CA 2040635

A novel cigarette smoke filter element is provided which achieves an increased removal of tar from cigarette smoke while retaining a higher flavour level than is achieved using conventional filter materials. The filter comprises an elongate cylinder of microfine fibers which is closed at the upstream end of the filter element and tobacco smoke filter material located both externally and internally of the cylinder of microfine fibers. A tobacco smoke flow path blocking means is provided at the downstream end of the filter element to permit filtered tobacco smoke to pass from the filter element only from the tobacco smoke filter material located internally of the cylinder of microfine fibers.
