Designed by NASA scientists, the Airocide purifies toxins in the air that can worsen symptoms of asthma or allergies. Each Airocide unit incorporates a reaction chamber that contains thousands of tiny glass rings coated inside and out with titanium dioxide (TiO2). With the help of a high-intensity light, the TiO2 produces hydroxyls. When airborne organic molecules are drawn in and make contact with those hydroxyls, the carbon bonds in those molecules are broken. Thus it inerts virtually any organic compound passing through its reaction chamber. The hydroxyls are tethered to the TiO2 surface, and can't escape from the chamber. In this process, no ozone or other gases are released, no chemical additives are used (besides the already-present TiO2), and nothing has to be cleaned out. According to the Airocide company, the purifiers are almost 100 percent effective at neutralizing biological pollutants like mold, fungi, pollen, dust mites, viruses and bacteria, along with volatile organic compounds (VOCs) that are given off from materials such as carpeting and paint. The Airocide purifier will set you back $799.
