Air Purifier For Mold FAQ

How does an air purifier for mold work?

mold in garage

When mold spores are airborne they can be sucked into an air purifier, therefore being eliminated from the air. They are essentially trapped by the purifier’s filter, such as a HEPA filter, so that they die.

They can’t continue to survive in the purifier or reproduce as there is no moisture present in the device. True HEPA filters can eliminate up to 99.97 percent of pollutants and mold spores that are 0.3 microns in size! 

What type of mold and mildew do they filter?

Air purifiers that specifically state that they can remove mold will usually make use of HEPA filters. Now, we’ve already looked at how they can remove mold spores, but what kind of mold? 

Air purifiers can remove a variety of mold spores from the air. Allergenic mold has fungal spore sizes that range from around two to three microns, so air purifiers that can remove particles which are smaller than 0.3 microns will definitely remove these from the air. 

Other common types of mold that you’ll find in the home and which can be eliminated with an air purifier are aspergillus (which is between 2 and 10 microns in size) and causes symptoms such as asthma, and Cladosporium (which is between 2 and 3.5 microns) and can cause allergies as well as asthma.

Penicillium, which is two microns in size and can cause a variety of symptoms such as headaches, rashes, and congestion, is another mold that can be effectively removed from your home with the use of an air purifier. 

Mold spores are generally between one and five microns in size, so air purifier filters can successfully eliminate them from your home’s indoor air.

As for mildew, which is surface fungi that’s usually gray or white and found in moist areas, can also be eliminated by the use of an air purifier. This is important because once mildew takes hold on surfaces, such as due to poor ventilation, it’s more difficult to remove.

It’s important to remember that air purifiers won’t remove the mold infestation in your home. If there’s a reason for the infestation, such as moisture from leaks in the home, you’ll need to treat the source of the problem. 

Do air purifiers deodorize air?

purifier in living room

Air purifiers won’t actually deodorize the air because they work to remove pollutants and odors that are currently in it. They make use of fans to increase air circulation in a room.

Then, their filters absorb pollutants and chemicals that are present in the air and which are causing it to have unpleasant odors. Activated carbon filters are the ones that work well to remove those unpleasant odors.

You can find activated carbon filters in air purifiers such as the SilverOnyx air purifier we featured in our reviews of the best air purifier for mold and mildew. 

With the use of an air purifier, your air will certainly be cleaner, but it won’t be deodorized. You can eliminate a range of different odors from the air with the use of an air purifier. These include smoke, pet odor, garbage, smelly cooking, and more. 

How large of a room can you filter?

There are many different room sizes that air purifiers will be able to clean. It’s important to find an air purifier that is strong enough to clean a large room if that’s what you need it for.

Generally, small air purifiers will be able to clean the air in rooms that are up to 299 square feet, while medium air purifiers will be able to clean rooms that are between 300 and 699 square feet. Finally, ones that are suitable for large rooms will be able to clean between 700 and 1,900 square feet.

The Alen air purifier we featured in our reviews can easily clean air in an area that’s 700 square feet, so it’s worth considering if you’re looking for a more capable purifier.

How much electricity do they consume?

Before we look at how much electricity air purifiers use, it’s important to bear in mind that many devices on the market are certified as Energy Star models. 

Generally, though, you’ll be pleased to know that air purifiers don’t use a lot of energy. The average power that an air purifier will use is around 50 watts. This is very little. 

Of course, it depends on how much you use the air purifier. The standard air purifier that runs continuously would use 458kWh per year in electricity, which is the equivalent of a new refrigerator.

However, air purifiers that are Energy Star certified will be approximately 27 percent more energy efficient than standard air purifiers, which can result in saving you energy and money – you’re looking at saving approximately 124kWh per year and  $16 every year on your electricity bill (via Energy Star).  


If you have a mold problem in your garage, it’s essential to get it sorted out.

You need to get your hands on the best air purifier, and the bonus of doing this is that it will be able to tackle many other problems you might be dealing with when it comes to the quality of your indoor air. 

Air purifiers can tackle bad odors, bacteria, pollen and other allergens, and more! They’re a valuable investment to ensure that you maintain the health of your indoor air. 

What is the best air purifier for mold?

If you spend a lot of time working in your garage, make sure you choose the best air purifier from our list of reviews to keep your indoor air cleaner and safer, for you and the whole family.
