ABSTRACT:
An improved apparatus for ventilating and purifying the unpleasant bathroom odors arising from the bowl of a water closet type commode. The apparatus has a seat and lid commonly mounted upon pintles for swinging relatively to one another and to the bowl. The lid carries a tubular shutter valve, which is closed except when the lid is open, for sealing the filter and motor elements carried within a sealed compartment in the lid from air inlets in the seat. The seat has a concealed air inlet opening downwardly at the rear edge of the bowl. Water cannot traverse the shutter valve and injure the filter or motor.
