Abstract (en)
[origin: WO2009080368A1] Provided is a cigarette filter (10) and method of making the filter. The filter (10) includes an adsorbent (12) dispersed within the filter (10) and a downstream plug (16) of randomly-oriented fibers (14). The randomly-oriented fibers (14) mechanically capture adsorbent particles entrained in tobacco smoke. One or more plugs (25) of axially-oriented fibers (30) may also be located upstream or downstream or both of the adsorbent (12), and are included in an amount sufficient to adjust the length of the filter (10).
