Air Cleaner CADR Room


The CADR value is the main index used by international authoritative organizations to evaluate air purification efficiency, which is short for Clean Air Delivery Rate. CADR: is the ratio of clean air output from air purifiers tested by the American Association of Home Appliance Manufacturers (AHAM) in accordance with strict testing standards. The higher the CADR value, the higher the purification efficiency of the purifier. The performance of an air purifier is mainly determined by the clean air delivery ratio (CADR value).
