A cellulose acetate solution is filtrated with a filter medium formed of cellulose fiber.

The invention not only reduces the use amount of acetate fiber or cellulose acetate so as to reduce cost, but also remarkably improves the aesthetic quality of the paper filter stick cigarette.

At present, the main cigarette filtrational material is cellulose acetate tow and PP tow. The development of paper filter tip using sepiolite as cigarette filtrational material is discussed.
