ABSTRACT:
An air tight cylindrical U shaped or angled tube that can be assembled and disassembled. The U tube is constructed of polystyrene or another non flammable material. A fan unit (12) pushes fresh air into one end of the combustion chamber tube (300). A cigar or cigarette is held within the combustion chamber tube 300 with a stainless steel support (10). The smoking medium is ignited via an ignition access port (15). One can inhale smoke via a one way inhalation valve (9). Then, one can exhale secondary smoke into a filtration chamber tube (100) via a oneway exhalation valve (6). Primary and secondary smoke are filtered within the unit by an activated carbon filter (5) prior to returning to the outside environment.
