown to produce several health problems:

  • Coughing
  • Throat irritation
  • Shortness of breath
  • Chest pain
  • Increased risk of respiratory infections

However, these effects are only reported from the use of ozone inhalation. Air ionizer air purifiers produce ozone to mask indoor odors. 

When inhaled, ozone can irritate the lungs, producing adverse effects, particularly in those with asthma.

Ozone is a naturally occurring gas important to Earth’s upper atmosphere. 

However, at ground level, it doesn’t produce a helpful result in terms of air pollution. In fact, at ground level, ozone is classified as an air pollutant.

Air ionizers release small amounts of ozone, but prolonged exposure, even to small amounts, can be irritating to the lungs. 

Air ionizers are not a healthy response to poor air quality. 

They are, however, proven to produce harmful gas.

When inhaled, ozone can cause multiple problems:

  • Throat soreness
  • Throat irritation
  • Lung irritation
  • Coughing

These occurrences are so common that ozone is probably the reason if you’ve heard rumors of air purifiers causing a sore throat or other problems.

How Much Ozone is Too Much?

Ozone in any amount won’t have a positive effect on your respiration. But the amount officially considered “dangerous” depends on the relevant regulatory bodies in your locality.

In California, the safety standard for ozone is that the air purifier should not produce more than 70 parts per billion during 8 hours.

Like many other localities’ regulations, California’s regulations are very specific.

There is no universal standard as to how much ozone is harmful.

Do All Air Purifiers Cause Respiratory Problems?

Actually, only some types of air purifiers aggravate the problems they are supposed to solve.

Some types of air purifiers work as intended and filter harmful elements out of the air. 

The most effective air filters you can use for this purpose are HEPA filter-based air purifiers.

HEPA Air Purifiers

High-Efficiency Particulate Air Delivery (HEPA) filters are also “mechanical filters.” 

They are the best option if you aim to remove the vast majority of pollutants 0.3 micrometers in size. 

In practice, that means that HEPA air purifiers will effectively filter out:

  • Dust
  • Pollen
  • Other allergens and pollutants

Of course, removing harmful pollutants and allergens from the air doesn’t necessarily mean you won’t experience discomfort.

Overall, certified HEPA air purifiers, when operating normally, are incredibly safe.

Can HEPA Air Purifiers Cause A Sore Throat?

HEPA air purifiers operating as intended will not cause a sore throat.

To ensure the air purifier is “operating as intended,” you must read the manual and maintain the air purifier as instructed.

The only case where a HEPA air purifier will not work or cause problems is when you do not use them for a long time.

When an air purifier is unused for an extended period, sometimes bacteria will form on the filter. 

Mold can also develop, leading to more direct and painful distress. 

Then, once you turn the purifier on, these germs will be released into the air and inhaled by everyone.

Despite the concern, this may cause you, the good news is that these problems are easily avoidable in HEPA air purifiers. 

You need to do a few things to make sure this doesn’t happen:

  • Change your air filter regularly, as instructed by the manufacturer
  • If you aren’t going to use your air purifier for a long time, remove the filter and store it safely

If you can follow those steps, a HEPA filter is almost sure to work as intended and improve your air quality.

What About Other Types of Air Purifiers?

We’ve already gone over the least harmful and most effective air purifiers. But there are a few other types:

  • Ultraviolet
  • Activated carbon (most use HEPA filters)
  • Electronic air cleaners (most use HEPA filters)
  • Air-to-air exchangers

Overall, no other type of air purifier is proven to cause any of the problems that air ionizers do. 

This is especially true of any kind that uses a HEPA filter.

What is the Difference Between a HEPA Purifier and a HEPA Filter?

“True HEPA” air purifiers meet the Department of Energy’s HEPA standards. They are superior to alternatives that use HEPA filters.

A HEPA filter is a pleated mechanical filter that meets the air quality measures set by the US Department of Energy. 

They are defined by their ability to capture 99.97% of airborne particles sized 0.3 microns. However, a “HEPA-type filter” only needs to remove 99% of such particles. These are known as the most penetrating particle size (MPPS). 

That means that they are capable of removing the following:

  • Pollen
  • Dust
  • Viruses
  • Bacteria
  • Mold
  • Any other airborne particles


Only a few kinds of air purifiers cause sore throats when misused. 

Most other air purifiers won’t cause sore throats or any other symptoms unless they aren’t properly maintained.

If you’re worried about the harmful effects air purifiers can cause, you should avoid ozone-emitting devices. 

True HEPA air purifiers are the most healthy and effective of all air purifiers. 

They should not cause any adverse health effects when appropriately maintained.

How to Clean a HEPA Filter

Nearly all air purifiers on the market feature a HEPA filter as part of the filtration system.

And unlike UV air purifiers, those with a HEPA filter must be cleaned regularly to function properly.

When I first bought my air purifier, I had no idea what a HEPA filter even was, never mind that I needed to clean it.

So, if you’re wondering how to clean the HEPA filter in your air purifier, you are in the right place.

In this guide, I will show you step-by-step how to clean a HEPA filter safely, so you can prolong the filter’s lifespan and use it for longer.

On top of that, I’ll go over how often you should clean your HEPA filter, the risks of doing it, and other relevant information I wish I had known back in the day.

Before going into any details, I want to familiarize you with HEPA filters.

What Is a HEPA Filter?

HEPA stands for High-efficiency Particulate Air.

A HEPA filter is a mechanical filter that consists of an amazing fiberglass mesh designed to capture 99.97% of solid particles as small as 0.3 microns.

0.3 microns in size is practically invisible to the eye, so you can imagine how fine the fiberglass mesh is to capture such solid particles.

In this size bracket, you’ll find particles such as dust, pollen, mold, bacteria, and other airborne particles in the air.

The size of particles your particular HEPA filter can capture will depend on the HEPA filter itself.

This is because HEPA filters come in ratings between 1 and 16, with 1 being the worst and 16 being the best.

I recommend against going for any HEPA filters below H13, as they won’t be as effective.

In other words, the lower your filter’s HEPA rating, the larger particles it will let slip through.

Why am I telling you all this?

It’s nice to know and essential when cleaning the HEPA filter itself.

The fiberglass mesh is so fine that any damage caused by your cleaning can render the filter useless.

And before we go into the next section, there’s one more thing I need to tell you about.

It’s how to spot fake versus authentic HEPA filters.

Since HEPA filters are extremely popular amongst consumers, you can expect there to be a lot of fakes on the market.

Such filters are not only a waste of money but might lead you to believe air purifiers are useless when the filter is at fault.

So, when shopping for a HEPA filter, ensure it’s a “true HEPA filter.”

These filters have passed all the standards necessary and are guaranteed to do the job.

Types of Cleanable HEPA Filters

There are two types of cleanable HEPA filters: washable and permanent.

If you don’t see any of these descriptors on the packaging or manual of your air purifier, then don’t clean your HEPA filters.

Instead, it would help if you replace the HEPA filters after a couple of months to keep your air purifier running correctly.

But if you have a washable or permanent HEPA filter, here are the steps you should follow.

Cleaning a Washable HEPA Filter

This type of HEPA filter is washable.

To clean a washable HEPA filter, all you need to do is run it under cold water.

All these filters need is a quick rinse every couple of months, which will work wonders for their lifespan.

When doing this, avoid any cleaning agents you think might help.

Scrubbing or brushing the HEPA filter can significantly damage it as it can destroy the delicate fiberglass mesh used to capture different particles.

Once you’re done rinsing it, you must leave it out to dry before reinstalling it in the air purifier.

That’s all it takes to wash these filters, but you have to ensure it’s dry before reinstalling them.

You risk damaging the machine if you put it back in the air purifier when it’s wet.

Mold and mildew will develop inside the air purifier, which isn’t something you want.

If the weather is warm, 48 hours should be plenty; if not, leave it out for a few days until you’re confident it’s thoroughly dry.

Cleaning a Permanent HEPA Filter

You can only clean your HEPA filter with water if it explicitly states it’s washable.

If you have a permanent HEPA filter, you can also clean it, but you should not use water.

If you use water on these filters, you risk doing irreversible damage to the filter.

