A smoking article filter comprising: a filter material having a circular cylinder shape with first and second end surfaces and a side surface, and including a corrugated film with ridge portions and valley portions arranged alternately, the ridge portions and valley portions extending from the first end surface to the second end surface to form a plurality of air flow paths that allow air to flow from the first end surface to the second end surface; a plurality of particles arranged in the air flow paths; and a filter wrapping paper wrapping the filter material such that the side surface is covered with the filter wrapping paper.

The invention relates to an additive releasing material comprising a carrier material having on its surface one or more additives, the additive releasing material having a desorption temperature selected to allow controlled temperature-dependent release of the additive(s). The invention further relates to filters and smoking articles including such additive releasing materials, and to methods for preparing the additive releasing materials.

The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. For example, some aerosol delivery devices of the current disclosure include a reservoir having a liquid aerosol precursor composition, an electrical heater in fluid communication with the reservoir and configured to vaporize the liquid aerosol precursor composition to form an aerosol, and a filter operatively arranged relative to the electrical heater such that at least a portion of the formed aerosol passes therethrough, the filter being configured to selectively bind one or more undesirable impurities.
