摘要：
Provided are filters including at least one impervious additive containing tube. A barrier, such as a liquid barrier, seals each end of the tube so as to contain additives, such as a liquid additive, within the additive containing tube. The one or more additive containing tubes are inserted into filters for smoking articles. Drawing action during a puff causes breach of the barrier and release of the additive into the surrounding filter material.
