Abstract

An aerosol-generating article is provided, including a plurality of elements assembled in the form of a rod, the elements including an aerosol-forming substrate and an aerosol-cooling element located downstream from the aerosol-forming substrate. The aerosol-cooling element includes a plurality of longitudinally extending channels and has a porosity of between 50% and 90% in the longitudinal direction. The aerosol-cooling element may have a total surface area of between about 300 mm2 per mm length and about 1000 mm2 per mm length. An aerosol passing through the aerosol-cooling element is cooled, and in some embodiments, water is condensed within the aerosol-cooling element.
