Abstract (en)
A filter for a cigarette comprises several filter sections where filtering materials (2) are wrapped individually with winding papers (3), a shaping paper (5) for wrapping the filter sections integrally, and a chip paper for covering the shaping paper in order to produce a cigarette through connection with the cigarette part. Active carbon (41) and silica/alumina (42) are contained as an adsorbent in at least one of the filtering material and the air gap between the filtering materials.
