Abstract:
An aerosol generating article (10) comprises: an aerosol generating substrate (12); a filter (14) in axial alignment with the aerosol generating substrate, the filter (14) comprising at least one water dispersible filter component (16), wherein the filter component is water dispersible under the test conditions of EN 14987:2006; and a tipping wrapper (20) wrapped around the filter (14) and at least a portion of the aerosol generating substrate (12). The tipping wrapper (20) comprises: a first weakening line (22) extending around at least a portion of the tipping wrapper (20); a removable tipping wrapper portion (26) extending downstream from the at least one weakening line (22) and at least partially overlying the water dispersible filter component (16); and an upstream tipping wrapper portion (24) extending upstream from the first weakening line (22), wherein the upstream tipping wrapper portion (24) is attached to a downstream portion of the aerosol generating substrate (12) and an upstream portion of the filter (14).
