Abstract: A removable ventilation and filtration apparatus for a conventional flushing toilet having a rim and a seat secured to said rim. The configuration allows for the intake of malodorous gases and the elimination of such odors by means of an elongated opening, situated between a gap commonly found between a toilet seat and rim, and a down-flow active filtration assembly utilizing a pressure-based air treatment and flow configuration by encompassing a switch-activated exhaust fan on at least one side of a deodorizing filter, thereby creating a space of negative pressure that intakes foul air through the elongated opening. The foul air is thereafter pulled into and through the deodorizing filter and an anti-microbial filter, and subsequently cleansed air is pulled therefrom. The cleansed air is then released into the immediate vicinity through an exhaust-opening. The apparatus is secured to the toilet bowl by use of an adjustable hanging bracket.

Abstract: An odor evacuation system for use in connection with a toilet having a toilet bowl with a rim has an inlet assembly configured for detachable mounting on the rim of the toilet bowl. A nozzle of the inlet assembly has an opening for admitting air from the toilet bowl, the nozzle being configured to fit into a gap between the rim of the toilet bowl and a toilet seat. An outlet assembly is fluidly connected to the inlet assembly. The outlet assembly has an outlet opening, a suction fan positioned upstream from the outlet opening and a filter member mounted upstream of the suction fan for scrubbing air admitted through the inlet assembly of objectionable odors. A flexible conduit is mounted between the inlet assembly and an outlet assembly for directing air from the inlet assembly to the outlet assembly.
