Abstract
A self contained battery energized apparatus is mounted within the water tank of a conventional flush toilet to eliminate malodorous gases. Air from the toilet bowl is drawn through the stand pipe in the toilet tank into a housing to expose the air to UV radiation to produce ozone molecules that have an oxidizing effect on organic matter and the UV radiation serves as a germicide and a virucide. The ozonated and oxidized gases are exhausted through a carbon filter.
