ABSTRACT:
Tobacco smoke filters wherein the products have an elongated hollow inner member overwrapped with a conventional plug wrap, with an intermediate member interposed therebetween. The intermediate member is comprised preferably of a filtering material different from that which forms the inner member so as to provide selective filtration through the two layers of filtering material, the intermediate member functioning to remove larger particles of undesirable material so that the interstitial spaces of the inner member are not clogged thereby. Moreover, the presence of the intermediate member provides a smooth outer surface for attaching a conventional plug wrap without the need for an internal glue line.
