Aerosol-generating system with a replaceable mouthpiece cover

A kit for an aerosol-generating system, comprising:

• a consumable cartridge for an aerosol-generating system, the cartridge comprising:
• a housing containing an aerosol-forming substrate;
• and
• an outlet formed in the housing, wherein aerosol generated from the aerosol-forming substrate is delivered through the outlet;
• and
• a plurality of compliant, readily compressed but resilient, mouthpiece covers, the compliant mouthpiece covers each comprising a tubular section and a filter portion connected to the tubular portion, the filter portion covering a bore of the tubular section,
• wherein the housing comprises a first wall surrounding the outlet and a second wall surrounding the first wall such that an open-ended annular recess is defined between the first and second walls, the annular recess being configured to retain one of the plurality of compliant mouthpiece covers to the housing, and
• wherein the cartridge further comprises:
• a resilient O-ring or helical spring received in a groove in the second wall, and
• a slidable collar,
• wherein the slidable collar is moveable between a first position in which the slidable collar does not compress the O-ring or helical spring and a second position in which the slidable collar compresses the O-ring or helical spring to grip a compliant mouthpiece cover when the compliant mouthpiece cover is received in the annular recess.

• an aerosol-generating device and a compliant, readily compressed but resilient, mouthpiece cover, the device comprising:
• a housing containing or configured to receive an aerosol-forming substrate;
• and
• an outlet formed in the housing,
• wherein aerosol generated from the aerosol-forming substrate is delivered through the outlet,
• wherein the housing comprises a first wall surrounding the outlet and a second wall surrounding the first wall such that an open-ended annular recess is defined between the first and second walls, the annular recess being configured to retain the compliant mouthpiece cover to the housing,
• wherein the compliant mouthpiece cover comprises a tubular section configured to fit in the annular recess and being configured to allow aerosol delivered through the outlet to pass through the mouthpiece cover and into the mouth of a user,
• wherein the mouthpiece cover comprises a filter portion connected to the tubular section, the filter portion covering a bore of the tubular section, and
• wherein the aerosol-generating device further comprises:
• a resilient O-ring or helical spring received in a groove in the second wall, and
