What the experts are saying
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.

"I bought this for using in a fixer-upper house that smelled strange. The filter has gotten rid of the smell in the living area. I love the auto feature on this product. When we are working in the back part of the house, the air in the front living space stays clean because the auto feature will kick up the air purification as necessary."
"The room we have it placed in had a very distinct odor that was especially noticeable when you entered the room. The smell was gone within 24 hours of first turning the AirDoctor on and has not returned since. It is very quiet. We are VERY pleased and highly recommend the AirDoctor."
"We use an AirDoctor 2000 in a smallish bedroom and it keeps the air super clean. When we ordered four units of varying sizes from AirDoctor, the delivery time was only about four business days, even though the transit was from halfway across the country. There was one mistake in the units sent (one size was doubled up and one omitted), but the person on the helpline at AirDoctor was gracious, friendly, and helpful in correcting the error. More recently, we purchased another AirDoctor 2000 for my office space, but in that instance, the shipping experience was far less satisfactory. There was a different shipping outfit involved and the item was not delivered and, ultimately, could not even be located at the destination warehouse. Hopefully, AirDoctor will reconsider its shipping choices and go back to using FedEx, which was the rapid and reliable shipper."
"The 2000 is a nice small air filter that is super light to move around. I expect the same filtering quality that already have in a larger version, 3000 that i bought 4 years ago"
"I have been using my air filter for a month. I live in Colorado. We’ve had alot of wildfire smoke. It has made a huge difference in my allergies and my ability to breathe during the hot Colorado Summers."
"Fast shipping and great product"
"I love my AirDoc! Saving up now to purchase a second for the rest of my apartment (this one is in my bedroom)."
"This is a great product. I have purchased probably ten over the years and put them in my children’s as well as my granddaughters home. Great job!!"
"Corrupt Company, do not support these people."
"It doesn't automatically restart after a power outage. I would have liked to be able to program a schedule to change the fan speed."
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.
