ABSTRACT:
A filter cartridge assembly for filtering tars from tobacco smoke is described, said assembly comprising a cylindrical sleeve and an inner filter core member, the inner surface of the cylindrical sleeve and the outer surface of the core member defining a smoke passageway. One end of the sleeve is formed with an obstruction having a restricted inlet passage therethrough, the other end being essentially open for receiving the filter core member therein. A pair of stand-off contacts is provided on one end of the core member, said contacts projecting from an impingement surface, and a cylindrical plug having a restricted outlet passage is formed on the opposite end. When the core member is assembled within the sleeve, the plug end thereof is positioned in sealing relating to the open end of the sleeve and supports the filter core member therefrom. The cross sectional area of the restricted outlet passage is carefully selected to control the flow of smoke through the assembly to control the level of filtration and affect the quality of taste.
