CADR: refers to the clean air volume, that is, the total amount of clean air output per unit time after being filtered by the purifier, in m/h, including particulate matter CADR and formaldehyde CADR. The CADR value is the volume of clean air provided by the air purifier per hour, which measures the purification efficiency of the air purifier. For example, if the CADR of particulate matter is 500 m/h, it means that 500 cubic meters of air can be cleaned of particulate matter in one hour. In theory, the larger the CADR value, the faster the purification speed and the larger the applicable room area. There is a calculation formula: applicable room area = CADR value * (0.07-0.12). For example, the CADR of an air purifier is 600 cubic meters per hour, and its applicable area is 600*0.07 or 0.12=42-72 square meters.
