ABSTRACT:
A portable ventilation system includes an air filter unit located remotely from a toilet and having an air duct extending from the filter unit to the toilet to exhaust and deodorize air from the toilet bowl. The filter unit includes an impeller which moves air through charcoal type filter media and exits the filter unit through a plurality of apertures in the bottom of the unit. An air duct is slidably journaled between the toilet seat and toilet bowl rim upper surface at the rearward end of the seat, and is connected to the filter unit to draw air from the toilet bowl and through the filter unit. A control unit is electrically connected to the filter unit and includes a switch to activate the impeller in the filter unit to operate the ventilation system. In one embodiment of the invention, a sensor is mounted in the control unit so as to sense the presence of a person on the toilet to automatically activate the filtration system.