Instead, you should clean these filters carefully using a vacuum with a soft brush.

To clean a permanent HEPA filter, remove any significant chunks of dirt you can see using the vacuum.

Remember, these filters capture dirt and dust, so a little build-up is fine.

When cleaning a permanent HEPA filter, your goal should only be removing large dust clumps, as getting deep into the filter could damage the mesh.

This is also why you need to replace your HEPA filter with a new one after a few cleans.

How to Tell if I Should Clean or Replace My HEPA Filter

For best results, it’s always good to completely replace your HEPA after you’ve used it for 8-12 months.

If you have an air purifier for pets, and your furry animals shed a lot of fur, you should do it more often.

However, that’s unnecessary in most cases, as you can clean the filter and prolong its lifespan.

Determining whether your HEPA filter can do with one more clean before replacing it can be a tough call for the untrained eye.

There are two things to consider when making this decision.

You want to consider how long the filter has been used and how many times you’ve cleaned it already.

If you’ve cleaned the filter several times and have had the purifier for over a year, it’s safe to assume it’s time for a replacement filter.

How to Clean a HEPA Filter Safely and Effectively

There are definite risks that come with cleaning a HEPA filter, even if you have a washable or permanent model.

That said, there are still many benefits to cleaning your HEPA filter regularly, especially if you aren’t keen on replacing the filter every 6 months.

So, if you plan on cleaning your HEPA filter, the least you can do is ensure that you’re doing so safely.

I’ll go through some tips to remember when cleaning your HEPA filter to ensure that you are as safe as possible when cleaning your air purifier HEPA filter.

Take Your Air Purifier Outside

If the weather allows, there’s no better place to clean your HEPA filter than outside.

This is because the second you open your unit, dust, pollen, and other solid particles will start to fly out of it.

And if you’re inside, all the particles the unit has captured up to this date will end up in your indoor air, get stuck in the carpet, or cover surfaces nearby.

If that were to happen, it would have defeated the whole purpose of running your air purifier all that time.

Clear the Room (If Cleaning the Filter Inside)

While I highly suggest cleaning your HEPA filter outside, there are times when you have no choice but to clean it indoors.

When doing this, it’s best to make sure that the only person in the room is the one who will clean the air purifier.

That way, no one else is at unnecessary risk of inhaling harmful particles.

If there are people at home with respiratory conditions, they are the least viable to clean the filter.

So, I suggest asking anyone with respiratory conditions to exit the room when you clean the HEPA filter to keep the risks as low as possible.

Wear Gloves and a Mask

The last tip I can give you is to wear the appropriate protective gear when cleaning your HEPA filter.

When you do this, ensure that you don’t inhale or come into contact with harmful particles when cleaning the filter.

The best protective equipment to wear when cleaning a HEPA filter is gloves and a mask.

But if you can, I suggest wearing goggles, as getting dust and other harmful particles in your eyes are far from ideal.

Take Out the HEPA Filter

Once you’ve established a place where you’re going to clean the HEPA filter and have all the equipment ready, it’s time to take apart the air purifier.

The first thing you need to do is make sure it is off and unplugged from any power source.

Next up, you need to open up the casing of your air purifier.

This process can vary from model to model and brand to brand, so check out the user manual for more instructions.

I use the Levoit 300S, and all I have to do to access the filter is to rotate the unit’s base to the left until it opens up.

Once you’ve opened the casing, find and remove the HEPA filter.

Use a Vacuum Cleaner

Once out of the casing, a vacuum cleaner is the only way to clean it if you have a permanent HEPA filter.

Ideally, you want to use the gentlest setting on your vacuum cleaner and avoid using attachments that can damage the filter.

Additionally, it’s best to use a vacuum cleaner with a HEPA filter so the harmful particles won’t end up floating around the air.

And if you own a permanent HEPA filter without a vacuum, consider cleaning it every now and then.

You should only clean permanent HEPA filters with a vacuum cleaner. 

If you don’t have one, you’re better off not cleaning it and just replacing it as necessary.

Are All HEPA Filters Cleaned the Same Way?

Generally speaking, yes, all HEPA filters are cleaned the same way.

This is because no matter how big or small, at the end of the day, they are the same, just different in size.

So, practice the advice I provided you above when cleaning your particular HEPA filter, and you should be fine.

And if you encounter any trouble, refer to your unit’s user manual or watch a video on YouTube.

That’s what I did when I had to clean my HEPA filter for the first time all those years ago.

How Often Should a HEPA Filter Be Cleaned?

As per the recommendations of experts, I use my air purifier 24/7.

And as a result of that, my air purifier will collect much more particles compared to someone using their unit for just 8 hours a day.

So, when it comes to the regularity between which you need to clean your HEPA filter, there are three things you need to consider.

How often you use your air purifier, how polluted the air in your area is, and how big your air purifier’s HEPA filter actually is.

The more often you use your unit, the more polluted your area is, and the smaller the HEPA filter, the more you need to clean it.

To give you a rule of thumb, I clean my HEPA filter every 2-4 weeks, use my unit all the time, and live in the city center in one of the biggest cities in the country.

How Many Times Can I Clean My HEPA Filter Before Replacing?

It’s not recommended that you clean your HEPA filter because you can’t clean it as well as needed to make it as clean as new.

Instead, manufacturers suggest that you replace your HEPA filter every 8-12 months.

With that in mind, as someone who wants to maximize their money, I decided to clean the HEPA filter myself and prolong its lifetime by at least another 50%.

And to be honest, it worked.

After taking proper and regular care of my HEPA filter, I replace my HEPA filter every 14-16 months.

Regarding the cleaning-to-changing ratio, that depends on how often you use your unit.

Risks to Cleaning a HEPA Filter

Even if there are certain HEPA filters that you can clean to extend their lifespan, it might not be the best idea.

I still recommend cleaning these filters every now and then so you won’t have to replace them often.

But before doing so, I suggest learning about the different risks and what you can do to mitigate them when cleaning your HEPA filter below.

You Might Damage the Filter

The most significant risk that you want to consider when using a HEPA filter is the damage you might cause to the actual filter.

Let me explain why.

As mentioned earlier, HEPA filters consist of a fine fiberglass mesh that captures tiny particles.

And when I say fine mesh, I mean it.

The mesh on the HEPA filters used for air purifiers is usually small enough to capture particles as small as 0.3 microns.

That means that the fiberglass mesh is very delicate.

When you clean your HEPA filter, you must be as gentle as possible, as even a light force can tear and damage the mesh.

Once you damage the mesh on a HEPA filter, larger particles can start escaping through the filter, so your air purifier won’t capture particles as effectively as before.

While this doesn’t mean that you shouldn’t clean permanent or washable HEPA filters, it does mean that you have to take extra care when doing so.

You Will Release Harmful Airborne Particles 

When you clean the HEPA filter of your air purifier, you have to open up the appliance to reach the filter.

Opening an air purifier risks releasing all the dust and harmful airborne particles it has already captured into the air.

And while the dust that comes from the pre-filter isn’t something you should worry about, the dust inside the HEPA filter is much finer and hard to see.

When you remove the HEPA filter from your air purifier, you risk inhaling all the trapped particles.

This can be very dangerous, especially if you struggle with allergies and other respiratory conditions.

If you must clean your HEPA filter, I recommend doing so outdoors.

That way, the harmful particles trapped inside the filter are dispersed into the air.

If you do this indoors, the dust and other particles might circulate around the room or get on different surfaces.

This completely defeats the purpose of using an air purifier.

It’s also one of the reasons why some people don’t recommend cleaning your HEPA filter at all and just replacing it every 6-8 months.

Another thing you can do when cleaning your HEPA filter is to make sure you’re wearing a face mask and other PPE.

That way, any dust particles that try to enter your lungs won’t be able to, keeping you as safe as possible.

You Need a HEPA Filter to Clean a HEPA Filter

If you have a washable HEPA filter, this won’t be that much of an issue, as you can rinse the filter under cold water to clean it.

However, if you have a permanent HEPA filter, you can’t use just any vacuum to clean it up.

If your vacuum cleaner doesn’t have a HEPA filter, the whole cleaning process is pointless.

