The photocatalytic action of titanium dioxide and the anti-odor activity of undecylenic acid or its compounds are combined in an atmospheric scrubbing or renewal system. The invention consists in placing a filter impregnated with these two substances and exposed to a natural or artificial source of ultraviolet radiation in the path of the air.
An ultraviolet disinfection (UV) system for gases including a UV light-ready gas purifier having at least one portal in the gas purifier for receiving UV light input from a UV light source, which is removably connected to the gas purifier via a connector at the portal, and positioned to provide a focused, controllable UV light output that has at least one UV dose zone for providing effective sterilization of microorganisms and disinfection within an interior of the gas purifier. The light source is positioned within a housing that is external to the gas purifier and capable of being connected thereto via optical connectors, such as fiber optic transmission lines. A method for UV disinfection of the interior of gas purifiers is also included in the present invention.
