Abstract

A filter adapter for use with a waterpipe comprises a closure cap with a cutout; a spigot tap with a cylindrical sleeve, an integral port, a cylindrical base with male threads, the port providing communication between the sleeve and the base; and a ventilated filter cartridge containing a filter medium, preferably silica gel granules. The closure cap is frictionally engaged over the smoke passage of the waterpipe. The spigot tap, having been threaded into the cutout of the closure cap, effects the seal between the spigot tap and the smoke passage. The diameter of the sleeve on the spigot tap is a predetermined diameter to allow frictional insertion of a filter cartridge. A ventilated filter cartridge preferably containing silica gel granules as a filtering medium is frictionally engaged into the open end of the sleeve. The spigot tap provides communication between the filter cartridge and the smoke passage. In the second embodiment, the closure cap has a cutout with a predetermined diameter to fit a compressible bushing with an axial bore. The bore is a predetermined diameter to provide frictional engagement of a hollow tube with a sleeve insert. The sleeve insert has a predetermined diameter to frictionally engage a ventilated filter cartridge filled with a filter medium, preferably silica gel granules. In both embodiments, the user inhales smoke which is drawn through a passage containing water and ice. The filter cartridge purifies smoke consumed from the smokable substance, resulting in the users' experience being more pleasant, satisfying and beneficial.