Cleaning a HEPA filter with a vacuum without a HEPA filter means various particles are released back into the air.

Vacuum cleaners with HEPA filters can capture dust particles and ensure they stay inside the bag or dust container.

That way, you can remove all the dust build-ups in your HEPA filter without worrying about the particles entering indoors.

What Happens If You Don’t Clean Your HEPA Filter?

The consequences of not cleaning your air purifier can be severe both for the filter and the appliance.

When I first bought my air purifier, I didn’t clean the HEPA filter for nearly 3 months until I found out it’s something I need to do much more often.

The results weren’t as devastating, but the filter was extremely clogged up, and I could tell the air purifier was struggling.

This is because when the filter clogs up with particles, it will have difficulty pushing the clean air past the filter, causing the unit to work harder.

If you don’t clean your HEPA filter, you’ll impact the effectiveness of your air purifier.

On top of that, you also risk tearing the filter or damaging the motor, at which point, you might as well buy a new air purifier.

So, to get the most out of your unit, keep an eye on it and conduct regular maintenance.

How To Clean A HEPA Filter: Conclusion

Cleaning your HEPA filter regularly is a fantastic way to ensure it serves its purpose for longer than intended.

For best results, clean your HEPA filter every 2-4 weeks, depending on how regularly you use your air purifier.

That said, keep in mind that only some HEPA filters can be cleaned, and you have to take care when cleaning them to ensure you don’t damage the filter.

So, before you open up your air purifier to clean the filter, make sure that you check whether or not the filter is cleanable.

Then when you finally get to cleaning the filter, make sure to follow my tips above to ensure you do it effectively and safely.

How to Clean Your Levoit Air Purifier

Levoit is one of the top brands of air purification appliances on the market today.

The brand is so reliable and creates excellent air purifiers that I needed a little convincing to get one myself (I own the Levoit 300s).

I immediately put it to use the door the second I got my unit through the door.

Within hours, it made a massive difference to my quality of life by cleaning the air from all irritants that typically trigger my asthma.

After some weeks, I knew it was time to clean it, but I had yet to learn how.

White Dust from Air Purifier – What Is It and How to Remove It?

I bought my air purifier because I was suffering from severe allergies and wanted all irritants in the air gone.

And while my air purifier did a fantastic job, not long after, I noticed that my air purifier was releasing white dust, or at least that’s what I thought.

In the beginning, I was shocked just as much as I was confused.

Nobody told me I could expect white dust to come out of my unit; frankly, I didn’t either.

I was scared that I might have damaged my unit or that it might be releasing toxic waste that I didn’t know about.

That made me quickly search around to see what other people had to say about white dust coming out of an air purifier.

And if you’re in a similar boat to when I was just a few months ago, you’re in the right place.

In this article, I’ll go over why your air purifier releases white dust and what you can do to stop it.

But, before I do any of that, I first want to put you at ease by telling you what white dust is and if it’s dangerous or not.

What Is White Dust?

White dust is the byproduct of certain air purifiers, which is why you may see it around your home or the air purifier itself.

White dust is often a good sign because the unit works as intended.

The dust is the dried-up leftover mineral content in the water often used in dehumidifiers and water-based air purifiers.

In other cases, white dust can be actual dust from your basement, evidence of a carbon monoxide leak, or other events.

But is white dust something to worry about?

In the following section, I’ll get into more detail about the safety surrounding white dust.

Is the White Dust Dangerous?

One thing I was thrilled to learn when researching the cause of white dust around my air purifier was that white dust usually isn’t dangerous.

Generally, white dust from humidifiers or water-based air purifiers is harmless to humans and pets.

So, the main concern is that it can make your house and various surfaces appear dirty or dusty, but that’s about it.

Since the white dust is usually a result of excess mineral deposits from the water you use in your appliances, you don’t have to worry about them.

The minerals that end up as white dust are likely also present in our drinking water and are entirely safe.

That said, if you notice white dust around your home and aren’t sure if it’s 100% your air purifier, it could be coming from your vents.

In such a case, it could be a result of a carbon monoxide leak, which is a situation that requires immediate attention.

Why Is There White Dust Coming From My Air Purifier?

Sometimes, the white dust can come directly from the air purifier.

This is only the case if you have a water-based air purifier loaded with hard water.

Loading hard water with many minerals in these air purifiers can release some minerals into the air.

And once these minerals dry up, the byproduct you will find around the unit, and your home is white dust.

But if you don’t have a water-based air purifier, the white dust likely isn’t coming from this appliance.

I know this because I don’t own a water-based air purifier, yet I had white dust in my home.

You’ll find white dust around your home for many reasons, and I’ll explain them in the following section.

You Use an Ultrasonic Humidifier

First, using an ultrasonic humidifier, you might find white dust in your home.

These humidifiers balance the humidity levels indoors by releasing moisture into the air.

This can be helpful during the winter months when the air starts to dry.

Suppose the water you load into the humidifier is packed with minerals.

In that case, the humidifier will release minerals along with water vapor.

And while the water vapor makes its way into the air, the mineral deposits eventually fall onto different surfaces, which is the cause of white dust.

This is especially true if you use hard water in your humidifier, which refers to water packed with various minerals.

This isn’t necessarily bad, but you’ll have to do more cleaning than usual.

So, if you have an ultrasonic humidifier at home, that’s one of the biggest reasons behind white dust.

The Dust Is Coming from Your HVAC System

If you’re unsure that the dust is coming from your air purifier, check if you have a centralized HVAC system at home.

If you do, then that can be another source of white dust.

HVAC systems use an intricate network of vents around the house to give you complete control over indoor air conditions.

These systems are great for heating and cooling entire homes without buying multiple appliances.

However, there may be gaps in the ducts and vents that allow dust from the basement and other rooms to enter the HVAC system.

And when the HVAC unit releases air into different rooms, that dust might come with it.

I suggest getting an in-duct air purifier IF you have an HVAC system to prevent this.

Or, you can use air purifiers in different rooms in the house to capture this white dust and prevent it from getting into your respiratory system.

Chemical Reaction in Your Furnace

If you have a furnace at home, there could be a chemical reaction involving zinc, galvanized steel, and the furnace exhaust.

This reaction results from white dust, which you might find on different surfaces in your home.

If this is the case, you should clean the furnace properly and keep an air purifier on in the home so it captures the dust immediately.

Mass Use of Paper Products at Home

This probably won’t be the primary cause of white dust at home, but it’s something I came across on a forum during my research.

Using paper products like notebooks, sticky pads, tissues, and other similar items could add to the white dust at home.

Whenever you rip up tissue or paper, it produces fuzzies that enter the air.

Most of the time, you won’t notice these fuzzies, and your air purifier should capture them right away.

But sometimes, the fuzzies can build up over time and stick to different surfaces at home, which you might see as the white dust we’re talking about.

White Dust Coming Out of the Air Vents

When I read about the different causes of white dust at home, I figured that my air purifier wasn’t the culprit.

Since I used a HEPA air purifier, I knew it wasn’t the cause of the white dust I find on various surfaces at home.

That’s when I decided to look at the air vents of my HVAC unit.

And when checking it out, I learned that the white dust was coming from my air vents.

This is a problem that many people encounter with HVAC systems, and many things can cause it.

If you have a new HVAC system, the white dust could be remnants of oil and film in the vents.

This is relatively harmless and disappears after a while.

But if your HVAC unit isn’t new, there could be other issues.

To start, white dust from your vents could indicate a carbon monoxide leak, which is very serious and something you need to address immediately.

Granted, this isn’t that common, but it’s essential to keep it in mind and check if you see white dust coming out of your vents.

Another reason that white dust could leak out of the vents is because of the humidifier present in some HVAC units.

As mentioned earlier, if you use hard water for your humidifiers, you might find mineral deposits on various surfaces at home which look like white dust.

And if you live near the coast, the white dust could be caused by the high salt content in the air.

There are many ways to fix the issue of white dust coming from your HVAC unit.

If the HVAC unit is new, you must wait for the leftover oil and film in the vents to be released.

For old HVAC systems, you can prevent white dust by ensuring the unit is always clean and well-maintained.

And to add an extra layer of protection, you can also use an air purifier to capture the white dust before you breathe it in.

