Do Air Purifiers Help Remove Mold?

Yes, air purifiers can help remove mold from your home. But how they do this and how effective they truly are isn’t as straightforward as one may think.

How Air Purifiers Help with Mold

Air purifiers help with mold by trapping the free-floating spores in the filter. These spores are what cause allergic reactions in sensitive individuals.

The average mold spore is between 2.5 and 10 microns in size—an easy size for most air filters to capture. By running an air purifier, you can greatly reduce symptoms of mold allergies and stop mold from spreading through your house.

Some types of mold also release toxins into the air. These particles, known as mycotoxins, are smaller than spores at about 0.1 microns. Capturing these particles requires a more sophisticated filter, which all the purifiers on this list have.

Where Air Purifiers Fall Short

While air purifiers are great at capturing airborne spores and mycotoxins, they don’t do anything to address mold growth on surfaces. As mold grows, it will continuously release spores, and potentially mycotoxins, into the air.

You’ll need to address the mold to find lasting relief from mold.

Mold grows when porous surfaces like drywall and flooring get wet and stay moist. Typically, this happens when something is leaking or after a flood.

After the cause of the leak has been addressed, any porous surface actively growing mold will need to be removed and replaced. Harder surfaces can be cleaned and disinfected.

Once the active mold is removed, you’ll need to dry the space to prevent future mold infestation. You can use a dehumidifier to remove humidity from the air and further dry surfaces.

Info: Using an air purifier during this process will help prevent the mold from spreading and reduce respiratory symptoms.

What We Look For in an Air Purifier

There are a lot of factors to consider when looking for a good air purifier for mold. What plays the biggest role in how well a purifier works for mold is the type of filter it uses. But you should also consider the unit’s size, storability, and maintenance costs.

Filter Type

air purifier filter diagram

There are three types of filters that you can use to combat mold. Each plays a slightly different role in neutralizing mold spores and toxins.

  • HEPA Filters HEPA filters are prized for capturing tiny and large particles. They can capture 1 to 10-micron spores and 0.1-micron mycotoxins.
  • Activated Carbon Filters – Carbon filters don’t filter particles; they neutralize odors and VOCs. During the process of metabolism, molds put off a variety of VOCs, including some toxic VOCs. Having a carbon filter integrated with the HEPA filter is important to remove these compounds from the air.
  • UV-C Light – Having a UV-C light integrated in your purifier can help kill mold spores as they pass through the unit. It can also prevent spores captured in the HEPA filter from establishing and growing inside the unit.

All of the units on our list feature at least a HEPA filter capable of capturing both mold spores and mycotoxins. Many also feature carbon filters and UV light to increase overall effectiveness.

Portability and Storability

If you’re buying a purifier just to purify your air following a leak or flood, it’s important to consider how easy the appliance will be to move and store.

Smaller units are more portable and easy to find storage space for. But these units are also less effective, especially in large spaces. In our list, we awarded more points to units that showed a higher cleaning efficiency while maintaining a more compact design.

Room Size Rating

You will need to match the air purifier to the size of the room you will use it in.

Units with a room size rating greater than 800 square feet are optimal for basements, crawlspaces, and other open-air rooms with a lot of space to cover. But if you’re looking to eradicate mold in a bedroom or bathroom, a small unit can easily get the job done while saving you money in operating costs.

We chose various purifier sizes to ensure you can find the right one to fit your needs.

Maintenance Costs

Complex, multi-layer filters are great at removing mold from the air but they can be prohibitively expensive to replace when the time comes. On the other hand, cheaper filters are less effective and need to be replaced often.

Finding a quality air purifier you can afford to maintain means striking a balance between effectiveness, replacement costs, and replacement frequency.

Air Purifiers For Mold

Enviroklenz Mobile UV Air Purifier

Enviroklenz Mobile UV Air Purifier

Best Features

  • 1,000 sq ft room size rating
  • Thick, multipurpose filter system
  • Optimized for toxin removal
  • Five speed settings

The Enviroklenz UV air purifier was developed using military technology to neutralize toxic chemicals in wartime biological weapons. And it does a pretty dang good job tackling mold in the air.

The process starts with a high-powered fan that draws air through a large intake vent and over one of the thickest filters you’ll see in a home-use unit.

This filter consists of a unique earth mineral cartridge that works much like a carbon filter to neutralize odors and VOCs. This filter is especially effective against the toxic VOCs put off by some types of mold. The cartridge is also paired with a 4-inch thick HEPA filter that captures any mold spores that slip through the first filter and over 99.9% of mycotoxins.

It also comes with two UV lights to ensure none of the mold spores caught by the filters have a chance to grow or reenter the environment.

These lights can be powered on or off during use as desired.

The hefty filter on this unit is not cheap, and maintaining the UV lights adds a bit of extra cost.

You can expect to spend about $600 every two years.

Note: If you’re after a seriously powerful purifier that can effectively remove mold from the air during extensive mitigation, this is the unit you want.

