Best Air Purifiers for Mold Reviews 2022

The best air purifier for mold comes with dedicated mold battling features that are missing from standard air purifiers.

For example, most air purifiers for mold spores come with ultra-efficient HEPA filters that typically capture up to 99.97% of airborne particles down to 0.3 microns(in diameter).

Thats significant because mold spores are generally sized1-20 microns meaning theyre easily filtered out by the specialized HEPAfilters.

Others come with integrated ionizers to help controlairborne mold and can be very beneficial if you if youre sensitive to mold.

This article will explain everything you need to know about the best air purifiers for mold and how to go about identifying the best air purifier for mold.

Sound good? Lets dive right in…

Can air purifiers remove mold?

The short answer is yes….

Air purifiers for mold spores employ proprietary filtrationtechnologies to thoroughly clean mold from the air circulating in your rooms.

Whats more, they get rid of the unpleasant smells coming from the mold by absorbing the triggers- carbon compounds such as mVOCs and VOCs, as well as mycotoxins.

Having said that, an air purifier for mold wont eliminatethe mold thats already growing on surfaces though they block the formation ofnew mold colonies.

You should thus simultaneously adopt other strategiesincluding keeping your surfaces squeaky clean and addressing the source of the moistureto fully win the battle against mold.

Types of air purifiers for mold

The major difference in these types of air purifiers is theair purifying technology used.

As a result, you may find your unit working better than afriends.

Here are the dominant types:

HEPA (High-Efficiency Particulate Air) Air Purifier

By far the most effective, these air purifiers use HEPA filters that have been certified to trap up to 99.97 percent of mold and other particles as small as 0.3 microns.

Their mechanical fans also arrest dust, pollen, pet dander, and most common pollutants.

They, however, do not eliminate gasses and smellsso most manufacturers add a carbon-activated pre-filter to eliminate the odor-causingmolecules. 

Activated Carbon Air Purifiers for mold

As hinted above, these are brilliant in adsorbing the musty smells coming from mold and mildew to freshen the room.

And like the name suggests, the secret is the includedactivated carbon which removes the microbial volatile organic compounds(MVOCs), the primary cause of the nose-wrinkling odors.

I already explained that most HEPA air purifiers for moldwill have an activated carbon pre-filter. 

UV (ultraviolet light) air purifiers

This category of air purifiers usesshort-wave ultraviolet light (UV-C) to kill microorganisms andairborne pathogens including mold, viruses, and bacteria.

They again superbly destroy airborne mold spores and itcommon to find a UV-C light installed in some of the topmost HEPA models.

Ozone Generators

Ozone generators destroy living mold spores and certainpollutants by producing ozone and can be quite efficient too.

But we dont recommend them since ozone is unsafe to inhaleand can cause chest pains, throat irritation, persistent coughing, shortness ofbreath, and lung-tissue inflammation to name but a few. 


Air ionizers cleanse contaminants by ionizing(electrically charging) air molecules and are effective on variousparticulates, odors, and infection-causing microbes.

The electric charge can, unfortunately, create some ozonetoo and potentially irritate your lungs besides worsening allergy andasthma symptoms. 

Air purifier for mold Buying Guide

Before we proceed to the reviews, lets briefly discuss whatto look out for when shopping for an air purifier for mold spores.

Room size (coverage area in square feet)

The first key consideration is the size of the room that youwant to purify.

For starters, go for AHAM (Association of Home ApplianceManufacturers) Verified clean air delivery rate (CADR) units.

Now, AHAM uses the CADR to independently measure an air cleaners efficacy in purifying pollen, tobacco smoke, and dust and the unwritten rule is for the CADR to be 2/3 of your rooms area.

That means that if your room is 120 sq. ft. (10×12 feet), you should aim for an air cleaner with a CADR of 80(2/3 of 120) and above for the stated pollutants.

Energy efficiency

Most of the leading models are energy-efficient and willsave you from the mold without giving you a heart attack from astronomicalenergy bills.

But you can still stumble on units devoid of energypreservation features and which cause a notable spike in your bill even ifyou run it for a few hours.

You definitely want to keep off such units.

An ideal starting point would be to look for brands with theenergy star logo.

Filter replacement costs

The other cost I would like to point out is replacement filters.

You see, the filters (HEPA and carbon) work perfectly on themold for a set period, after which you have to replace them for continuedefficiency.

Some are priced as high as $200 and need to be changed every3-12 months.

Be, therefore, sure to factor in the filters cost andfunctional duration before your final decision.

But you shouldnt fret- some models come with reusable (washable)filters and can be a cost-effective option.

Noise level

Some brands are extremely loud and youll struggle to keep aconversation going.

Note the decibels listed on the website/manual at both the highest and lowest fan settings and compare.

As a guide, any model below 50 dB is consideredexceptionally silent.

Other considerations

You shouldnt overlook essentials like:

  • Portability-You want a good size and above all, an easily portable unit.
  • Thelength of the warranty- Needless to say, the longer the warranty, the morepeace of mind for you. Also, find out what other buyers are saying aboutcustomer service and support.
  • The looks-We all want them elegant and unobtrusive. Dont we?
  • Extras-Additions such as Wi-Fi connectivity, a timer, a supporting app, a remotecontrol, color-changing night lights, smart sensors, and more make it all themore compelling.
