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.

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 10 percent by weight of an aerosol former; and a filter segment formed of fibrous filtration material, the filter segment arranged in longitudinal alignment with the rod, in which the filter segment includes at least about 85 percent by weight based on a total weight of fibrous filtration material of a polyhydroxyalkanoate (PHA) polymer or copolymer, in which a resistance to draw (RTD) of the filter segment is between about 35 millimetres H.sub.2O and about 55 millimetres H.sub.2O, and in which a length of the filter segment is from about 4 millimetres to about 27 millimetres. A filter for an aerosol-generating article is also provided.

A device for use while burning smoking material and inhaling the resulting smoke is disclosed. The device can include a filter having a recess formed in a surface of a body along a curved face extending from the first end to the second end, the recess extending radially into the body. The smoking accessory can include a capsule containing a flavoring agent disposed within the recess. The device may be received by a first end a tubular member formed to receive a smoking material, that when burned passes smoke into the device.
