1. What is CADR? CADR stands for “Clean Air Delivery Rate,” which indicates the volume of filtered air delivered by an air purifier. CADR ratings show the effectiveness of how efficient the air purifier is at capturing fine particles from things like tobacco smoke and plant pollens from the room. Clean Air Delivery Rate From air cleaner to air cleaner, compare the CADR numbers. First look at suggested room size. Then refer to the Clean Air Delivery Rate (CADR) numbers. The higher the number, the faster the unit filters the air. 2. What is CFM and CMH of CADR? 1 CFM=1.71CMH 3. TROUBLESHOOTING GUIDE A. Unit shuts off unexpectedly or does not operate.
