摘要：
A filter mouthpiece 12 for a smoking article comprises a rod end portion 14 having a tube 24 extending axially therethrough and a mouth end portion 16. The tube is open at each end and has perforations 26 in its wall. The peripheral surface of the filter mouthpiece is rendered air permeable in at least one discrete area by means of perforations 28 in an impermeable tipping 22, to admit air to the filter. When attached to a tobacco rod 10 this filter mouthpiece provides a substantially constant dry particulate matter delivery throughout the smoking of the article.
