A method and apparatus for removing contaminants from contaminated air is accomplished by exposing an incoming air stream from a surrounding area to ultra-violet (UV) radiation to generate ozone in an ozone chamber of the system. The ozone chamber is configured to reduce air through-flow velocity and to provide time for the ozone to mix with the air and oxidize the contaminants. The air stream subsequently enters a germicidal chamber and is again exposed to UV radiation at a different wavelength to destroy bacteria and any ozone in the air stream thus resulting in sterilized air. The system may include various ozone and germicidal chamber configurations to increase residence time within these chambers. Further, the system may be configured for installation within a wall or ceiling, or for mounting on a ceiling fan motor for use with ceiling fans. |
