Additional filter device for cigarettes with fiber filter

Abstract

Additional filter device for cigarettes with fiber filter to reduce the passage of tar into the smoker’s mouth, thus reducing toxicity due to the combustion of the paper/tobacco mixture of the cigarette. Includes a laminar cylindrical body coaxially located between two sections of the cigarette fiber filter. The longitudinal middle area of the cylindrical body houses a transverse laminar disc having three holes, through which the smoke generated by the tobacco combustion and wrapping paper passes. The holes of the disc are equidistant from each other and are placed in a triangular configuration. The proximal and distal ends of the cylindrical body have annular flaps, which separate the disc from the fiber filter sections, and formed between these flaps and the disc, respective first and second air chambers where a high percentage of toxic substances contained in the smoke generated during the combustion of tobacco and wrapping paper is retained.