How to Get Rid of White Dust at Home

Until you resolve the cause of white dust, the best way to get rid of it is to wipe down your surfaces with a dampened cloth.

The best way to resolve the issue with the white dust from your air purifier is to start using soft water or water that doesn’t contain as many minerals.

Most of the time, tap water has a high mineral content, so you might want to switch to distilled purified water to eliminate white dust at home.

So, I highly suggest putting soft water in your humidifier or air purifier, as it’s the easiest way to eliminate white dust.

Another effective measure you can take is using a demineralization cartridge.

Most modern humidifiers and water-based air purifiers have a slot where you can put the cartridge.

When you do this, you will filter out white dust and other mineral deposits before they leave the appliance.

But suppose the above techniques aren’t ideal for you.

In that case, consider switching out your air purifier and humidifier.

For example, use a HEPA air purifier. You will never have to deal with white dust as these devices cannot produce it.

But at the end of the day, white dust isn’t dangerous to humans, so if you notice it at home, you should have no reason to panic.

Making Sure Your Air Purifier Eliminates White Dust

Your air purifier likely isn’t the cause of the white dust around your home.

But did you know that you can use your air purifier to ensure you don’t deal with white dust?

Remember, air purifiers are designed to filter out particles like dust from the air and keep them from getting into different surfaces and away from your lungs.

To ensure your air purifier effectively eliminates white dust, you must place it in the right spot.

Air purifier placement is crucial if you want the device to function correctly.

Ideally, you want to place the air purifier in the middle of the room or in an area with the best airflow.

When you do this, you ensure that most of the air in the room passes through the air purifier so it captures white dust and all other particles.

Additionally, elevate the air purifier slightly and ensure no obstructions.

If you don’t have much space in your room and need to place your air purifier next to a wall, feel free to read my guide to get the best results.

Lastly, ensure you get the right air purifier for the room.

If you have a large room, you need an air purifier with the power to match.

That way, it captures all the room particles, including white dust from other appliances.


If you just bought an air purifier and noticed white dust around your home, chances are that the air purifier isn’t the reason for the dust.

Most of the time, the white dust comes from ultrasonic humidifiers, HVAC systems, and other appliances in your home.

But if you see white dust in your home, you don’t have to panic as the dust is safe for humans and pets.

If you use your air purifier properly, you won’t have to deal with white dust as much.

So, ensure that you place your air purifier in the appropriate spot and have the right air purifier for the room.

And you won’t have to deal with white dust at home often when you do that.

Red Light on My Levoit Air Purifier: Meaning

I’ve owned the Levoit 300S for over 4+ years, and I’ve never had any problems with it.

It made a difference in my life as I no longer suffer from seasonal allergies as I did before owning it.

However, about 10 months into owning it, a red light started to flash, quickly worrying me.

The last thing I wanted was for my air purifier to have broken or not to operate properly.

I needed clarification about what this red light meant, especially since it seemed like my air purifier was working like it usually does.

That’s when I started asking around in my friend group and going as far as speaking to strangers on the internet about it.

Now that I know what the red light on my Levoit air purifier means, I’ll tell you everything you need to know about it in this article.

What Does the Red Light on My Levoit Air Purifier Mean?

If you see the red light on your Levoit air purifier blinking after a couple of months, it’s no reason to panic.

The red light on most Levoit air purifiers indicates that it’s time to check on the filtration system.

This means that the filter can stay the same.

It could be because the filter is starting to clog up, or it may have been misplaced.

Whatever the case, checking out the filter as soon as the red light blinks is essential.

This is important because all Levoit air purifiers rely on their filters to clean the air.

Most Levoit air purifiers have a pre-filter, HEPA, and carbon filter.

These are all designed for different tasks, but they all work together to clean the air.

That said, the filters can get clogged after some time and require cleaning or replacing.

When the filters are clogged, it affects the air purifier’s ability to capture particles, resulting in poorly purified air.

This is why the red light on Levoit air purifiers usually turns on after a couple of months or years of use.

That said, the lifespan of the filters on your air purifier depends on several factors.

Some people might get the light flashing after 6 months, while others can get it after 18 months.

To start, if you have poor air quality at home, this could lead to the filters capturing more particles, so they will wear out sooner.

Additionally, you always keep the air purifier on 24/7 (which I highly recommend).

In that case, you will need to change or clean the filters more often.

But what are you supposed to do when the red light on your Levoit air purifier starts blinking?

As I said earlier, you shouldn’t panic when this happens, as you can quickly correct the issue in a few minutes.

What to Do If There’s a Red Light Blinking on Your Levoit Air Purifier

Suppose you own a Levoit air purifier and use it regularly. 

In that case, the red light will definitely start blinking after a while.

This red light is designed to remind the owner to check the filter and clean or replace it as it’s starting to clog up.

When my air purifier started blinking, I began to panic a little.

But when I went online to look for help, I found the solution was straightforward.

So, here’s what you need to do if you notice the red light on your Levoit air purifier is blinking.

Check the Filter

The red light on your air purifier is a check filter light that reminds owners to look at their filters from time to time.

So, if you notice that the red light is blinking, you first need to check the filter.

From there, you can assess if it’s time for a cleaning or replacement.

Remember, the pre-filter is the only filter you can clean on most Levoit air purifiers like the Core 300s.

Unlike other air purifiers, Levoit models don’t have washable HEPA filters.

So if you notice that the HEPA or carbon filter is used up, you will have to replace it.

Once you’re done checking the filter, you can either put it back in if it’s still clean, clean the pre-filter if necessary, or replace the HEPA and carbon filters if they’re used up.

In the following sections, I’ll explain how you can do all of those things.

Cleaning the Filter

If it’s your first time seeing the red light on your Levoit air purifier blinking, you probably won’t need to change the filters.

The first thing you need to do is clean the pre-filter.

To do this, you need to clear the room and wear a mask since you’re at risk of inhaling dust when cleaning the filter.

The only thing you need to clean the pre-filter on your Levoit air purifier is a vacuum cleaner with a soft brush.

From there, vacuum up the dust and other particles you see on the filter until all of it is removed.

Once finished, put the filter back in, and your air purifier should usually work.

This also means that the red light that was bothering you should now be gone.

If it’s been 6-8 months since you first started using the air purifier, you might need to replace the filters.

Replace the Filter (If Needed)

After some time, you will have to replace your air purifier’s HEPA and activated carbon filter.

What I like about Levoit air purifiers is how easy the filters are to replace.

They often come pre-packaged, and all you have to do is pop the new filter instead of the old one.

Changing the filters on a Levoit air purifier may also vary depending on your model.

This is why it’s best to refer to the manual before changing the filters to ensure you’re doing everything correctly.

There are also plenty of videos on platforms like YouTube where people show you how to change the filter on your particular model.

Reset the Indicator

After changing the filter or cleaning it, you have to reset the indicator to ensure that the light stays off until it’s time to recheck the filter in the future.

To do this, you must hold the button until the red light turns on.

When the light turns on, please press the button for another three seconds until it turns off.

Once the light is off, the indicator has been reset, and you can return to using the air purifier.

Note that every air purifier has a slightly different design, so check the manual for further instructions on your specific model.


Seeing a red light on your Levoit air purifier can be concerning, but there’s no reason to panic.

All this means is that the air purifier’s filters need to be checked, which you can accomplish in just a few minutes.

If you see that the pre-filter is dirty, you can vacuum it up to clean it.

And suppose it’s been between 6-8 months of using the air purifier.

In that case, you will have to replace the filters to ensure the air purifier is working properly.

Once you do that, you must reset the indicator, and your air purifier should work just as well as it did when you first bought it.

Are UV Air Purifiers Safe?

When I decided to buy myself an air purifier, I was surprised at the sheer number of different air purifiers available on the market.

But one type of air purifier that stood out from the pack when I was shopping was the UV air purifier.

I was familiar with using UV light to disinfect and cleanse the air.

Still, I had no idea that the technology was also being added to everyday air purifiers.

That said, I was concerned about the safety of these air purifiers.

I was already familiar with the fact that some ionic air purifiers can produce ozone, which is why it’s best to stay away from them.

