Title
(EN) AEROSOL-GENERATING ARTICLE FILTER HAVING NOVEL FILTRATION MATERIAL
(FR) FILTRE D'ARTICLE DE GÉNÉRATION D'AÉROSOL AYANT UN NOUVEAU MATÉRIAU DE FILTRATION
Abstract
(EN)
An aerosol-generating article (10)(100)(310) comprises: an aerosol-generating substrate (12)(114)(312); and a filter (18)(122)(314) in axial alignment with the aerosol-generating substrate, the filter (18)(122)(314) comprising at least one filter segment (126)(318) of filtration material comprising a plurality of fibres comprising a polyhydroxyalkanoate compound, wherein the fibres provide a total external surface area of between 0.12 square metres per gram and 0.28 square metres per gram. The at least one filter segment comprises at least 20 percent by weight of the polyhydroxyalkanoate compound.
