Abstract: A toilet ventilation system which may be produced as either a permanently installed system or a portable system which may be moved from place to place with relative ease. In the portable system, odors are collected into either an easily installed and removed collection collar which fits within the toilet bowl ring, or ducts within the toilet seat, and then vented through flexible tubing, by means of an impeller fan, to a point outside the room. In the permanent system, odors are collected either through the seat ducts or ducts formed within the rim of the toilet bowl. Venting to the exterior of the room is then accomplished through ducts permanently installed in the structure and an impeller fan within the duct system.