So, I wondered if UV air purifiers had a similar effect and if I was better off not spending any money on such an appliance.

That’s when I researched and found out a fair amount about UV air purifiers.

And in this article, I’ll go over everything I know about the safety of using UV air purifiers in your home.

What Are UV Air Purifiers?

As the name suggests, UV air purifiers are air purifiers that also use UV light to clean the air.

Some air purifiers rely solely on UV lights for purification, like in-duct models.

In contrast, others use UV light as an additional cleanser on top of their existing filtration system.

Regardless of which one you go for, they all work the same.

These air purifiers use UV lights to clean the air, which is excellent for disinfecting and removing harmful particles from the air.

These air purifiers are popular because they target particles that other air purifiers might miss.

For example, most portable air purifiers that don’t have UV lights only use HEPA or carbon filtration to clean the air.

The filters on most air purifiers are great for capturing small particles like dust and pollen while absorbing harmful VOCs and other gaseous particles in the air.

While this is great and makes a huge difference in air quality, these air purifiers don’t target or eliminate viruses and bacteria.

So, UV air purifiers are ideal for people who want to breathe in safer air at home that doesn’t contain viruses and bacteria that can cause disease.

But how do UV lights eliminate bacteria in the first place?

Well, I’ll explain that in full detail in the next section so you can wrap your head around how these air purifiers work.

How Does UV Light Cleanse the Air?

UV lights clean the air in the same way sunlight does.

If you’ve ever sunned your pillows to clean them, you’re already familiar with how UV lights.

When you use UV-light air purifiers, the device emits a UV-C light, which doesn’t naturally enter our atmosphere.

Since these lights aren’t naturally present on Earth, most organisms have no natural defenses against them.

As a result, exposure to UV light can successfully eliminate many viruses and bacteria in the air.

UV-C lights are such effective cleansers that we aren’t just using them for the air.

In fact, people use UVC lights to clean water and even eliminate harmful pathogens from specific surfaces that have been exposed.

There are different types of UV-C air purifiers on the market, and each works slightly differently when cleaning the air.

To start, let’s look at the in-duct UV air purifiers.

These air purifiers are installed into an HVAC system and emit a UV light that the air has to pass through before being released back into your room.

This causes airborne pathogens and bacteria to die before they float around the air and enter our lungs.

Portable UV-C air purifiers work in a very similar fashion.

However, instead of shining the light inside the vents, these air purifiers shine a UV-C light in the room.

Typically, these air purifiers have multiple filtration systems working simultaneously.

For example, while the HEPA and carbon filter deal with solid and gaseous particles, UV-C light takes care of viruses and bacteria in the air.

Are UV Air Purifiers Safe?

I wrongfully equated UV air purifiers as the same thing as ionizer air purifiers, which I recommend staying away from at all costs.

This is because ionizers, while they are excellent at eliminating particles from the air, create ozone as a by-product of the cleansing process.

This can be very dangerous as ozone can cause many problems if you breathe in too much.

And even if ionizers produce small amounts of ozone, it’s best to stay on the safe side and avoid them in general.

But can I say the same about UV air purifiers?

Luckily, UV air purifiers don’t produce as much ozone as ionizers, which makes them inherently safer than ionizers right away.

However, consider that UV lights can still produce ozone when reacting with particles.

That said, you don’t have to worry about exposure to the light itself doing any harm.

Humans usually don’t react negatively to UV light, though I don’t recommend looking directly at the light.

But since these air purifiers produce small amounts of ozone, you might want to turn off the UV light occasionally, especially when in the room.

That said, UV air purifiers are generally very safe appliances for people looking to cleanse the air at home.

You can use these air purifiers to effectively clean the air in an indoor space, keeping your respiratory system safe from harmful viruses and bacteria.

Types of UV Air Purifiers

As I mentioned earlier, shopping for UV air purifiers can be difficult because there are many types to pick from.

And while it might seem complicated at first, I quickly learned that most UV air purifiers fall into one of two categories.

So, let’s look at these different categories to better understand which UV air purifier would be the best option for your needs.

In-Duct UV Air Purifiers

The first type of UV air purifier is an in-duct system.

As you might guess, you have to hire professionals to install these air purifiers in your HVAC system.

These air purifiers emit a UVC light in the vents of your HVAC system, so all the air that comes out of the vents is clean and free of harmful pathogens.

On top of that, these air purifiers are built into your HVAC system, so it cleanses all the indoor air right away.

While these air purifiers might be more expensive, remember that you’ll only need one air purifier for the entire house.

This can be way more convenient than portable air purifiers that you have to move from room to room.

So, these air purifiers may offer significantly more value than your typical portable air purifier.

That said, portable air purifiers with UV lights can still be helpful and could be just what you need.

But to give you a better idea if they’re for you, I’ll discuss these air purifiers in more detail in the next section.

Portable Air Purifiers

As the name suggests, these are air purifiers that you’re supposed to move around the house on demand.

When you think of modern air purifiers, these are probably the ones that come to mind, as they are way more common than an HVAC air purifier.

These air purifiers use both filtration and UVC lights to cleanse the air.

So, aside from emitting a UVC light to eliminate specific pathogens and viruses, the machine uses various filters to capture different particles floating around the air.

This is why portable air purifiers might be the more practical option for many people.

The downside to portable air purifiers is that they are designed for smaller spaces.

You won’t be able to find a portable air purifier that can handle an entire home.

Instead, you’ll have to move the air purifier around or buy multiple models to clean the air at home.

Even if you get a bit more protection from portable air purifiers, they can only protect you in the room where they are in.

With that said, both types of UV air purifiers can significantly protect your respiratory system.

However, deciding on an air purifier that best fits your needs is essential before going on the market and checking out the different options available to you.

How to Find the Best UV Air Purifiers

The first thing you need to do when considering a UV air purifier is to determine if you want an in-duct system or a portable air purifier.

Each comes with its own benefits, and it’s up to you to figure out which one better suits your needs.

But even if you choose a specific type of UV air purifier, you’ll still be faced with many options when shopping.

So, here are other things to keep in mind when buying a UV air purifier to make the entire shopping process much more manageable.

Consider the CADR

When buying an air purifier, it’s essential to consider the CADR or clean air delivery rate.

This basically refers to the air purifier’s ability to clean the air.

Ideally, you want an air purifier with a CADR that’s at least 2/3s of the total room size.

For example, if you have a room that’s 300 square feet, you will need an air purifier with a CADR of at least 200.

If you buy an in-duct purifier, you won’t have to worry about CADR.

Still, it’s essential when buying a portable air purifier.

With that in mind, you should measure the area of the room where you plan on placing the air purifier before buying one.

That way, finding the right air purifier for your needs will be much easier.

Look for a Good Filtration System

The next thing to consider is the filtration system.

As I mentioned earlier, most portable UV air purifiers have a filtration system that works with UVC light.

For the best results, I recommend getting an air purifier with a carbon filter and HEPA filter.

These air purifiers use HEPA filters to capture solid particles in the air, like dust, pollen, and similarly-sized pollutants.

On the other hand, the carbon filter absorbs harmful gases like smoke, VOCs, and even strong odors that may be annoying to deal with.

Consider the Unit’s Efficiency

If you want to make the most out of your air purifier, keep it on as much as possible.

Ideally, your air purifier should be on 24/7.

But if you want to always leave your air purifier on, you need to get an energy-efficient model.

So, check out the air purifier’s power consumption and ensure the machine doesn’t use more power than it needs to clean the air.

Are UV Air Purifiers Safe? Conclusion

If you’re considering buying a UV air purifier, I wouldn’t tell you not to because they’re great.

Despite a widespread belief that UV air purifiers can be dangerous, they aren’t.

I’ve owned mine for over 5+ years and have had zero complaints.

However, there is one concern you would want to keep in mind, and that’s the fact that UV air purifiers produce small amounts of ozone.

But besides that, you can’t go wrong with either if you buy a unit with only a UV light or one that uses UV on top of an existing filtration system.

Are Ceramic Space Heaters Better?

One of the ways I made sure that my house was ready for winter was by buying a space heater.

That way, I won’t have to worry about feeling cold and uncomfortable in my home.

