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 3500 and 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 3500 or an AirDoctor 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.
