A filter element for use in a smoking article includes a filter material comprised of paper sheet having a crimped three-dimensional structure. Polyethylene glycol, triethyl citrate, or triacetin is interacted with the filter material to increase the selective removal of semi-volatile compounds from mainstream smoke being drawn through the filter element, over the filter material alone. An associated method of making a filter element for use in a smoking article is also provided.

The present disclosure relates to a filter for a smoking device, such as, but not limited to, a water pipe. The filter includes a body that is positionable over a mouthpiece of the smoking device, to filter impurities from smoke drawn therethrough, and a base that secures the body over the mouthpiece such that smoke is drawn therethrough, prior to inhalation by a user. The body can include one of more filtration layers, such as a first layer formed from a material selected to filter carcinogens and other impurities from the smoke prior to inhalation, and a second layer formed from a material selected to minimize or prevent the transmission of bacteria, viruses, or other contagions from a user's mouth to the smoking device. Each of the filtration layers can also be formed from one or more materials.

A mouthpiece for an article for use in an aerosol provision system. The mouthpiece can have a section having a longitudinal axis and a cross sectional area measured perpendicularly to the longitudinal axis, the section including a fibrous material having a total denier of between 300 and 500 grams/9000 m per mm2 of said cross sectional area. The section can additionally or alternatively have a fibrous material having a total denier of between 200 and 600 grams/9000 m per mm2 of said cross sectional area and at least one of more than 75 fibers per mm2 of said cross sectional area and a denier per filament of less than 9.0 grams/9000 m. A section of fibrous material can have a denier per filament of less than 5.0 grams/9000 m and a capsule embedded within the fibrous material, wherein the section has an outer circumference of less than 21 mm.

An article for use in a non-combustible aerosol provision system, the article comprising an aerosol generating material and a mouthpiece downstream of the aerosol generating material, wherein the mouthpiece comprises a body of material in the form of a cylinder having a longitudinal axis and a capsule embedded within the body of material such that the capsule is surrounded on all sides by the material forming the body, the capsule having a shell encapsulating a liquid aerosol modifying agent, and wherein the largest cross sectional area of the capsule measured perpendicularly to the longitudinal axis is less than 28% of the cross sectional area of the body of material measured perpendicularly to the longitudinal axis. There is also provided a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article.

A non-combustible aerosol provision system is described including an article (1) having an aerosol generating material (3) and a mouthpiece (2) downstream of the aerosol generating material, wherein the aerosol generating material provides an aerosol when heated and the mouthpiece comprises a capsule (11) and the part of the mouthpiece in which the capsule is located reaches a temperature of between 58 and 70 degrees Centigrade during use of the system to generate an aerosol. The burst strength of the capsule when located within the mouthpiece and prior to heating of the aerosol generating material can be between 1500 and 4000 grams force and the burst strength of the capsule within 30 seconds of use of the system to generate an aerosol can be between 1000 and 4000 grams force.

An article for use in a non-combustible aerosol provision system comprising an aerosol generating material comprising at least one aerosol forming material and a mouthpiece connected to the aerosol generating material, the mouthpiece comprising an upstream end adjacent to the aerosol generating material and a downstream end distal from the aerosol generating material, wherein the mouthpiece comprises a hollow tubular element formed from filamentary tow at the downstream end of the mouthpiece. There is also provided a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article, and a method of manufacturing articles for use in a non-combustible aerosol provision system.

Embodiments of the disclosure relate to an article for use in a non-combustible aerosol provision system, the article comprising an aerosol generating material and a mouthpiece connected to the aerosol generating material, wherein the mouthpiece comprises a cavity having an internal volume greater than 450 mm.sup.3. There is also provided a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article.

The present invention relates to polymer compositions comprising at least one basic additive, and processes comprising at least one process step to obtain the polymer composition or articles comprising the polymer composition. The polymer composition generally displays an enhanced biodegradability.

A filter assembly has an outer housing having an open first end and an open second end. An inner filter housing is within the outer housing adjacent the second end, and a gasket is provided at the first end of the outer housing. An internal chamber is provided between the first end of the outer housing and the inner filter housing, where during use, fluid from the within the internal chamber is drawn out the second end of the outer housing by way of the inner filter housing. A filter is provided within the inner filter housing. The gasket forms a gasketed opening smaller than the open first end of the outer housing. The gasket may extend axially adjacent a wall of the outer housing and abut the inner filter housing, such that the internal chamber is defined by the gasket and the inner filter housing.

Filters and cigarettes include an activated carbon sorbent capable of selectively removing nitric oxide from mainstream tobacco smoke. Methods for making cigarette filters and cigarettes using the activated carbon sorbent and methods for treating mainstream tobacco smoke produced by smoking a cigarette including the sorbent are also provided.