But when I went on the market to buy a space heater, I was quickly confused by all the options available.

And when researching which space heater was the best, I found that most people recommended I get a ceramic space heater.

With all these people recommending ceramic space heaters, I started to wonder if they really were the best space heaters available.

Having owned a ceramic space heater for over two years now, in this article, I’ll tell you everything you need to know about them.

I’ll detail how it compares to other types of space heaters and whether I recommend getting one for yourself.

But before I do any of that, let’s first look at what a ceramic space heater is.

What Is a Ceramic Space Heater?

Ceramic space heaters are one of the most common types of space heaters on the market today.

This might not sound very clear, but ceramic space heaters aren’t actually made from ceramic.

Most of the components in these heaters are made of plastic, which is strange considering it’s a heater, after all.

However, the actual heating element of these heaters is made of ceramic and is called a positive temperature coefficient (PTC) ceramic heating element.

These heaters use electricity to heat the PTC heating element, which then conducts heat, warming up any air that flows through the heater.

Since the heating element is made of ceramic, it’s very durable and built to last the test of time.

So, you can expect ceramic space heaters to last a long time and efficiently heat your home for years.

That said, are these space heaters really the best option for shoppers?

To figure that out, you first need to understand the different types of space heaters available on the market.

I’ll get into that in the next section.

The Different Types of Space Heaters

You’ll be surprised by the sheer variety of space heater products available to customers.

Aside from ceramic heaters, there are five other space heaters you might encounter when shopping.

So, let’s look at these heaters to understand why most recommend getting a ceramic space heater over other options.

Fan Heater

This is probably the second-most popular space heater you’ll find.

These heaters work very similarly to ceramic space heaters, the only difference being that these heaters don’t use a ceramic heating element.

Instead, the heaters use metal coils, which heat up through electricity.

Then, the heater will use a fan to blow air over the hot coils, which raises the temperature.

These heaters are great for small spaces and for people on a budget.

I own an all-in-one heater, dehumidifier, and air purifier, which works the same way.

However, these heaters aren’t the most efficient and are only suitable for heating up small areas.

On top of that, these heaters don’t give you that much temperature control.

So, if you want to heat a larger space more efficiently, avoid fan heaters.

Infrared Space Heaters

Infrared space heaters are unique.

Instead of using a fan and heating up the air, these heaters send electromagnetic waves.

These waves will then heat up objects in the room, raising the temperature indoors.

That said, some infrared heaters also come with a fan.

That way, the room will be heated at a much faster pace.

While these heaters are great, they do come with a downside.

Most of the time, these heaters are heavy and only send heat in one direction.

Oil-Filled Space Heaters

As you can tell by the name, these space heaters are filled with oil, which the heaters use to raise the room’s temperature.

These heaters are sometimes called radiator heaters as they bare a resemblance to the old-school radiator heaters you can find in some homes.

These heaters are filled with oil, which they heat up using electricity.

The heater then pushes the heated oil through the fins of the heater, and when the fins get hot, they release heat into the air.

So, this is another type of heater that doesn’t blow hot air but instead radiates heat.

The heaters cannot use fans to raise the room’s temperature and only rely on heat radiation.

The most significant benefit of these heaters is that they stay hot even when turned off, so you don’t have to constantly keep them on to produce heat.

Additionally, most modern oil-filled space heaters come with a digital thermostat, which gives you complete control over the temperature.

These reasonably heavy heaters get very hot, so you may have difficulty moving them around.

But it’s a great option if you don’t want to use a ceramic or a fan heater.

Panel Space Heaters

Panel space heaters are a relatively new invention starting to gain traction amongst customers.

These heaters are similar to oil-filled heaters as they don’t require or use a fan to raise the temperature indoors.

As you might guess, these heaters have panels that heat up through electricity.

From there, the panels radiate heat to warm up the room.

Panel space heaters are so popular because of their modern look.

On top of that, you can mount the space heater on the wall or make it stand on its own, giving you a lot of flexibility.

These are one of the safest heaters available as they don’t have as high a risk of fires as oil-filled space heaters.

With that being said, these heaters aren’t the best at warming up the room.

Most people say that these heaters don’t exactly warm the room, but they remove the chilly feeling that comes with cool air.

So, these heaters are the most effective when used as a supplemental heating unit and not the central heater in the home.

On top of that, these heaters are relatively expensive since the technology is new.

So, waiting for the technology to evolve might be best before spending your hard-earned money on a panel space heater.

Propane Space Heaters

The propane space heater is the last heater I chose to feature in this list, as it’s still prevalent today.

This is the only type of space heater on this list that doesn’t use electricity.

Instead, these heaters use propane as their fuel to warm up the heating unit.

These heaters are similar to infrared heaters as they emit electromagnetic waves that heat up objects within your room.

Since they don’t use electricity, these heaters are portable, so you can bring them when camping or going on long trips.

There are some propane heaters with a fan and others without, so they are very similar to infrared heaters.

These are also some of the most affordable heaters on the market, making them great for people on a budget.

These heaters have a higher risk of fire since they use propane as their fuel source.

Additionally, some of these heaters can’t be used indoors and are only for outdoor use, so they aren’t the most practical options.

But this could be the best option if you need a convenient portable heater.

What Are the Benefits of Using a Ceramic Space Heater?

So, if there are so many different space heaters available, why would you pick a ceramic space heater in the first place?

The first advantage of using a space heater is that it runs on electricity.

Since it uses electricity to warm the heating unit, you produce clean heat with a lower risk of fires.

I personally love that because I live in an apartment.

If the heater catches fire, I risk not only my life but also the life of my immediate neighbors.

And with the price of gasoline on a steady rise, ceramic space heaters might be the more affordable option in the long run.

Another benefit of ceramic space heaters is durability.

Ceramic is a rigid material, so you can trust a ceramic space heater to keep you warm for a long time.

Additionally, ceramic space heaters are easy to use.

These modern devices come with precise thermostats that allow you to control the indoor temperature completely.

On top of that, you can quickly move a ceramic heater from room to room, so you won’t have to worry about feeling cold no matter where you are in the house.

Even if ceramic heaters are small, they pack a punch.

They can easily compete with the heat of infrared, fan, and propane space heaters.

And since they use electricity, you won’t have to worry about proper ventilation to operate the heater safely.

While shopping for heaters, you won’t find many models that can compete with ceramic space heaters.

Aside from being convenient, they are affordable.

That means that you no longer have to wonder how to DIY heat your home or try to reduce your energy bills when using a gas furnace.

That said, while ceramic space heaters are great options, they come with their own downsides.

And to give you the complete picture, I’ll discuss the downsides to space heaters in the next section.

What’s the Downside to Ceramic Space Heaters?

The biggest downside to ceramic space heaters is their lack of power when distributing heat.

Even if they’re stronger than most space heaters on the market, ceramic space heaters have the same cons as other space heaters.

As the name suggests, these heaters are designed to heat up a specific space or zone within your home.

In fact, most ceramic space heaters don’t even heat up a whole room and only work in the direction they are facing.

Another downside is that if you get a ceramic heater that uses radiation and doesn’t have a fan, you might have to wait a while to heat up the room.

So, this means you won’t feel warm immediately, which can be very frustrating, especially if your home is freezing cold.

Aside from that, you must keep ceramic space heaters running around the clock if you want them to work and keep your home warm.

Once you turn the heater off, it stops radiating heat immediately.

For example, oil-filled space heaters continue radiating heat for a while after the device is turned off.

As lovely as it would be, ceramic space heaters don’t work that way.

As a result, your electricity bill can slowly increase as you have to keep it on for longer.

And lastly, you have to make sure you set up your ceramic space heater correctly.

If there’s anything in the way of the space heater, it could prevent heat from flowing through the room.

So, just like any space heater, ceramic space heaters have their own benefits and drawbacks.

While the drawbacks don’t mean the heater isn’t worth your money, it’s still worth considering.

But if you have a small space and are looking for a small and efficient heater to use at home, ceramic space heaters could be the best option.

Are Ceramic Space Heaters Better? Conclusion

I won’t say ceramic space heaters are better than any other type of heater.

However, I can confidently say that ceramic space heaters offer many benefits you won’t find from other space heaters.

