The Best Air Purifiers for Mold List

1. IQ Air HealthPro Plus Air Purifier

IQAir HealthPro Plus air purifier

When I first saw this air purifier, I immediately noted it’s extensive filtration system. This is a genuine commercial grade air purifier for mold.

The hyperHEPA filter is exactly what you need to kill mold spores. It filters out all the particles that are larger than 0.003 microns so the mycotoxins released from the mold have no chance.

At the same time, this air purifier has a powerful V-5 cell gas and odor filter that deals with the harmful gases and chemicals while eliminating the odors. This is a perfect choice for musty smells that come from the formation.

This is a heavy-duty air purifier that can service rooms up to 800 square feet. Such coverage area allows you to battle the mold in your basement or on the whole floor of your house.

The unit is rather large, but it comes with caster wheels so it’s easy to move around. Another nice addition to this powerful air purifier is a remote control. You don’t have to worry about running up to the unit to change the settings when needed.

The purifier comes with a 10-year warranty, which is a clear indication of its quality. While the price tag is a little hefty, this air purifier is definitely worth the money you are paying for it.


  • HyperHEPA filter
  • Coverage area up to 800 sq. ft.
  • Powerful odor filter
  • 10-year warranty


  • Hefty price tag
  • Big size

2. Alen Breathe Smart Air Purifier

The winner of our 2020 award for best all round air purifier, comes in a close 2nd in our best for mold class. This is another monster commercial mold killer, but the IQ Air just pips it to the post in no1 position as it uses Medical Grade Hepa Filters. So if you are life threateningly allergic to mold, you really have to go for The Healthpro plus.

That’s not to say the breathesmart is a long way behind it. This truly is a powerful air cleaner. As you will see from other pages on this site, we really love this unit and have given it top marks for just about everything.

It’s especially good at purifying the air in big rooms and basements where mold growth is usually an issue. This monster machine can handle areas up to 1200 sq. feet.

Lots of smart features on this one. What I especially like is that it comes with sensors that can evaluate the level of work required and can automatically shut down, when it feels the air is fully filtered. A great energy saving feature.

It has really simple controls. Very intuitive. They’re also hidden out of sight, so you don’t spoil the ultra sleek modern design.

It comes in a huge array of different front panel color options to choose from. So matching it to your decor is really easy for all of us.

One slight downside is that there’s a fairly short shelf life on the filters. The manufacturer recommends filter replacement once every 9 months, but personally I think you can stretch that out to 12 months if your air quality isn’t too bad. The filters aren’t the cheapest to replace, but fairly reasonable for a unit of this size.

This air purifier consistently gets top marks for mold and mildew purification and excels in scientific studies. The Mold and Bacteria filter is superb at picking up and destroying airborne mold and viruses. Everyone here at Freshairguide agree this is the best air purifier around right now


  • Choice of filters
  • Sleek design
  • Quiet fan
  • Smart auto shut down when air quality is good
  • Covers up to 1200 sq. ft.


  • Fairly frequent filter changes required

3. Fellows AeraMax 300 Air Purifier

The reason I chose the Aeramax 300 as one of the top mold killing purifiers is due to the AeraSafe antimicrobial filter. It’s designed to protect the True HEPA filter from mold, mildew, bacteria and other viruses. This will drastically prolong the life of the hepa filter, which is the most expensive filter to replace on all air purifiers.

The unit also comes equipped with an ionizer they call PlasmaTRUE technology. Ionizers have proven to be especially adept at zapping even the tiniest of microbial bacteria.

I really like the design of this unit. Very modern looking and it feels exceptionally well built.

Like the Alen machine above, this unit comes with an auto shutoff feature that can detect when the air is pure enough to shut down temporarily. It’s a real money saver both in terms of electricity use, but also to preserve the filters for as long as possible.

Another great feature is the Aera+ Mode, which increases the air turnover rate by 50%. This can be really useful in cold and flu season when we’re more at risk from airborne viruses.

One slight downside is that it’s not really great for bedroom use due to a fairly loud fan on higher speeds and display lights that you can’t turn off.


  • 4 Stage filtration process
  • Sleek design
  • Great price for the Coverage
  • Sleek design
  • Very easy operation


  • Fairly loud on higher fan settings
  • Bright display lights that can’t be turned off

4. Winix 5300-2 Air Purifier

I like this air purifier for its 4-stage filtration system that aims to fully remove mold from all indoor air.

It includes a pre-filter, an activated carbon filter, a HEPA filter, and an ionizer. While it can only cover the area of under 360 square feet, it’s a great fighter for average sized rooms.

