A toilet seat is provided on its underside with a suction tube having perforations that are in communication with the interior of the toilet bowl when the seat rests on the upper edge of the bowl with a sealing gasket arranged on the underside of the seat outwardly of such tube. When the seat rests on the upper edge of the bowl the suction tube is communicated with an electrically motorized suction blower unit through a mating face joint. An adjustable discharge tube extends from the blower unit into the bowl and is designed to extend under the trap and is adapted to be sealed off by the water normally present in the bowl so as to prevent sewer gases from coming into the bowl while causing odors from the bowl to be discharged through the normal drain passage of the bowl into the sewer line when the seat is down and the suction blower unit is activated by household electrical current through a switch unit.
