To freshen air in the bathroom we have traditionally, use air sprays, lit candles opened windows, installed, ceiling fans and lately with the use of different kinds of suction systems that suct odor under the seat. Most of these suction systems are expensive unsightly in, appearance, especially the hose and tubing on top of the seat, scary looks and difficult to construct. In contrast with my invention seat suction system at the bottom is shape like a horseshoe hollow space with gradually increasing in depth to enlarge the flow capacity until suct air reaches the rectangular ducting in shape. This is cheaper, simplier and has a better appearance.
