Abstract
A capsule for an aerosol-generating device may include a housing, a filter, and an aerosol-forming substrate. The housing may have a gas-permeable end and an impermeable end. The filter may be disposed within the housing so as to be adjacent to the impermeable end. The aerosol-forming substrate may be disposed within the housing so as to be between the filter and the gas-permeable end. The housing may be 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.
