What is a CADR?
Clean Air Deliver Rate (CADR) is an acronym and measurement developed by AHAM. CADR is the amount of clean air measured in cubic feet per minute that an air cleaner delivers to a room. It is tested on its ability to remove smoke, dust and pollen over time. This measurement is usually found on the back of the air cleaner packaging in the AHAM seal. Air purifiers without an AHAM seal have generally not been certified for CADR.
