This is the air purifier that eliminates up to 99% of airborne viruses, mold, and germs without making a sound. When placed in a room’s optimal location, the device uses natural convection to silently draw airborne particles into its patented ceramic heating chamber where they are destroyed using 400° F heat, confirmed by an independent laboratory as a proven technology that also destroys bacteria and allergens such as pet dander, dust mites, and pollen. Sanitized air is cooled and recirculated into a room, providing a healthy breathing environment without producing ozone or the need for filter replacement. Quickly and efficiently replaces the air in a standard size room in about four hours, remains cool to the touch, and will not raise room temperature. For rooms up to 550' sq. White. 10 1/2" H x 8 1/2" Diam. (3 1/2 lbs.)
