ABSTRACT:
A reaction chamber is filled with a fine fibrous material capable of holding powdered anatase titanium dioxide. Embedded in the fibrous mesh is a source of ultraviolet light that is used to photo-excite the titanium dioxide. Air containing carbon monoxide is passed through the reaction chamber, and carbon monoxide is oxidized to carbon dioxide which then passes out of the filter. An alternative embodiment is a rectangular plate several feet square containing fibrous material containing titanium dioxide. Ultraviolet light impinges on the fibrous material photo-exciting the titanium dioxide. When air from an HVAC system is passed through the filter, carbon monoxide is oxidized into carbon dioxide and thus effectively removed from the air. Ultraviolet light can alternatively be supplied to the filter via lossy optical waveguides or fiber optics. These waveguides may be coated with titanium dioxide or the titanium dioxide may be separately suspended in the filter.
