1. A capsule for an aerosol-generating device, comprising:
a housing having a gas-permeable end and an impermeable end, the housing including a container and an end cap, the end cap defining a plurality of openings, and the plurality of openings including an outlet opening surrounded by inlet openings;
a filter disposed within the housing so as to be adjacent to the impermeable end; and
an aerosol-forming substrate disposed within the housing so as to be between the filter and the gas-permeable end, the housing configured to facilitate a heating of the aerosol-forming substrate via one of conduction, convection, or both conduction and convection so as to generate an aerosol.
