ABSTRACT:
A cigarette holder completely encloses the lit end of a cigarette providing purification for both sidestream smoke and mainstream smoke. It has two concentric tubes with the lit cigarette placed in the inner tube and purifying agent placed in the volume between the inner tube and the outer tube. A chimney effect is produced wherein air flows through an air port past the lit cigarette to keep it burning. The sidestream smoke passes through the purifying agent and is discharged into the environment. The filter tip of the lit cigarette extends through a mouthpiece and the smoker exhales smoke through openings in the same mouthpiece. The mainstream smoke passes through the same purifying agent, in a direction opposite to the flow of the sidestream smoke, and is then discharged into the environment.
