Abstract

Disclosed is a filter element adapted to be incorporated into a filter cigarette. The filter element comprises filter material, particles of a magnetized adsorbent, and at least one magnetic substrate. During smoking of a cigarette comprising the filter element, the at least one magnetic substrate can filter (i.e., magnetically attract and trap) the magnetized adsorbent particles or fragments thereof within the filter element.
