Preferably, the proximal lip segment of the proximal lip filter segment 3 is a diverging cavity 1 in communication with an axial air flow channel 2. The function of the diverging cavity 1 is: cooling the smoke, emitting the smoke and enhancing the smoke mixing effect. The diverging cavity 1 is the closer to the proximal lip end of the proximal lip filter segment 3, the larger the inner diameter.
Preferably, the outer diameter enlarged section 5 or outer flange is located at the distal lip end of the proximal lip filter section 3.
A second aspect of the invention provides an aerosol-generating system comprising: the filter device, aerosol-generating article and aerosol-generating device of any of the first aspects;
