Abstract

An aerosol-generating system, comprising: an aerosol generating substrate; an air inlet (); an air outlet (); an airflow passage () extending from the air inlet to the air outlet; an atomisation chamber () within the airflow passage; an aerosol-generating element within the atomisation chamber configured to atomize the aerosol-generating substrate to generate an aerosol; and an inlet filter () in the airflow passage between the air inlet and the atomisation chamber. Advantageously, the inlet filter is configured to allow for a flow of air into the airflow passage from the air inlet, through the inlet filter, but configured to prevent liquid, or liquid droplets greater than a predetermined size, within the airflow passage from passing through the inlet filter towards the air inlet.
