This is the air purifier that uses three filters and an ultraviolet light to trap and eliminate most germs. A washable pre-filter captures large dust particles while a second filter removes particles such as dust mites, pet dander, and pollen from the air. It also has an ultraviolet bulb that emits safe UV-C light—the same technology trusted to sanitize hospital instruments—that helps reduce germs, and a photocatalyst filter that removes 90% of volatile organic compounds (VOCs emitted by household paint and carpet fumes). Also filters cigarette smoke. With three speed settings. For rooms up to 300' sq. AC plug. Black. 25 1/4" H x 8 3/4" W x 7 1/2" D. (9 1/2 lbs.)
