This is the air purifier that eliminates up to 99.9% of airborne germs and mold while projecting a starry night sky on a bedroom ceiling. It uses natural convection to silently draw airborne impurities including bacteria, mold, viruses, pet dander, dust mite allergens, and pollen, into its patented ceramic heating chamber and instantly destroys the microorganisms with 400º F heat. The sanitized air is cooled and recirculated into the room, providing a healthier breathing environment without producing noise or ozone, increasing room temperature, or requiring you to clean or replace a costly filter. The device remains cool to the touch and the star and moon projection can be set to red, blue, or green. AC plug. White. 13" H x 5 3/4" Diam. (2 1/2 lbs.)
