Using the Device
Adjusting the Air Supply
Remove the pod and hold it so that the mouthpiece faces the floor.
By slightly turning the Airflow Control Ring on the centrally located chimney unit, you increase or reduce the airflow to suit
your personal preferences. The more air flows through the device (the further the air slit is open), the lower is the drawing
resistance.
