There is disclosed a mouth piece, filter element or cooling element 100 comprising: a longitudinally extending core of filtering material 102; one or more channels 104 extending longitudinally from an end of the core 102; wherein the or each channel 104 has a non-circular transverse cross section which varies in the longitudinal direction by rotating about a longitudinal axis I of the mouth piece, filter element or cooling element 100.

A smoking article (10) incorporates a tobacco rob (12) and a filter attached to the tobacco rod. The filter includes a concentric filter segment (20) having a central core portion (23) with sorbent material and an outer periphery layer (24) circumscribed about the central core portion. At least about 80 weight % of the sorbent in the smoking article is disposed in the central core portion. The central core portion has a lower RTD than the periphery layer. A ventilation zone (30) is disposed adjacent an upstream end of the concentric sorbent segment.

A filter for a smoking article has improved biodegradability and improved taste during smoking of the smoking article. The filter includes a segment having a filtration substrate including natural cellulose fibres, and a wrapper at least partly surrounding the segment. The filtration substrate contains a composition including an additive for reducing phenols.

A smoking article has a burn portion and a mouth portion. The burn portion includes a smoking rod filled with a smokeable filler material formed almost exclusively of cellulose material. The mouth portion includes either a filter portion with or without an interface or a tip with an interface. The mouth end may include an orthonasal property and the interface may store an additive.

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 cigarette filter includes a mouthpiece, a filter, a connection member, a cigarette seat, and a filter cotton. The mouthpiece has an air duct. The filter is combined with the mouthpiece and has a first and a second containing spaces. The first containing space is connected with the air duct. The connection member has a first and a second connection portions in opposite to the connection member. The first connection portion is in the second containing space. The second connection portion is disposed out of the second containing space. The cigarette seat is fastened to the second connection portion and receives the cigarette. The filter cotton is removably disposed between the air duct and the first containing space. The removable filter cotton is porous and absorbs an oil liquid which improves flavor of smoke.

A component for an article for use in an aerosol delivery system includes a body of fibrous material comprising first and second additive release components embedded within the body of fibrous material. The first and second additive release components each have a maximum diameter between about 1.5 mm and about 2.5 mm and the first and second additive release components are separated by a distance of less than about 2.5 mm. There is also provided an article including the component and a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article. A manufacturing method is also provided.
