ABSTRACT:
An environmentally controlled commercial/public toilet designed to neutralize and confine contaminating agents such as bacteria, odors, vapors and other airborne particles inside the bowl by generating and maintaining a cyclone-type air circulation inside the existing bowl. A standard bowl (70a) with a housing (20a), and an air-trapping cavity (76) created inside the bowl (70a) by a detachable bowl-skirt (73a), confines the contaminating agents during toilet use and improves the efficiency of the air circulation. Sanitizer and odor conditioner cartridges are employed to neutralize the contaminating agents by releasing sanitizing and odor conditioning agents into the air flow circulated inside the bowl (70a). This invention is retrofitable to existing commercial/public toilets.
