1. A cartridge assembly for an aerosol-generating system, the cartridge assembly comprising:
a housing having a mouth end and an opposed device end configured to connect to an aerosol-generating device, at least one housing air outlet provided at the mouth end of the housing, and at least one housing air inlet provided upstream of the housing air outlet; and
a cartridge disposed in the housing, the cartridge including,
a fluid-permeable heating element disposed within the cartridge;
at least one cartridge air inlet;
at least one cartridge air outlet, the at least one cartridge air inlet and the at least one cartridge air outlet being aligned with one another in a different direction than a longitudinal direction of the cartridge; and
a cartridge airflow path extending from the at least one cartridge air inlet to the at least one cartridge air outlet, via the fluid-permeable heating element;
the housing having a housing airflow path extending from the at least one housing air inlet to the at least one housing air outlet, and including the cartridge airflow path between the at least one housing air inlet and the at least one housing air outlet, wherein, at least a portion of the cartridge is configured to be movable between
a first position, in which the cartridge blocks the housing airflow path and seals the fluid-permeable heating element within the cartridge such that the fluid-permeable heating element is sealed from the housing air inlet and the housing air outlet; and
a second position, in which the cartridge airflow path is open and connected to the housing airflow path such that the housing airflow path is unrestricted from the housing air inlet to the housing air outlet.
