There is provided a non-combustible aerosol delivery system for filtering exhaled breath, the aerosol delivery system including a power source; a filter unit; an inhalate airflow path adapted to convey vapor generated by the aerosol delivery system to the user during an inhalation, and an exhalate airflow path adapted to convey breath from the user to the filter unit during an exhalation into the aerosol delivery system; wherein the filter unit contains at least one filter, and wherein the at least one filter comprises glass fiber, polypropylene, or combinations thereof.

An article for use in a non-combustible aerosol provision system includes a source of aerosol-generating material and/or a cavity for receiving a source of aerosol generating material, and a downstream section, the downstream section including a capsule at a location between about 28 mm and about 38 mm from a distal end of the source of aerosol-generating material and/or said cavity. There is also described a non-combustible aerosol provision system including the article.

Provided is an aerosol generating system including a holder configured to generate aerosol by heating a cigarette; and a cradle including an inner space into which the holder is inserted. The holder is configured to be tiltable with respect the cradle. The holder is inserted into the inner space of the cradle and then tilted to generate the aerosol.

There is provided a filter unit for a smoking article having a tube formed from filter material and the tube having a first portion and a second portion, wherein an inner diameter of the first portion is different from an inner diameter of the second portion. There is also provided a tube having a longitudinal axis, wherein a straight line following at least a portion of an internal or external surface of the tube intersects the longitudinal axis at an angle other than 90°. Also described is a body or tube of filter material having a longitudinal axis, a first end surface and a second end surface, said body or tube formed from a plurality of continuous fibres extending between said first and second end surfaces, wherein the density of said filter material is greater at said first end surface than at said second end surface. A body of filter material is also described having a longitudinal axis and a channel or recess formed in the body of filter material, the shape of said body of filter material having no lines of reflective symmetry, as well as a body formed from filter material, the body having an end surface and a recess formed in the end surface. A smoking article including the filter unit and a kit comprising a smoking article and a filter unit are also described.

An aerosol-generating article is provided, including: an aerosol-generating substrate; and a filter in axial alignment with the aerosol-generating substrate, the filter including at least one filter segment of filtration material formed of a plurality of fibres including a polyhydroxyalkanoate compound, in which the fibres provide a total external surface area within the filter segment of between 0.12 square metres per gram and 0.28 square metres per gram, and in which the at least one filter segment includes at least 20 percent by weight of the polyhydroxyalkanoate compound. A filter for an aerosol-generating article is also provided.

A tobacco smoke filter or filter element comprising: a longitudinally extending core which includes first and second longitudinally extending rods of tobacco smoke filtering material, wherein the first rod of tobacco smoke filtering material is distanced longitudinally from the second rod of tobacco smoke filtering material; a wrapper engaged around the first and second longitudinally extending rods such that the wrapper defines a cavity between the first and second rods of tobacco smoke filtering material; and at least one receptacle for an additive located in the cavity, wherein the maximum width or diameter of the receptacle for an additive is less than half the maximum diameter of the cavity and the void space remaining in the cavity is greater than 50% of the volume of the cavity, the receptacle being free to move within the cavity.

A method of manufacturing a conical filter body (1) for a conical smokable product filter, comprising the following steps: Providing a band-like or -shaped filed body material (3) Cutting out at least one blank (4) of predefined geometry from the band-like or -shaped filter body material (3), Connecting at least two sections (4.1, 4.2) of the at least one black (4) to form a conical filter body (1).

A method of manufacturing flavorant particles includes melting a food grade wax and a flavorant into a molten wax; solidifying the molten wax; and grinding the solidified molten wax into a plurality of flavorant particles. Another method of manufacturing flavorant particles includes melting a food grade wax and a flavorant into a molten wax, the molten wax having a melting temperature between about 50° C. to about 70° C.; and spray-chilling the molten wax into at least one solid flavorant particle, the solid flavorant particle having a diameter of between about 0.1 mm to about 2.0 mm.

A flavor inhaler includes a tubular holder that extends from a mouthpiece end toward a distal end, a flavor source that is provided in the holder, and a combustion type heat source that is provided at the distal end, and includes a protruding portion protruding from the distal end and a flavorant carried on the protruding portion.
