    Abstract: A coin operated smoker's enclosure in the form of an upright booth with polycarbonate walls, aluminum framing and a hinged door. An air recirculation system provides treated air within the enclosure as well as carbon monoxide and smoke detection. An air exhaust system filters the air for particulate matter before exhausting it from the enclosure. The coin acceptor is wired to turn on the various electrically powered devices only when the appropriate coin requirements are met. An upright compartment in one corner of the enclosure houses all of the active components and is accessible from the outside of the enclosure.
