- a. an upper sitting surface;
b. an interior cavity within said seat and below said upper sitting surface;
c. a toilet seat interior side wall; and
d. a plurality of orifices along said side wall in which said interior cavity is accessed. - The toilet seat interior cavity has an outlet constructed and arranged to receive an outlet hose connector.
- Also contemplated is a system for eliminating odor in and around a toilet bowl wherein the toilet seat of the present invention is connected to an exhaust hose connected. The hose connects to the seat outlet on a first end and to a component box on a second end.
- The component box, in one embodiment, has a filter therein. In another embodiment, the component box has a fan inside.
- The fan connected by the house to the toilet seat, draws air into the toilet seat orifices such that malodorous air travels through the orifices, into the seat cavity, out of the seat cavity and into the exhaust hose.