TrueHEPA filter can easily deal with the spores since it captures 99.97% of particles 0.3 microns in diameter. Meanwhile, the activated carbon filter can fight the odors produced by the mold growth.

The PlasmaWave technology captures and eliminates the mold spores by producing negative ions and creating special plasma clusters.

One of the main advantages of this air purifier that attracted me is the quiet operation. Even when at the highest setting, the fan doesn’t produce a noise louder than a quiet conversation. This is a wonderful air purifier for bedrooms and living rooms. It’s equipped with various sensors that help you adjust the settings for your needs.

It also comes with a filter indicator that tells you when the trueHEPA filter needs to be replaced. This is an important feature for homeowners since changing the filters on time is compulsory.


  • 4-stage filtration system including ionizer
  • Quiet fan
  • Filter replacement indicator
  • Covers up to 360 sq. ft.


  • Isn’t suitable for large areas
  • Activated carbon filter needs to be replaced every 3 months

5. Coway AP-1512HH Air Purifier

Coway AP-1512HH Air Purifier

I chose this as one of the best hepa air purifier for mold due to its great filtration system, a variety of sensors, and a compact design. It can service the area up to 360 square feet, which makes it a good choice for most of the average-sized rooms in the house. It can fight using the trueHEPA filter and fight the odors with the activated carbon filter. The unit also comes with an optional ionizer, which offers an additional hand in the process.

I also liked the compact design of this air purifier. Various objects in your home can hide it since it’s not too high. You can easily carry it around the house whenever you need some assistance in other rooms.

One of my favorite features of this ionizer is the eco mode. Once the air quality sensor determines that the air has been staying fresh for over 30 minutes, it automatically turns the air purifier off. This is a great energy saving option. The air purifier is also equipped with a timer, which allows you to set the time when you want the air purifier to stop working. This is a useful feature for busy homeowners.


  • 4-stage filtration system, including ionizer
  • Eco-mode
  • Air quality sensor
  • Sleek design


  • Loud operation when on 3rd fan speed setting
  • Absence of sleep mode

6. Levoit LV-Pur131 Air Purifier

We gave this air purifier a really high rating in our main review of it earlier in the year. The reason for this is simply that it offers fantastic value for money.

Levoit have long been known for producing high quality air purifiers, all of which get amazing reviews from the amazon buyers and professionals alike.

The Pur131 comes with some of the best filters in the industry and a ton of smart features like a timer, quiet operation mode, an air quality sensor and filter replacement indicator to name just a few. You don’t typically see this level of features from such a well priced machine.

The reason I believe this unit will be tough on Mold is that the true HEPA filter that levoit use in all their air purifiers is among the best Hepa filters out there currently. This is the main filter in any air purifier and the one tasked with removing mold spores and mildew from the air. So it goes without saying that this air cleaner should be up to the task.


  • Beautiful design
  • Lots of smart options
  • Extremely energy efficient
  • Seriously good value for money


  • Cleans a smaller area than manufacturer states
  • Replacement filters not quite as cheap as competitors

7. Pure Enrichment Purezone 3-In-1 Air Purifier

Whilst Pure Enrichment are fairly new to the air purifier game, they are certainly not messing around. This little purifier is absolutely awesome and I love it.

For a price well under $100, this little unit packs a powerful 4 stage filtration system to kill any trace of mold spores from the air. A true Hepa filter is backed up a UVC light to kill off any other bacteria and fungi it might have missed.

Along with this excellent filtration system, you get a variety of smart options in a super sleek design that can happily work away in your bedroom without disturbing your sleep. It’s super quiet and you can turn off the display lights.

This little unit offers serious bang for your buck and, whilst it can only clean small rooms, it does so very well.


  • Very quiet, good for a bedroom
  • 4 Stage filtration
  • Low maintenance fees
  • Easy filter replacement


  • Only suitable for smaller sized room and personal space

8. Levoit LV-H132 Air Purifier

Until the purezone came out, the LV-H132 easily beat off all competition in the small air purifier market with it’s excellent filtration system and fantastic design.

The already bargain price of this unit has recently been reduced further, making this one of the cheapest mold busting little air purifiers you can buy.

As long as you only need to purify small rooms or have it sitting on your desk blowing pure air directly on you, this little unit is the way to go.


  • One of the cheapest air purifiers around
  • Great Design
  • Low maintenance fees
  • Compact and lightweight


  • Only suitable for smaller sized room and personal space
  • Only one smart sensor

How to Choose a great Air Purifier for Mold?

Things to look for when purchasing an air purifier for mold

If you’re wondering how to get rid of mycotoxins, you’re in the right section.

I touched on how big mold spores are earlier. They range from about 1- 100 microns in size. This means you have to buy an air purifier that can battle such microscopic particles.

