Abstract
There is provided an aerosol-generating article (10) comprising an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouth piece (14) comprises at least one segment of porous filter material (20) and a blocking segment (27) that impedes air flow downstream of the at least one segment of porous filter material (20). The blocking segment (27) comprises a segment of support material (22) having an annular shape defining a channel (24) extending through at least part of the segment of support material (22), and at least one freshener delivery element (26) contained within the channel (24). The blocking segment (27) comprising the at least one freshener delivery element (26) is detachable from the at least one segment of porous filter material (20) to decrease the resistance to draw of the aerosol-generating article (10).
