20110171080 | UNITIZED PHOTOCATALYTIC AIR STERILIZATION DEVICE - A UV photocatalytic air purifier/sterilizer in which the multiple limited-lifetime components (such as the UV light, UV light electronics, and catalytic portion) of a photocatalytic UV air purifier/sterilizer are packaged together to form a single, handheld, unitized package, designed for easy insertion and removal into an air purifier. The invention may be configured enable maximum air flow through the photocatalytic portions of the device, thus further improving air cleaning efficiency by allowing many volumes of room air to be recirculated through the device and cleaned/purified/sterilized over the course of a day. In a preferred embodiment, the device may package a series of stacked TiO | 07-14-2011 |
