Abstract
A cigarette holder and filter cartridge combination including interconnected mouthpiece and cigarette holding sections which define a filter cartridge chamber and a filter cartridge, comprising a core of mixed absorbent and non-absorbent fibers and a cylindrical expandable paper wrapper, which when wet expands to fill the entire diameter of the filter cartridge chamber, thereby insuring that no smoke can reach the smoker by passing around the edges of the filter.
