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 have a denier per filament (dpf) of between 5.0 dpf and 12.0 dpf, in which the filter segment includes at least 20 percent by weight of the polyhydroxyalkanoate compound, and in which a resistance to draw (RTD) of the filter segment is between 10 millimetres H.sub.2O and 25 millimetres H.sub.2O. A filter for an aerosol-generating article is also provided.

An aerosol-generating article is provided for producing an inhalable aerosol upon heating, the aerosol-generating article including: a rod of aerosol-generating substrate, the aerosol-generating substrate including at least 12 percent by weight of an aerosol former, and the rod having a length of from 5 millimetres to 50 millimetres; and a hollow tube segment with a support element and including fibrous filtration material, the hollow tube segment disposed immediately downstream of the rod and in longitudinal alignment with the rod, in which the fibrous filtration material includes fibres including a polyhydroxyalkanoate (PHA) polymer or copolymer, and in which the hollow tube segment includes at least about 25 percent by weight of the PHA polymer or copolymer. A system including an aerosol-generating device and the aerosol-generating article is also provided.

Smoking article include a smokable material and an activated carbon particle downstream of the smokable material. The activated carbon particle is produced from a whole seed. The activated carbon particle has a length, width and height. At least two of the length width and height are independently in a range from about 1 mm to about 7.5 mm. The particles can be spheroids, in which case the length, width and height would be the same or similar.

Additional filter device for cigarettes with fiber filter to reduce the passage of tar into the smoker’s mouth, thus reducing toxicity due to the combustion of the paper/tobacco mixture of the cigarette. Includes a laminar cylindrical body coaxially located between two sections of the cigarette fiber filter. The longitudinal middle area of the cylindrical body houses a transverse laminar disc having three holes, through which the smoke generated by the tobacco combustion and wrapping paper passes. The holes of the disc are equidistant from each other and are placed in a triangular configuration. The proximal and distal ends of the cylindrical body have annular flaps, which separate the disc from the fiber filter sections, and formed between these flaps and the disc, respective first and second air chambers where a high percentage of toxic substances contained in the smoke generated during the combustion of tobacco and wrapping paper is retained.

Some embodiments of the present disclosure provide a smoking article filter having a flavoring agent uniformly distributed in the smoking article filter, which is in a solid state at room temperature and includes at least one natural wax and a flavoring component soaked into the at least one natural wax.

The present disclosure relates to a smoking article including biodegradable cigarette paper.

An aerosol-generating article with improved cooling performance and flavor persistence and a method of producing the same are provided. The aerosol-generating article according to some embodiments of the present disclosure may include an aerosol-forming substrate part and a cooling part disposed downstream of the aerosol-forming substrate part and configured to cool an aerosol formed in the aerosol-forming substrate part, and a sheet-type material may be disposed on an inner wall of the cooling part. Here, the sheet-type material is a material including a flavoring and may serve as a cooling material as well as a flavor expressing material to improve cooling performance and flavor persistence of the aerosol-generating article.

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.
