ABSTRACT:
Apparatus for removing and preventing escape of noxious fumes from a commode bowl has a plurality of circumferentially arranged radially inwardly directed air inlet passages adjacent the bowl rim for the intake of ambient air surrounding the commode. A plurality of circumferentially arranged radially outwardly directed outlet passages are positioned below the inlet passages for suction withdrawal of the noxious fumes mixed with the incoming air. The inner edge of the commode opening between the inlet and outlet passages is configured to create turbulence within the bowl to mix the fumes therein with the incoming air.
