Abstract
L'invention concerne une section filtre pour un article à fumer. La section filtre comprend une forme cylindrique et s'étend d'une extrémité distale à une extrémité d'embout buccal, créant ainsi une voie d'écoulement pour au moins un fluide. La section filtre comprend en outre au moins un matériau filtrant et une cavité. La cavité est entourée par le matériau filtrant. Selon l'invention, la cavité comprend au moins deux compartiments en communication fluidique avec la section filtre et bloqués par une barrière cassable commune. Chacun des compartiments comprend des composants pour un mélange ayant un caractère hydrophile pour absorber l'eau provenant de la voie d'écoulement de fluide. Un premier compartiment comprend au moins un premier composant et un second compartiment comprend au moins un second composant. Le premier composant comprend un produit de tabac dispersé et le second composant comprend un matériau absorbant les fluides.
