摘要：
A filter for a smoking article comprises a first flow path 13 through the filter 15, a second flow path 14 through the filter, the second flow path being disposed around the first flow path, and selecting means for allowing flow selectively through the first and second flow paths or an adjustable proportion of the first and second flow paths. Alternatively first and second half cylindrical parts 53, 54 may define first and second flow paths. The selecting means 18, 57 may include a rotatable part. At least one of the first and second flow paths may contain an additive release component in the form of microcapsules 56.
