Premium air purification with UltraHEPA®
Captures particles 100x smaller than the HEPA standard.
We take over 20,000 breaths per day, inhaling whatever pollutants are in our environment. Even when you’re “safe” at home your health is at risk.
Not only does outdoor pollution make its way inside, there are many indoor sources of air pollution too, including stoves, cleaning products, and building materials. In fact, the Environmental Protection Agency (EPA) says indoor air can be 5x–100x more polluted than outdoor air!
Now the good news. AirDoctor’s UltraHEPA filter removes virtually 100% of airborne contaminants as small as 0.003 microns—that’s 100x smaller than the HEPA standard.
Capture the airborne contaminants hiding in your home’s air and take control of your air quality with AirDoctor.
Inside our Premium Carbon/VOC Filter
Remove the toxic gases most air purifiers miss.
HEPA-only air purifiers only do half the job. They remove harmful particles, but do nothing to protect you from toxic gases and volatile organic compounds (VOCs):
Our premium carbon filter enhanced with potassium permanganate (KMnO₄) is the answer. The activated carbon traps gases and VOCs, and the KMnO₄ converts them into stable, non-hazardous by-products.
Get full-spectrum protection with AirDoctor.

"I have bought 3 air doctors in the last 2 yrs. Very good products."
"Filters are OK - they do what they are supposed to do. However shipping is way to high."
"Was good thanks"
"Very efficient."
"I feel very happy to have clean air for my family!"
"I cannot say enough good things about the AirDoctor 5000 Series Filters 1-Year Combo Pack. I have severe sensitivity to chemicals along with strong seasonal allergies, so clean air isn’t a luxury for me—it’s a necessity. This system has truly been life-changing. During the past two devastating wildfire seasons here in California, the AirDoctor proved its worth beyond anything I expected. Even though my apartment is well-sealed and looks spotless, the unit detected and captured an incredible amount of ash and pollutants. Seeing what it filtered out was both shocking and reassuring—it’s clearly doing its job at a very high level. Since using it, my allergy symptoms have decreased significantly. The air in my home feels noticeably fresher, cleaner, and lighter. Everything just feels healthier—like a true sanctuary from the outside environment. I’ve recommended AirDoctor to friends and family, and every single one of them has had a positive experience. One particularly powerful example: my older brother was living in an apartment with a gas leak issue. While the situation was eventually resolved, having the AirDoctor running likely played a critical role in maintaining safer air quality during that time. He’s now safe and well, and we’re incredibly grateful. If you are sensitive to air quality, dealing with allergies, or simply want the cleanest indoor environment possible, this filter system is absolutely worth it. I genuinely love these products and will continue using them for years to come."
"I ordered several filters at one time. We got half our order and had to reach out to get the rest. Except we were still short on the rest of the order when a second shipment arrived. Had to reach out again to still get the rest, nearly a month after our original order. I do like the product but definitely something needs to be worked out in shipping."
"these are a must and im disappointed they are no longer included when you buy a double set of regular filters like they used to be! Im also disappointed that i ordered these prefilterd along with a 2yr supply of the big filters and over 2 weeks later, I have NOT reveived the big filters. Air Doctor is great but prices are skyrocketing and customer care seems non existent."
"Everything in one purchase to keep AirDoctor doing it's job!"
Frequently Asked Questions
Air changes per hour (ACH) refers to how many times the air is changed with new, clean air in a given space within the span of an hour. A Harvard University Study cited by the CDC recommends at least 4 air changes per hour to effectively remove allergens like smoke, bacteria, viruses, dust, and pollen.
CADR, or Clean Air Delivery Rate, refers to your air purifier’s efficiency in removing these three contaminants over time: pollen, dust, and smoke. Higher CADR numbers indicate better air cleaning performance. The smoke CADR number is most stringent, reflecting the unit’s ability to eliminate the smallest and most dangerous particles from your indoor air.
Great question! Choosing the right air purifier will depend on the size of your room and the air circulations per hour. According to the Harvard University study, 4 air changes per hour are recommended for optimal purification. AirDoctor units are designed to meet this standard.
