Why standard HEPA filters aren’t enough for mold toxins

HEPA filters work great for mold spores, since mold spores are typically 2-10 microns.

But capturing smaller and scarier mycotoxins released by common household molds is trickier. That’s because mycotoxins are around 0.1 microns, and the HEPA standard doesn't account for particles that small.

AirDoctor’s advanced 3-stage filtration system features a proprietary UltraHEPA filter, which removes 99.99% of harmful airborne contaminants as small as .003 microns. That’s 100x smaller than the HEPA standard—and includes harmful mycotoxins at ∼0.1 microns.

Get the high-performance air purifier that goes beyond standard mold spore capture to target mycotoxins—a critical issue that can harm both your physical and mental health.

5 common hiding spots for mold

Mold starts to grow in as little as 24-48 hours.

Bathrooms

Steam and standing water create the perfect environment for mold growth.

  • Grout, caulking, and shower curtains
  • Toilet tank condensation that drips onto the floor

Laundry rooms

High humidity and organic fibers make laundry rooms a mold hotspot.

  • Rubber door gaskets on front-loading washers
  • Clogged dryer vents that trap moist air in the wall

Basements

Underground areas are prone to seepage and persistent humidity.

  • Hairline cracks in foundations let groundwater in
  • Uninsulated pipes that sweat & drip in summer

Closets & behind furniture

Mold thrives in stagnant air trapped inside closets and against walls.

  • Heavy outdoor furniture against exterior walls
  • Dark, damp closets that spur mold growth

Attics & roofs

A perfect storm of excess moisture and insufficient ventilation.

  • Roof leaks
  • Exhaust fans that vent moisture into the attic

Mycotoxins can make you sicker than you think

And the symptoms often go misdiagnosed for months.

  • Respiratory issues: Coughing, wheezing, lung inflammation
  • Cognitive concerns: Brain fog, anxiety, depression
  • Skin reactions: Rashes, hives, itching, dryness

Frequently Asked Questions

Do air purifiers help with mold?

Yes, but with a caveat: an air purifier can capture airborne mold spores, which helps prevent them from forming mold colonies, but it can’t eliminate mold that’s already growing. Also, HEPA filters trap spores rather than kill them, so replacing filters on schedule matters.



Where AirDoctor goes further: mold also releases mycotoxins, which are far smaller than mold spores. AirDoctor's UltraHEPA is independently tested to capture particles as small as 0.003 microns — 100x smaller than standard HEPA — so it captures airborne mold spores and the finer mycotoxins too.*

*Mycotoxins are an indicator of mold growth in the home. While AirDoctor can capture mold spores, it is not a replacement for professional mold abatement.

Does the carbon filter help with mold?

Yes — it handles a different part of the problem. That musty, damp smell mold produces isn’t the spores themselves; it’s a set of gaseous compounds called MVOCs (microbial volatile organic compounds). Those pass through a HEPA filter, but they're exactly what activated carbon is built to adsorb. So the carbon filter is what actually addresses mold odor. 


Further, AirDoctor’s carbon stage pairs activated carbon with potassium permanganate to trap those gases and VOCs and convert them into stable, non-hazardous by-products. Together, the two filters cover both sides of mold: the airborne particles and MVOCs which cause the odor.

What is CADR, and why's it important?

CADR, or Clean Air Delivery Rate, measures cleaning power—the speed and volume of clean air delivered by the purifier, usually in cubic feet per minute (CFM). A higher CADR numbers means better performance.

Which AirDoctor is right for me?

It depends on your room size. Basically, the bigger the room, the bigger the AirDoctor. 

When deciding, the key numbers to consider are:

  • The room’s square footage (sq. ft.)
  • The model’s air changes per hour (ACH)

ACH measures cleaning frequency—how many times a particular model circulates (cleans) the air in a room in 1 hour.

A Harvard University study cited by the CDC recommends at least 4 air changes per hour to effectively and efficiently remove allergens (dust, pollen, pet dander, mold spores, etc.) smoke, bacteria, and viruses.*

What’s the difference between a HEPA filter and UltraHEPA® filter?

HEPA filters are tested to capture 99.97% of airborne particles as small as 0.3 microns. UltraHEPA is a medical-grade filter that exceeds that standard. AirDoctor's UltraHEPA filter is proven to capture 99.99% of airborne particles as small as .003 microns. That’s 100x smaller than the HEPA standard!

How often should I change the filters?

The change filter alert will let you know when it’s time to change a filter, so you’ll never have to guess.
Environmental factors (like how dirty your air is) can affect filter life, but the typical timeframe is:

Pre-filter: Every 6 months*

Carbon filter: Every 6 months

UltraHEPA® filter: Every 12 months

*The pre-filter is attached to the carbon filter. We recommend vacuuming the pre-filter with a brush attachment once a month to help extend the life of the carbon and UltraHEPA filters.

Where can I buy replacement filters?

When it’s time to replace a filter, make sure you get the real thing! Shop directly on our site at airdoctor.com.

Here’s why: generic knockoff filters will degrade your AirDoctor’s performance, failing to protect you against serious airborne threats including harmful microscopic particles and toxic gases. Plus, those inferior filters cost more in the long run by decreasing your AirDoctor’s lifespan and voiding your warranty.

Do you offer payment plans?

We sure do—we partner with two leading U.S. financial technology companies that provide “buy now, pay later” services. Simply tap or click “See Details” next to the Affirm or AfterPay logos during checkout to explore those options. Terms and conditions apply.*

*Various purchase plans are available based on approval. Affirm is not available in Iowa or West Virginia due to state-specific financial regulations.
