Abstract
A filter material of a filter element configured for application in a smoking article may include a fibrous substrate material finished with a fiber finish composition. The fiber finish composition may be formulated to selectively interact with at least one target component of mainstream smoke drawn through the filter element during use of the smoking article to selectively filter the target component from the smoke. The filter element may include multiple filter segments. Each filter segment may include a filter material having a finish composition formulated to selectively interact with a different target component. The various filter segments may be combined and/or arranged to selectively filter the mainstream smoke to achieve desired characteristics. Each filter segment may be formed from the same fibrous substrate material.