The Enviroklenz is rated for rooms up to 1,000 square feet, making it perfect for basements, crawlspaces, and full house mitigation. And it has five-speed settings for highly customized use.

Alen BreatheSmart 75i

Best Features

  • Low power usage
  • Air quality indicator light
  • Customizable filters and panels

If you’re after a large capacity purifier to tackle irritating mold spores and reduce allergy symptoms throughout your home, the Alen BreatheSmart 75i is a great choice.

The standard version of this purifier doesn’t come with a ton of features in the filter department. But even without the upgrades, this purifier can help combat mold. The H13 True HEPA filter removes 99.99% of allergens including mold spores.

If mold odors, VOCs, and mycotoxins are just as much of a concern, you can easily upgrade to Alen’s Fresh filter. It uses the same HEPA filter but has an added carbon layer to remove chemical toxins and odors.

With either filter, this powerful unit can take on spaces as large as 1,300 square feet. And it does all this while using less energy than your average purifier, making it a great choice for extended use. 

Maintenance costs are on par with most average purifiers at about $100 to $140 every six months.

The BreatheSmart includes an easy reference air quality indicator light, so you know when mold levels require a higher operating speed to eradicate. 

In addition to customizable filter choices, the i75 also comes with various front panel designs so you can choose the best look to fit your home decor.

  • Multilayer filter for advanced purification
  • Slim design for easy placement
  • Low maintenance costs
  • Smart mode and air quality indicator

The HathaSpace Smart Air Purifier combines a number of unique filter types to stop mold in all forms.

These unique filters fit inside the slim body of this impressively high-rated purifier. Despite its small size, this unit can effectively purify rooms up to 700 square feet. Plus, its slim design makes it easy to place the unit in any room, on the floor, the counter, and even against the wall.

One of our favorite features of the HathaSpace is the smart auto mode function. In this mode, the unit will automatically dial the fan up or down depending on the room’s air quality. Not only does this make things easier for you, but it also saves energy in the long run.

TRACS® Portable EZ-Air Purification System

Best Features

  • Long lasting filter
  • Four speed fan
  • Medical grade air filtration
  • Large coverage area of 1,800 square feet

Similar to our top pick, the TRACS EZ-Air purification system is a utilitarian device that earns its worth by how effective it is.This metal unit is smaller than the Enviroklenz but shares many of the same great features.

The biggest difference is that this TRACS® air purifier is for spaces up to 1,875 square feet. So, whether you’re looking for a purifier to take care of mold in the basement or just to cleanse the whole house, it’s powerful enough to step up to the challenge.

Moreover, its filter system is designed to tackle both particles and VOCs. The Patented CarbonWeb® Merv 8 Pre-filter will stop mold odors and toxins in their tracks. And the medical grade H13 HEPA filter is powerful enough to remove 99.99% of particles both bigger and smaller than 0.3 microns.

The most impressive part about this unit is the lifespan of that HEPA filter. While the carbon filter needs replacing every six months, this larger filter can run up to 3 to 4 years between replacements.

That works out to just over $100 in maintenance costs each year. Not bad at all for a unit as effective as this one.

The TRACS EZ-Air has four fan speed settings, including an ultra-quiet mode for nighttime use. And it comes with a 5-year mechanical warranty for peace of mind.

AirOasis iAdaptAir Air Purifier

AirOasis iAdaptAir Air Purifier

Best Features

  • WiFi-capable app control
  • Three size options
  • Ozone-free ionization
  • Large air intakes

The AirOasis iAdapt Air provides powerful air purification and a ton of great features that make it easier to use than most.

The filter consists of multiple layers that easily target mold in every form. The activated carbon layer neutralizes mold odors and captures harmful VOCs. Next, the HEPA filter works to pull large and small particles from the air, including spores and mycotoxins.

A non-ozone ionizer and UV lamps then neutralize mold and other pathogens, completing the purification process.

Like all purifiers included on this list, the iAdapt Ait does a great job battling mold. But what sets it apart is the unique Wifi connectivity of the unit. This allows you to control your purifier from your phone no matter where you are.

The AirOasis iAdapt Air also comes in three sizes.

The small unit is portable, easy to store, and works for rooms up to 250 square feet. On the other hand, the medium unit can cover a larger area (up to 550 square feet) but is still easy to move around.

As expected, the large unit is a bit more difficult to move and store but offers the largest room coverage at 850 sq ft.

Upkeep of these units ranges from $50 to $125 every six months. Each comes with a lifetime warranty and useful extras like an air quality indicator and various run options.

Germ Guardian AC9200WCA

germ guardian ac9200wca

Best Features

  • Mold tested
  • Timer and three fan modes

This unit also has plenty of user-friendly features, such as a carrying handle for easy portability, three fan speeds, and a timer function.

The Germ Guardian is rated for rooms up to 335 square feet, but it is a surprisingly large unit. Good thing its sleek design and narrow build make it easy enough to place in the bedroom, office, or kitchen.
