ABSTRACT:
A portable smoking room having a flexible enclosure defining a room detachably mounted on a frame is provided. A duct is detachably mounted to the frame for transporting smoke laden air within the flexible enclosure outside of the flexible enclosure. A fan detachably mounted to the duct creates negative pressure within the flexible enclosure such that smoke laden air within said flexible enclosure may be drawn out though the duct and ambient air from outside may be drawn in through a plurality of air intake apertures in the flexible enclosure. The frame of the portable smoking room may be disassembled when the enclosure and the duct are detached from the frame such that the flexible enclosure, the frame, the fan, and the duct may be transported and reassembled at another location.
