FAQs – Your Questions, Answered
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.
