NOVELTY - Composite filter stick comprises a first acetate fibre filter stick and adding MOF-199, graphene modified active carbon, second acetate fibre filter stick combination of linoleic acid modified nanometre silicon base oxide, where the most adjustable aperture of the MOF-199 is 0.9-1.1 nanometer, the pore ratio of 0.8-2 nanometer aperture in the graphene modified active carbon is 80%. USE - Composite filter stick used for reducing propionaldehyde in cigarette smoke, where the cigarette is a cigarette-type cigarette and a cigarette type cigarette. ADVANTAGE - The composite filter stick reduces propionaldehyde in cigarette smoke, which can reduce the irritation of the cigarette, and does not affect the whole fragrance and style characteristic of cigarette, improves the oral flexibility, comfort, and improves the smell absorbing quality. The adding material is non-toxic and harmless, the source is sufficient, the manufacturing is convenient and the cost is low.
