FIELD: tobacco industry.
SUBSTANCE: cigarette filter contains a filtering rod containing staple fibres based on compound ether of cellulose, cellulose mass and an alkali metal salt and a water-soluble anionic polymer. The content of alkali metal in such filtering rod is equal to 2 - 100 mcmol per 1 g of the filtering rod.
EFFECT: in the proposed cigarette filter sufficient strength in a dry condition and sufficient destruction in a wet condition are combined; such filter is destroyed in a wet condition during a very short period of time.
