More Information
Summary:A smoking article includes a tobacco column, a wrapper and a carbon monoxide pump. The pump includes a separator, an adsorbent for carbon monoxide downstream from said separator and may include a catalyst for oxidizing carbon monoxide to carbon dioxide and venting holes adjacent to the adsorbent. In use, the carbon monoxide pump selectively diverts carbon monoxide from main stream combustion products, the separator impedes the entry of large molecules into the carbon monoxide pump, the catalyst at least partially oxidizes the carbon monoxide to carbon dioxide and the venting holes provide an alternative path for the diverted carbon monoxide and the oxidized carbon monoxide to check or reduce carbon monoxide inhalation by a smoker.
