A toilet bowl ventilating device that is entirely contained within a toilet seat of standard dimensions which immediately vents to the outside noxious human elimination odours. The toilet seat contains a posterior portal vent that is positioned adjacent to an identical sized vent in the lateral tube, all of which is fastened to the toilet bowl by means of the standard bolts. The lateral tube connects to an elbow, on either side, with the opposite side being capp ed off, which then connects to a pipe which enters behind the wall, which in turn connects to a n air duct channel behind the bathroom wall and connecting to the exhaust fan that expels the odours to the outside. The underside of the toilet seat has a circular gasket of soft rubber that forms a perfect air seal when weight is applied, thus forming a perfect air seal.
