CADR Rating


CADR (Clean Air Delivery Rate) rating is a measure of the effectiveness of air purifiers in removing smoke, dust, and pollen particles from the air. It is determined by the Association of Home Appliance Manufacturers (AHAM) and is based on the volume of air that is cleaned per minute and the percentage of particles that are removed from the air. The higher the CADR rating, the more effective the air purifier is at removing airborne particles. CADR ratings are important for individuals who suffer from allergies or respiratory problems, as well as for those who live in areas with high levels of air pollution.
