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.
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):
- Toxic gases: ozone, nitrogen dioxide, etc.
- VOCs: benzene, formaldehyde, & more from furniture, flooring, cleaning products, etc.
- Health risks: Asthma, cognitive decline, cardiovascular disease, & even cancer
Removes more pollutants than ordinary purifiers
AirDoctor captures 99.99% of airborne particles.

Frequently Asked Questions
Why are air changes per hour (ACH) important when shopping for an air purifier?
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.
What is CADR, and why’s it important?
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.
Which air purifier is right for me?
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.
How often do I need to change the filters?
AirDoctor 4000 & 1000: Replace UltraHEPA® and Carbon/VOC filters every 6 months.
All other AirDoctor units:
- Replace Carbon/VOC filters every 6 months.
- Replace UltraHEPA® filters every 12 months.
The indicator light on your AirDoctor will also light on when it’s time to replace your filter
– no more guesswork!
