Abstract
Abstract The seat of a toilet stool has an air chamber which receives odorized air. It is in communication with a passageway in the seat attaching hinge. The hinge passageway communicates with a filter wherein air is deodorized and passed into the atmosphere. Blower apparatus therein moves normally odorized air through filtering material. The seat hinge passageway and the filter are connected by a conduit. Pressure exerted on the seat activates the blower apparatus.
