| titleOfInvention | CIGARETTE FILTER. |
| abstract | A cigarette filter that includes a multi-section filter that reduces the level of predetermined smoke constituents. The filter (130) consists of a fibrous filter plug (132) located at the end of the mouth cigarette, a section (136) containing a selective adsorbent material, and a section (134) containing a general adsorbent material. The selective adsorbent material, such as a surface-functionalized phenol-formaldehyde resin matrix primarily with primary and secondary amine functional groups, removes specific constituents of tobacco smoke. The general adsorbent material, such as activated carbon, is preferably capable of adsorbing a range of chemical compounds without a high degree of specificity. Structurally, the fibrous filter plug, the selective adsorbent section and the general adsorbent section are coaxially aligned in tandem. |