To start, you can find ceramic space heaters with or without fans, so you’ll easily be able to find one that fits your needs.

On top of that, these heaters are very efficient and do a great job of heating small spaces.

That said, ceramic space heaters aren’t ideal for large rooms and those needing the heater to work fast.

So, before buying yourself a ceramic space heater, look at your space and needs.

From there, it will be much easier to determine whether or not a ceramic space heater is the right option for you.

Is It Cheaper to Run a Space Heater or Gas Furnace?

Until my late teens, I lived in a tropical climate that provided warm weather year-round.

So when I moved up north for work, you can imagine how uncomfortable I was when temperatures dropped below 50, especially in the winter.

Aside from adjusting to the new city’s culture, I also had to find an appliance that I had never used before: a heater.

I had two options for heating my flat, and I had to decide between a space heater and a gas furnace. 

Since I had just moved in, I didn’t want an appliance that would rack up my bills and cost me a lot of money to run.

So, I tried to find out which heating appliance would work better for me while also costing me less in the long run.

I asked experts, hopped on message boards, and explored forums to find the answer.

And while there was definitely one appliance that used less power, I discovered that it may not be the best option for some people.

If you’re looking to figure out which appliance is cheaper to run and which one is the better pick for your home, you’ve come to the right place.

In this article, I’ll be explaining how both of these appliances work and which one would cost less to keep your indoors warm and comfortable.

I’ll also go over some of the pros and cons of each appliance so you can determine the better fit for your home.

How Does a Gas Furnace Work?

A gas furnace is a central heating system.

This means you can use one gas furnace to heat all of the rooms in your home on demand.

Gas furnaces can produce heat consistently by safely burning gas via their built-in burner.

Then, the heat from the burner travels to a heat exchanger, which gets very hot.

After that, the furnace blows air through the heat exchanger, warming the air before it gets released and mixed with the air indoors.

When the hot air is released, the room temperature goes up.

On top of that, you can put vents in every room so that the gas furnace heats up the entire home.

This is why gas furnaces can be a cost-effective and convenient option for larger homes.

Installing and maintaining a central heating system at home can be a huge hassle, especially if it breaks down.

So, if you’re looking for a more scaled-down approach to heating your space at home, you might want to take a look at getting yourself a space heater.

How Do Space Heaters Work?

Space heaters accomplish the same goals as a central heating system but on a smaller scale.

As the name suggests, these heaters are designed for smaller spaces, such as a single room in an apartment.

Now, suppose you have a large home with many rooms.

In that case, I don’t recommend getting space heaters, as you’ll need multiple appliances to keep everyone warm.

But suppose you live in a small apartment alone like me.

In that case, a space heater is an excellent option if you don’t want to go through the hassle of installing a central heating system.

Space heaters work similarly to gas furnaces by blowing hot air through a vent to raise the temperature.

One difference is that these heaters don’t burn gas to generate heat.

Instead, they use electricity to heat the exchanger before blowing air over it.

I own a space heater with an air purifier for my apartment, and it’s excellent for several reasons.

For one, I can point it towards me if I’m super cold and want to warm up fast.

Space heaters are also much simpler to operate, are generally safer to use, and are portable, meaning you can move them from room to room.

What Appliance Costs More to Run?

It can be hard to determine which type of heating appliance will cost more to run.

This is because you must consider the type of heater you have, the size of your home, how you plan on powering the heater, and several different factors.

With space heaters, one of your primary considerations is the size of your heater.

Generally, a smaller space heater will consume less electricity than a larger space heater.

So, if you have a larger space heater, you must prepare to pay a higher fee to keep it running.

Additionally, if you put your space heater in the hottest settings, you will consume more electricity.

But on average, experts say that an average-sized space heater costs around $60 per month to run.

However, remember that this also depends on how much your electricity costs per kWh in your area.

On top of that, the cost of running a gas furnace will also vary depending on several factors.

To start, you have to consider the cost of gas in your area.

Another thing you need to consider is how often you run the furnace and what temperature you set it to.

Again, the higher the temperature and the more often it is on, the more you will have to pay.

Generally, a gas furnace costs between $150-$200 a month.

And while that may be significantly more than a space heater, keep in mind that a gas furnace can heat your whole home rather than a single room.

With a space heater, you will be paying around $60 monthly to heat one zone or room in the home.

If you’re looking to heat the whole house, you need multiple space heaters, so the costs can add up fairly quickly.

With gas furnaces, you heat multiple rooms in the home, so it might be the more economical choice.

That said, some people would benefit more from a space heater, while others might benefit more from a gas furnace.

So, when choosing which appliance to heat your home with, consider your needs and go from there.

Gas Furnace vs. Space Heater – Which Should You Use?

So, which heater would be the best option for your home?

Well, that depends on several factors.

Here’s a breakdown of the costs and benefits of each heater to help you figure out which type of heater would work best for you.

That way, it will be much easier for you to decide which one is the best fit for your home.

Upfront Costs

When it comes to upfront costs, you will be spending much less for a space heater, especially if you’re only buying one.

Some space heaters are as cheap as $20, so they’re easily affordable if you’re not someone looking to heat up your home with DIY methods.

However, you will have to splurge more if you’re looking for a high-quality model.

Generally, space heaters in the $100-$200 range would be decent and serve you well, but you can spend as much as $300 for a top-quality option.

It’s worth mentioning that, in some cases, you might even be better off purchasing an all-in-one heater with a humidifier and an air purifier.

So if you have a bit extra money, don’t hesitate to invest in an excellent and multi-functional appliance.

Conversely, a gas furnace will cost around $1,000-$4,000.

This includes the actual furnace and hiring a professional team to install it for you.

I highly suggest hiring a professional team to install your gas furnace to ensure it’s installed properly and heats your home safely.

You might think that gas furnaces are way more expensive than space heaters and aren’t worth it.

However, keep in mind that if you buy a $250 space heater, you’ll only be able to heat one room at a time.

And when you invest in a gas furnace, you buy an appliance that will be able to heat every room in your home.

So, getting a gas furnace might be cheaper in the long run.

However, that’s if you own your property.

You won’t need a gas furnace if you rent an apartment or a small home.

I personally rent my apartment, and if I one day decide to leave, I won’t have to leave behind a gas furnace worth thousands.

Instead, I’ll grab my $80 portable space heater and take it to my new place.

Operating Costs

When it comes to operating costs, to get the most out of your money, you need to take a look at the space you’re looking to heat.

If you have a small room to heat, a space heater will be much better than a gas furnace.

This is even though electricity costs more than gas.

I pay around $100 in electricity during the winter and have my space heater on most of the time.

If you’re looking to heat a larger home with multiple rooms, using a space heater isn’t ideal, as the electricity bill will quickly rack up.

In that case, I’d recommend going for a gas furnace, which will cost you around $200-$300 per month.

This includes heating your entire average-sized home for hours every single day.

You could expect to pay double that if you heat up your average-sized home with multiple space heaters.

So, both appliances are great.

It just really depends on your current circumstances.


Regarding convenience, space heaters are the most convenient option to heat your home from two.

They don’t break often, and even if they do, you can easily replace them without calling a team to remove and re-install a new one.

Unplug the old model, recycle it, and replace it with a new one.

Space heaters will save you thousands of dollars in long-term maintenance fees, replacement parts, insurance, and other costs.

Aside from that, even if you have a larger home, you can take the space heater to another room if needed.

Most space heaters are very lightweight and easy to move around.

As someone who rents an apartment, moving in was easy, and moving out will be too.

I won’t have to leave behind a gas furnace worth thousands of dollars.

That said, keep in mind that you won’t be able to heat up a bigger space when you use a space heater.

So, when trying to find the more convenient option, consider your space and your needs, as the better heating appliance may vary for everyone.

Tips for Reducing Your Energy Bills When Using Either Appliance

No matter which appliance you end up going for, there are always things you can do to reduce your energy bills at the end of the month.

Below, I’ll share some of the little things I do to keep my home warm without it costing me a fortune.

Keep It On All the Time

This might sound counter-intuitive, but you should keep your gas furnace or space heater on all the time if you want to save money.

