Summary:Provided is a cigarette filter and method of making the filter. The filter includes an adsorbent dispersed within the filter and a downstream plug of randomly-oriented fibers. The randomly-oriented fibers mechanically capture adsorbent particles entrained in tobacco smoke. One or more plugs of axially-oriented fibers may also be located upstream and/or downstream of the adsorbent, and are included in an amount sufficient to adjust the length of the filter.
