*Harvard University Study cited by CDC recommends at least 4 air changes per hour to effectively remove viruses, bacteria, smoke, dust & pollen.
**CADR (Clean Air Delivery Rate) is an objective measurement for comparing air filter performance, based on its ability to remove particulate matter. The higher the number, the more effective it will be.
According to CDC guidance, CADR/cfm should be 2/3 of the total room size.
***Based on 24-hour daily usage.

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.

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.

Here’s a chart that should help:

Room Type Air Circulations Per Hour AirDoctor Unit
Bedrooms, living rooms, kitchens Circulates the air 4x/hour in 630 sq. ft. AirDoctor 3500
Bedrooms, nurseries, home offices Circulates the air 4x/hour in 305 sq. ft. AirDoctor 2000
Smaller rooms Circulates the air 4x/hour in 285 sq. ft. AirDoctor 1000
Extra large spaces, high ceilings, open concepts Circulates the air 4x/hour in 1,043 sq. ft. AirDoctor 5500

AirDoctor 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
