ABSTRACT:
The toilet seat of this invention has a hollow central portion therein with holes in the front and rear of the inner lateral sides through which air is drawn inwardly. Vacuum hoses are connected to the hollow central portion of the toilet seat and lead to a vacuum pump mounted near the toilet. The vacuum pump sucks the odor-laden air from the toilet seat area and blows it to the outside through an expulsion tube.
