Abstract

"FILTRO PARA CIGARRO, E, CIGARRO COM FILTRO é proporcionado um filtro para um cigarro e um cigarro com filtro que torna a sensação do fumar mais suave sem o sabor e aroma de cigarro originais serem alterados. O filtro para cigarro tem uma haste de filtro (8) tendo uma superfície permeável ao ar, e de 3 a 12 passagens axiais (12) na haste (8). Estas passagens (12) são distribuídas num anel dotado de um diâmetro de 50 a 70% daquele da haste e tem um diâmetro de 0,1 a 0,7 mm. A parede das passagens axiais (12) tem permeabilidade ao ar. Ao fumar, o ar de ventilação introduzido nas passagens (12) dilui a corrente de fumaça do cigarro.
