The smoking article comprises a tobacco rod (12) connected to an air ventilated compound filter having two abutted filter segments, a rod end segment (20) with a passage (26) therethrough and a mouth end segment (22). The pressure drop of the abutment interface (25) between the segments is selected to be in a range of from about 10 mm to about 100 mm water gauge.