To do this you need a special kind of filter inside your purifier called a Hepa filter. The best hepa filters for mold are able to take care of 99.97% of particles 0.3 microns in size. This means Hepa filters are best at removing mold from the air. they can easily deal with the problem. In order to keep the air clean, you have to make sure to change the filters on a regular basis.

Spores that fly through the air are invisible to the eye. However, the musty smell sometimes produced by it can be obvious and unpleasant. In order to combat such odors, you need to look for an air purifier with an activated carbon filter. These filters absorb the odors and make the air fresher and easier to breathe.

Another important air purifier feature that can fight the mold spores is a negative ionizer. An ionizer releases negative ions that stick to the mold particles and allow them to be easily caught by the rest of the filters. Some people are not big fans of ionizers since they believe they produce ozone. This is not true anymore. Modern ionizers are not harmful to humans while they can effectively tackle the problem.

An ultraviolet lamp option in an air purifier is rare, but it can be a nice addition to the rest of your killing artillery. While it won’t get rid of the problem on its own, it can give a nice hand to the filers and the ionizer.

An ideal air purifier for mold should have an activated carbon filter, a HEPA filter, an ionizer and a UV lamp. Generally, a carbon filter and a HEPA filter are enough while the ionizer and a UV lamp are just nice additions that can help you in your fight.

Do You Suffer From Mold Intoxication Symptoms?

headache caused by mildew

A little occasional wheezing or coughing might seem like a nuisance to many of us. What we don’t realize is that there might be much bigger problems standing behind the symptoms than the simple flu. The slight discomfort can easily turn into a full blown illness. In some cases, mold formation leads to death.People at higher risk for mold allergies are people with chronic lung illnesses, which will result in more severe reactions when exposed to mold.

The Environmental Protection Agency (EPA) reports that all types of molds may be dangerous for your health and can be especially dangerous to people in high risk categories such has those with a weekend immune system or lung defects and illnesses.

The symptoms that people suffer from when exposed may vary. The severity of them can be differ too. They depend on many factors, such as age, overall health condition, your sensitivities or allergies.

People who suffer from mold exposure often experience the following symptoms:

  • Headaches
  • Muscle and/or joint pain
  • Depression
  • Vision problems
  • Immune system problems
  • Fatigue
  • Problems with GI
  • Wheezing
  • Coughing
  • Shortness of breath
  • Anxiety

Each one of these symptoms may be caused by other conditions. However, if you suspect you might have mold in your home, you need to act as soon as possible. The above symptoms don’t all appear at once. They might come and go. You need to carefully watch your health and try to keep the air in your home as clean as possible.

Remember, for most people it’s not what comes to mind when you first experience the above symptoms. Your physician might not be proficient in mold related issues. That’s why when you start experiencing these problems, you might be on your own.

An air purifier can help you keep the air clean and free from spores. While buying an air purifier won’t save you from doing some serious cleaning, it can help you get rid of the symptoms and start enjoying fresh air in your home.

Where to look for Mold?

Wiping the surfaces clean and watching for new growth is compulsory. However, it might not eliminate the problem completely since the mold spores won’t go anywhere. They’ll just settle on another surface and continue flying through the air. If you want to battle the problem that contaminates your home, you need to first find and destroy the source and also get a good air purifier that provides active mold control.

The main problem that we face is the way it reproduces. Fungi send the spores into the air so they find other places to settle. While the spores are airborne, they are invisible. That’s exactly when they cause most of the respiratory problems.

Sometimes there are many thousands of spores present in one small room. The spores are usually about 1 to 100 microns in size and easily inhaled. In order to get rid of such particles completely, you’d need to run the air through a high-quality filter that deals with such small contaminants. Most of the air purifiers available on the market today are equipped with HEPA filters that deal with 99.97% of particles 0.3 microns in size. This means they won’t have trouble filtering out the mold spores.

Most Molds typically like damp and humid environments, which is why we usually see many types growing in our bathrooms. Especially around the bath or shower which are exceedingly wet environments that growth can be rampant if left unchecked. Same goes for the toilet.

Spores are very hard to kill. They can survive extremely harsh conditions, including dryness and can stay alive for years waiting for the favorable environment to start growing in. It doesn’t need any specific surfaces to start growing and can live almost anywhere as long as there’s oxygen and moisture.

You can find it on wood, plastic, leather, rocks, tiles, and more. It feeds on whatever surface is beneath it. This is especially unfortunate when that surface is your floor or furniture.

