<p>The adsorbing surfaces (2) placed in the cigarette filter (1) form a cooling surface for the smoke that is still warm. When the smoke contacts with the adsorbing surfaces (2) which are colder than itself, it is suddenly cooled and the toxic substances laden in the smoke in the form of a suspension, bind to the surface of said adsorbing surface (2), remain on them, thus their delivery to the respiratory tract is avoided.</p> |
