* Harvard University Study cited by CDC recommends at least 4 air changes per hour to effectively remove viruses, bacteria, smoke, dust & pollen.
** CADR (Clean Air Delivery Rate) is an objective measurement for comparing air filter performance, based on its ability to remove particulate matter. The higher the number, the more effective it will be. According to CDC guidance, CADR/cfm should be 2/3 of the total room size.
*** Based on 24-hour daily usage.
