This is the WiFi-enabled purifier that changes the air in a 280' sq. room five times per hour, eliminating dust, pollen, and other allergens to create a healthier breathing environment. This superior clean air delivery rate is achieved by applying an electrostatic charge to particles, which attracts them to the polyproylene fibers of the anti-microbial HEPA filter. This process snags more than 99.9% of pollutants, including mold spores, pet dander, and tobacco smoke, all while emitting decibel levels equivalent to the hush of rustling leaves. The intelligent device can be manually controlled via an intuitive digital panel. It also connects over WiFi with a smartphone running a free app, which can control settings remotely and monitor outdoor air quality in your location. With three fan speeds and a quiet night mode. Filter provides six months of continuous use. 21" H x 17" W x 8" D. (22 lbs.)
