The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. 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.

There is provided a composition for inclusion in a smoking article comprising an ion exchange resin and additive particles comprising an additive on the surface of the ion exchange resin. There is also provided a smoking article filter element comprising this composition, a smoking article comprising this smoking article filter element or this composition. A method of preparing a composition comprising an ion exchange resin and additive particles comprising an additive is also provided, the method comprising the deposition of additive particles onto the ion exchange resin from the solid and/or liquid phase of an aerosol.

The present invention relates to improvements in filters for use in smoking articles such as cigarettes, cigars and cigarillos. The improvements, particularly but not exclusively, relate to filter capabilities and to the manufacture of such filters. In one example, a filter for a smoking article comprises a first fibrous filter material having an average fiber denier in the range 7 to 9 and a second fibrous filter material having an average fiber denier of below 7. The application also describes a filter for a smoking article comprising various other filter arrangements including absorbent and/or adsorbent materials.

Smoking articles which involve the use of amphiphile-modified sorbents are disclosed. The amphiphile-modified sorbent has at least one amphiphilic compound bound to an inorganic molecular sieve substrate. The amphiphile-modified sorbent selectively removes certain constituents from cigarette smoke, while maintaining other constituents, such as those that contribute to flavor. Methods for making cigarette filters and smoking articles using amphiphile-modified sorbents, as well as methods for smoking a cigarette containing an amphiphile-modified sorbent, are also provided.
