Summary:- 24 A cigarette filter (14) for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter (14), primarily comprises an activated 5 carbon fiber filter section (16) including a bundle of activated carbon fibers (24). Particulate absorbent materials such as granules, beads or course powders (42) may be dispersed amongst the activated carbon fibers (24) to aid in removal of the gas phase constituents. Additionally, the activated carbon fiber filter section (16) may be used in combination with a separate bed or beds of particulate absorbent material 10 (42). In one embodiment, the activated carbon fibers (24) are positioned within a helical groove (116) on the outside of a threaded rod (114) within the activated carbon fiber section (16). Relatively smaller amounts of activated carbon fibers (24) produce the same smoke constituent reduction as larger amounts of particulate absorbent material (42). 24/12/09,va 18440 p24 speci.doc,24 Ac0bet I- .(12 2 -2- lA6
