Everyone wants clean air indoors. In fact, indoor pollution may be more of a problem in many areas than outdoor air pollution. So companies are building better indoor air purifiers. One company, NanoTwin Technologies, has patented NanoTube as the active component behind their NanoBreeze Air Purifier. The tube is wrapped in a fiberglass mesh coated by a layer of titanium dioxide crystals that measure 40 nanometers in size. When switched on, the NanoTube radiates UV light that charges the crystals to create powerful oxidizing agents that destroy airborne germs and pollutants circulating over the tube's surface.