Mold and Mildew start to really kick up into high gear when there is ample moisture around. While the air purifier can help you eliminate the spores in the air, it won’t get rid of the growth. In order to stop the vicious cycle of reproduction, you need to find the mold and then kill the fungi and control the moisture levels in order to prevent mold growth.

Look for new growth in the following places:

  • Bathroom (under the sink and around the bathtub)
  • Kitchen (around the sink and under it)
  • Behind appliances that produce moisture (refrigerators, dishwashers, laundry machines)
  • Attic (roof leaks)
  • Around the windows
  • Basements

Before seeing the actual growth, you may first notice a musty odor in you room when the windows are closed. You might also see water stains on your walls or ceiling, discoloration on the carpet and black or white specks on the walls. At the same time, you might start experiencing respiratory problems. This means you have to start fighting the mold and think about reducing the amount of moisture in your home. The humidity levels must be kept below 60 %.

What Type of Mold Do You Have In Your Home?

Microscopic mold spores

There are over 400,000 types of mold in the world. Thankfully, only about a 1,000 can live in the households and attack your clean indoor air. These types are divided into three groups.

Allergenic. These types are not dangerous unless you have allergies or other respiratory problems, such as asthma. Younger children are especially susceptible to airborne spores.

Pathogenic. These are more dangerous types that can evem cause infections. They don’t affect 100% healthy people, but if you have a compromised immune system, then they might cause serious lung diseases.

Toxic. The most dangerous of all the groups of Mold. This group includes the infamous black mold, which as we know, can affect everyone. The molds in this group can suppress the immune system and can cause cancer. These types all generate mycotoxins that damage your health once inhaled. You can get adverse effects by just touching them.

In our homes, we mostly face five varieties of mold. They are:

  • Alernaria – settles in your nose, mouth, and upper respiratory tract and is a major cause of allergic reactions
  • Aspergillus – Commonly found in extremely humid climates. It settles on the house dust and can produce mycotoxins, which cause various lung infections.
  • Cladosporium – This one settles on textiles, wood, and other porous surfaces. It can cause hay fever and asthma.
  • Penicillium – Likes to grow on wallpaper, carpets, and fiberglass insulation. It can cause asthma and allergies. May produce mycotoxins.
  • Stachybotrys – Toxic mold aka black mold that generates mycotoxins and causes serious problems, such as lung bleeding. It’s much less common in the households than the other four types. It can settle on wood or paper, but not on tiles or concrete.

How Can You kill Mold?

tip for getting rid of mold on ceiling

Whatever method you use to get rid, be it physical cleaning or ultraviolet light mold removal, the main problem is the spores. When you pick up an infected carpet, the spores fly up into the air and go searching for new surfaces to settle on. As they are so light, they can stay in the air for a very long time. The only way to make your fight with the mold effective is to use air purifiers to suck up the spores. It’s especially important to have an air purifier working when you are physically removing the pieces of mold. Otherwise, your work may be absolutely futile.

I’ve been battling it in my home for many years due to the high humidity. Until I purchased an air purifier, I was losing the fight. Many people don’t realize that mold is not just what they see on their walls or floors. The main enemy is in the air and it’s absolutely invisible.

You maybe wondering air purifier or dehumidifier for mold? – well, I have to say – if you live in a high humidity you probably need both. But if I had to choose only one, it would be an air purifier all day long.

While looking for an efficient way to fight it, I’ve heard about UV light. It seems like an easy way to blast spores out of existence. But does black light kill mold completely? Unfortunately not. In order for the black light to work, the UV ray has to be extremely close to the spore. This means that any spores that fly away from the UV light, evade capture. Sometimes black light might kill up to 90 % of the spores in the air. 90 % seems a lot, doesn’t it? When it comes to the spores, anything less than 100 % is too little. If you allow even a few spores to live, you’ll have new mold forming at the speed of light.

When you are physically removing it from a surface, don’t forget to spray a disinfectant before touching it. This will reduce the number of spores that fly up into the air once the mold is disturbed. But in order to make sure that all the spores are gone, you need to purchase an air purifier with an HEPA-type filter.

Please note that if you have a big problem, you might not be able to deal with it on your own. You have to hire professional help to get rid of all the mold in your home. While the professionals are doing their job, make sure you have the air purifier working and eliminating all the spores from the air.


So, I hope my guide helped answer your question of do air purifiers work for mold?…The answer is emphatically YES!.

While the IQ Air HealthPro Plus doesn’t have an ionizer but some others do, I’ve decided to name it the best mold air purifier in 2020, due to its heavy-duty filtration system. The hyperHEPA filter takes care of all the spores in the air, while the V-5 filter deals with the odors. Even though this air purifier is more expensive than the other options, it can service more than twice the area while offering a powerful protection.
