Based on testing of SARS-CoV-2 conducted in laboratory conditions, using a 13 cubic foot chamber to protect scientists from exposure. Not proven to prevent COVID-19. Performance was measured after 10 air exchanges passing through the air purifier operating at its minimum fan speed and with plasma ion technology on. Actual results of treated air may vary, depending on usage environment (temperature, humidity, room size and shape, nature and number of particulates in air, etc.), placement of the unit, and product usage (operation duration, operation mode, etc.). Best results with continuous use.
