There are 3 pollutants that CADR measures, which are representative of different size particles, and they are: POLLEN, which represents larger particles (20 microns) DUST, which represents medium sized particles (5 microns) and SMOKE, which represents some of the smallest particles (0.1-1 microns). CADR helps tell you how much of a particular contaminant is removed from the air within a specific period of time, and it creates an objective rating that allows consumers to compare one air purifier to another based on standardized testing. According to CDC guidance, CADR/cfm should be 2/3 of the total room size.ĬADR stands for Clean Air Delivery Rate.
