What does CADR stand for?Updated 7 months ago
CADR stands for Clean Air Delivery Rate. In short, it is the volume of filtered air. This is a way for you to compare the amount of air cleaned from air purifiers. There are three sizes of particles measured. They each indicate the air purifier's ability to remove the smaller particles (smoke) up to larger particles (pollen). Smoke CADR (0.09 - 1 micron) Dust CADR (0.5 - 3 microns) Pollen CADR (5 - 11 microns)
