Abstract (en)
An aerosol-forming article (10) is disclosed having an improved filter at its axial downstream end, for instance a mouthpiece end. The improved filter comprises a filter segment (100) having a plurality of bores (102, 104, 106) extending there through. Advantageously, the aerosol-forming article having an improved filter at its axial downstream end (114) does not require a filter tow to prevent debris from entering a user's mouth. Moreover, the aerosol-forming article having an improved filter at its axial downstream end provides an improved airflow from an aerosol-forming substrate (20) to the mouthpiece end. For instance, by drawing the airflow through the bores rather than through a tow filter, the draw resistance can be reduced providing an improved delivery to the user. Additionally, by drawing the airflow through the bores rather than through a filter tow, an advantageous airflow can be created in the aerosol-forming article upstream of the filter segment, which can create a better mixing of the nicotine and vapour. Additionally, by drawing the airflow through the bores rather than through a tow filter, less vapour condenses in the filter, maximising the delivery of the vapour and nicotine.
