Abstract (en)
The present disclosure provides an aerosol generating system (100) comprising: aerosol generating means (132) configured to generate an aerosol for delivery to a user during inhalation; a mouthpiece for exhalation of air into the system; a filter configured to filter exhaled air entering the system through the mouthpiece during a user exhalation, wherein a bypass channel (221, 221') is configured to direct exhaled air to the filter whilst bypassing the aerosol generating means (132); one or more exhalation airflow sensors configured to detect an airflow property of exhaled air passing through the filter; and a controller (12) configured to determine a state of the filter based on the detected airflow property of exhaled air.
