ABSTRACT:
A toilet ventilation generally comprised of an inventive toilet seat, a pre-filter, a water bleed-off means, an exhaust tubular member, and an electrically powered air extraction means. The inventive toilet seat rests directly on a toilet bowl rim and contains a plurality of ducts within the toilet seat. The series of ducts guide the odorous air toward the air extraction means. A water bleed-off means is implemented to trap moisture suspended in the odorous air and to prevent the moisture from entering the exhaust tubular member and the air extraction means thereby increasing the expected life of the ventilation system.
