This is the home air sanitizer that eliminates viruses, mold, and germs in the air and on surfaces. The device uses a similar technology developed by NASA for purification aboard space shuttles: ultraviolet light inside the device combines with a nickel catalyst to emit safe catalytic molecules that destroy up to 99% of mold and bacteria on surfaces. A fan draws in airborne impurities and the UVC bulb—the same technology used to sanitize hospital surfaces—instantly kills airborne allergens, viruses, and odor-causing volatile organic compounds. About the size of a table lamp, the air and surface sanitizer sets up unobtrusively on a desk or table and cleans up to 3,000' sq. ft. Its filterless design eliminates the need for costly filter replacements and the fan generates only a whisper-quiet hum. 15 3/4" H x4" sq. (5 lbs.)
