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.

Abstract: Rotatable circular plates are stacked apart to form thin air layers therebetween. Rotation of the circular plates moves air over an air treatment material: catalyst or adsorbent. In one embodiment, the air treatment material is affixed to the surface of the circular plates. In another embodiment, the circular plates are formed from the air treatment material. The increased velocity of air relative to the circular plates causes separation of laminar flow, promotes boundary-layer turbulence near the plate surfaces, and promotes propagating stall in the air layers. These phenomena enhance the contact between the flowing air and the air treatment material.
