Abstract

A filter for smoking articles includes two sections, a first section comprising a longitudinally extending opening surrounded by smoke impervious material and a second section comprising a core having a high-pressure drop material, a circumscribing annulus having a lower pressure drop filter material than the core. The first section is generally adjacent to the tobacco section of a cigarette at a first end and is spaced from the second section. Moreover, the invention comprises ventilation holes circumscribing the space or gap between the first and second section or circumscribes the second section.