This will prevent the appliance from heating up a cold home or room entirely every time.

Instead, when the heater is on, it will only work when the temperature drops to maintain the set temperature.

Do note that this strategy will only work if you have an energy-efficient heater and don’t have a massive space to heat up.

Keep Your Windows and Doors Closed As Much As Possible

If it’s cold outside, keeping your windows or doors in your home open will let in cold air, which will cool down your room.

This means that the heater will need to work extra hard to heat up the new cold air you let in, which will cost you money.

You can still open your windows daily. I do that, and it’s normal.

Keep it to a minimum, though, around 5-10 minutes twice daily.

Is It Cheaper To Run A Space Heater or Gas Furnace: Conclusion

Choosing between a space heater and a gas furnace can be challenging.

To make things easy, you should consider your needs first.

Between the two, a space heater will cost less to buy and is cheaper to run if you only want to heat a small room.

If you’re looking to heat a larger room or an entire home, a gas furnace will be cheaper to run in the long turn.

This is because gas is cheaper than electricity in most parts of the world.

If you’re renting, go for a space heater every time.

There’s no point investing thousands in a gas furnace if you don’t plan on living at the property for years in the future.

Benefits of Using an Air Purifier for Your Skin

With the rising levels of air pollution, we’re already starting to see the impact of poor air quality on our skin.

The negative impact of polluted air on our skin is significant, from increased acne, rashes, and irritation to faster aging skin.

And although we can’t do much about the air quality outdoors, there’s a lot we can do about it inside our homes, thanks to air purifiers.

These appliances are becoming increasingly popular and for a good reason.

Using an air purifier has many benefits, many of which are for your skin.

But before I discuss the benefits of using an air purifier for your skin, it’s essential to understand how air purifiers work.

How Do Air Purifiers Work?

Though they might seem complex, air purifiers are straightforward machines.

Mostly, they feature a motor, a filtration system, and a fan, all enclosed in a nicely designed case.

When the air purifier is turned on, it will suck in air, push it through the filtration system, and release the air back into the room.

During that process, the polluted air remains within the air purifier.

In contrast, the clean air is released back into the room.

Each air purifier works slightly differently, but for simplicity’s sake, the above will explain how air purifiers work in most simple terms.

5 Benefits of Using an Air Purifier for Your Skin

When using the correct type of air purifier, there are five benefits that your skin will experience the most.

I will go over each one in more detail below.

Reduced Skin Irritation

Everyone gets skin irritation sometimes, but people who suffer from skin irritation daily have the most trouble.

While having a dirty pillowcase or sleeping with make-up can cause skin irritation, so can the irritants and pollution in your indoor space.

That’s where an air purifier comes in handy.

Using an air purifier will effectively remove all irritants from the air that can cause skin irritation.

Slow Down Aging Skin

As you age, your skin will too.

It’s a part of life, and there isn’t much you can do about it.

However, the impact of age on your skin doesn’t have to be as significant as you think.

Thanks to using an air purifier, you’ll give your skin the perfect indoor environment to thrive.

This will ultimately slow down aging skin and make you look younger than you are.

Reduced Dryness

If you’ve used an air conditioner at home, you’ll know how dry it can make the air feel.

When using an air purifier, you don’t have to worry about dry skin anymore.

This is because air purifiers not only purify the air but they also do it while maintaining all of the moisture in the air.

Improved Acne

When it comes to acne, air purifiers can be particularly beneficial.

Regardless of the severity of your acne, keeping your face as clean as possible from any irritants is essential.

And while you might not be touching your face with your hands, it will always be in contact with the air inside your home.

If the air isn’t purified, all the dust and solid particles floating around will come in contact with your acne and worsen things.

Reduced Rashes and Skin Disease

Germs, and pollen, amongst other irritants present in the air, are the biggest trigger for skin rashes and diseases like Eczema, Angioedema, and Hives.

Using an air purifier to cleanse the air from all of these irritants is the best way to stop skin diseases and rashes in their track before they become problematic.

What Type of Air Purifier Can Benefit the Skin?

First, you must make sure you buy a quality air purifier.

While you can find some good budget-friendly options, most cheap air purifiers feature replica filtration systems, which are not that good.

To see the most significant benefits for your skin, you want an air purifier with a pre-filter, a carbon-activated filter, and a true HEPA filter.

These filtration systems are great at capturing both gaseous and solid particles that can irritate and negatively impact your skin.

When shopping around, ensure that the HEPA filter you buy is a “true HEPA filter” and is at least class H13.

This means it has passed the HEPA standards, which means it can purify the air from 99.97% of all solid particles.

As for the carbon-activated and pre-filter, those are pretty standard and cannot be faked, though practice your due diligence before buying.

Things to Consider Before Buying an Air Purifier for Your Skin

Before you spend your hard-earned money on the first air purifier you come across, there are a few things I want you to consider.

The Filtration System

The filtration system you opt for will make the most significant difference in whether or not you get the benefits you’ve read about today.

Since air quality impacts your skin, you want an air purifier with a filtration system that can effectively eliminate all irritants in the air.

So, you want to look for an air purifier with a multi-stage filtration system.

I recommend getting a unit with a pre-filter, a true HEPA filter, and a carbon-activated filter.

Such a unit will effectively remove pollen, dust, and other solid particles affecting your skin.

It will also eliminate gaseous particles such as VOCs and smoke from cigarettes and fire, amongst others.

The Air Purification Capacity of the Unit

Not all air purifiers are designed to perform the same.

Some air purifiers have a larger air purification capacity, making them more suitable for larger spaces.

Others have a smaller air purification capacity and are designed for smaller rooms.

So, before you go out shopping, measure the square footage of your room and look for a suitable air purifier.

That way, you will buy just the perfect-sized model for your indoors.

Other Health-Related Benefits of Using an Air Purifier

Aside from the direct benefits, your skin will experience when using an air purifier, the benefits don’t end there.

Using an air purifier 24/7 inside your home will bring many other health benefits, which I’ll discuss below.

Please note that the below benefits are the ones I have personally experienced over the last five years.

Improved Sleep

One of the most significant advantages of using an air purifier while sleeping is improved quality sleep at night.

I used to wake up tired, unmotivated, and fatigued quite often.

Since I bought an air purifier and have used it when sleeping, bad-quality sleep has been rare.

So, get an air purifier if you’re having trouble sleeping at night.

Breathing in fine-quality air before and during the night will help you feel refreshed and ready to take on the day.

Lower Risk of Catching Viruses

Buy an air purifier with a multi-stage filtration system. It will effectively take care of most solid and non-solid particles.

As a result, you will get to breathe purified air free from potentially harmful particles.

This will significantly reduce your risk of breathing in viruses and bacteria that can irritate your respiratory system.

I have not had a cold in several years, despite being amongst the people most prone to catching viruses everywhere I go.

Alleviates Symptoms of Asthma

I’ve had asthma since I was young.

And over the years, the symptoms have gotten progressively worse.

This was partly to my moving to the bigger city, experiencing more stress from everyday life, and several different factors.

However, since buying an air purifier, my asthma symptoms have dramatically reduced.

Those seasonal allergies that used to bother me are now long-gone too.

Lower Blood Pressure

When I lived in India, I had to buy an air purifier to purify the air in Delhi because the air quality was terrible.

My blood pressure was through the roof, and it made sense.

My body was trying to operate while breathing heavily polluted air, which it wasn’t used to.

Studies show that reducing your PM2.5 particle intake from 11 to 7 micrograms is enough to lower your blood pressure.

Lower Risk of Diabetes

I’m not diabetic, but I came across a study that shows a strong link between the level of PM2.5 particles and an increased level of diabetes.

So, if you live in an environment polluted with PM2.5 particles, having an air purifier will reduce your chances of diabetes.


If you suffer from skin conditions, be it acne or rashes, or generally have dry skin, an air purifier can help.

Thanks to its advanced air purification system, the unit can eliminate all air particles irritating your skin and causing it to react.

And the beauty of air purifiers is that they don’t just help your skin.

They can also significantly improve your sleep quality, reduce your chances of catching a virus, and improve your respiratory health.

To reap all these benefits, you must buy the right air purifier with the appropriate filtration systems.
