An aerosol generating device defines a flow path from an air inlet to an inhalable medium outlet. The device comprises a container for containing a liquid； a wick for drawing liquid from the container into the flow path, and a heating element, upstream of the wick, for heating inlet air from the air inlet to generate a flow of heated air in the flow path in use. The device is arranged such that, in use, the flow of heated air generated in use passes over the wick to volatilise the liquid to generate, in use, a flow of aerosol in the flow path. The device comprises a receiving portion in the flow path, downstream of the wick, for receiving an element for modifying a property of the flow of aerosol. A device comprising a shield element to shield the wick from a heating element is also disclosed.
