No, the Clean Air Delivery Rate (CADR) is a lab-tested measurement of the number of contaminants a purifier can remove from a sealed room. This is a measurement of cleaning efficiency. Cubic Feet per Minute (CFM) is a measurement of the volume of air a purifier can move, not its cleaning performance. However, CFM does affect the clean air delivery rate (CADR), where a higher CFM means more cleaning effectiveness.
