A filter for smoking products contains a flavorant in a filter web which is a non-woven web comprising thermoplastic meltblown fibers of filaments that are present as fused agglomerates in a number fraction exceeding 33 percent and wherein a majority of fiber crosssings of agglomerates are weld points. The filter is obtained according to a preferred method by adding tobacco extracts to the filter web such that the filter web contains betweeen 10% and 110% tobacco extracts by weight of the filter web; adding glycerin or a glycerin -water mixture to the thus treated filter web; and forming the thus treated filter web into a rod.
