Abstract
(EN)
The present invention relates to an elongated smoking article (100) that comprises a cylindrical smoking body (10) with a combustible material and a hollow bore filter element (20) downstream to the cylindrical smoking body (10). The hollow bore filter element (20) comprises a first base area (21) facing the smoking body (10) and a second base area (22) opposite the first base area (21) and a hollow bore (25) extending from the first base area (21) to the second base area (22). The elongated smoking article (100) further comprises a filter membrane (50) that is arranged between the smoking body (10) and the hollow bore filter (20),thatcomprisesat least one filter aperture (55) aligned with the hollow bore (25),that is configured for filtering particles emitted by the heated smoking body (10), that is permeable for vapor emitted by the heated smoking body (10) and has an effective size between 0.5 µm and 1.5 mm. The invention further relates to a method for manufacturing a hollow bore filter for such an elongated smoking article (100). The present invention further refers to a smoking system (300) comprising the elongated smoking article (100) and a heating device (200) for heating the elongated smoking article (100) and also refers to a heating device (200) for such a smoking system (300).
