Abstract

Provided is a cigarette filter and method for potentially reducing particle breakthrough. The filter 10 includes an adsorbent 12 including adsorbent particles dispersed within the filter and a plug 14 of electrostatically charged fibers. Preferably, the adsorbent is activated carbon. In a preferred embodiment, the electrostatically charged fiber material is located downstream of the activated carbon. Preferably, the electrostatically charged fiber material has permanent electrostatic charges that electrostatically capture the carbon particles to reduce carbon particle breakthrough. In an embodiment, the electrostatically charged fiber material is randomly oriented so as to mechanically capture particles entrained in mainstream smoke. Also provided are a method of making the filter, a smoking article incorporating the filter, a method of making the smoking article and a method of treating mainstream tobacco smoke.
