Why are air changes per hour (ACH) important in shopping for an air purifier? 

If you’re not moving the air, you’re not cleaning the air. Experts recommend at least 4 air changes per hour for optimal removal of airborne particles from the air. You can rest assured that AirDoctor purifiers are powerful enough to clean the air 4 times per hour, or every 15 minutes, for their respective room size coverage to deliver you pure, protected air. Many air purifiers base their room size coverage on only 1-2 air changes per hour (ACH). It is important to check that an air purifier has a high enough CADR to circulate the air in the room at least four times per hour.

How Often Do I Need to Change the Filters? 

AirDoctor 3500: Based on 24/7 operation, the Carbon/VOC filter should be replaced every 6 months and the UltraHEPA® filter should be replaced every 12 months. We recommend replacing filters when your Filter Change Alert indicator light signals for a filter replacement.

AirDoctor 3000/3500 and 5000/5500 replacement air filters
To keep your AirDoctor Air Purifier functioning as efficiently as possible, you'll need to replace your air filter on a regular basis. Whether you're using an AirDoctor 3000/3500 or an AirDoctor 5000/5500, if it has been operating 24 hours a day, 7 days a week, you'll only need to change your UltraHEPA™ filter once a year and the Carbon/Gas Trap/VOC filter once every 6 months. But in case you forget, the AirDoctor's Change Filter Alert will conveniently let you know when you need a replacement.

working great after 1 year

Bought this off Mike late 2022, I have been running it non stop for over a year and it has been perfect, auto mode works great and at night i run it on high with ionizer on - well built unit with no issues. The filters are a few bucks cheaper on health ranger than they are at airdoctor. the Dust build up is now cut in half in my home- my furnace filter now last two to three times as long since i have been using this unit

We are incredibly grateful that you took the time to leave us a positive feedback

Excellent Home Air Filter

I bought my first AirDoctor from the HR several years ago for my home when we had the bad California fires and it did an excellent job in filtering the air in our home. Great to use when cooking to help absorb the smells too. I love it so much I am buying one for my daughter’s home. Low noise and is very efficient! :)

We’re really grateful and appreciate you taking the time to share your feedback
