This is the air purifier that uses UV light to destroy the influenza virus as well as harmful allergens, impurities, and bacteria. Despite its slim size, the powerful purifier eliminates 99% of airborne germs in an 800' sq. room through a three-phase cleanse every 20 minutes. After a fan draws air into the tower, baffles slow its speed to ensure a thorough treatment. Cleared by the FDA for the medical-grade destruction of bacteria, the device uses ultraviolet rays—the same technology trusted for sanitation in the health care industry—to disrupt the seasonal flu virus, H1N1, and other causes of respiratory illness, while a titanium-dioxide coating breaks down odor-causing volatile organic compounds. A carbon-treated screen then traps dust, pet dander, and other allergens to create a cleaner, healthier environment. The purifier emits no dangerous ozone, and its UV cartridge lasts almost 9,000 hours without needing replacement. Plugs into AC. 32" H x 10 1/2" W x 12 1/2" D. (14 3/4 lbs.)
