<p>In the present invention a germicidal ultraviolet light apparatus is mounted within a specially designed filter element that is designed to fit within the standard filter access ports for re-circulating (HVAC) air systems. The ultraviolet light source is positioned to project ultraviolet light towards surfaces found within the filter area and components found downstream of the filter in the HVAC system for the purpose of sterilization and maintenance of these areas. Preferably, the filter elements contain a special tackified air filtration media designed to increase the reactivity of the UV light within the filter area. In addition, the present invention includes a safety interlock mechanism that cuts power to the UV source when the filter element is removed from the re-circulating air system. Finally, the present invention involves various sources of supplying power to the UV apparatus for installation flexibility.</p> |
