What is CADR? (Clean Air Delivery Rate)
CADR is an established standard rating by the independent Association of Home Appliance Manufacturers (AHAM). It measures the efficiency of an air purifier, taking into account room size and the volume of clean air produced per minute. The removal of dust, pollen and smoke, which are the three most common indoor air pollutants, is rated. The higher the CADR, the better the air purifier.
