  • an aerosol is generated by igniting and combusting the aerosol-forming substrate.
  • an aerosol is generated by the transfer of heat from a heat source to a physically separate aerosol-forming substrate, which may be located in contact with, within, around, or downstream of the heat source.
  • a heat source in the form of a resistive heating blade may be inserted into the aerosol-forming substrate.

  • These high aerosol temperatures may be associated with a feeling of discomfort or mild pain for some consumers, as sensitive tissues such as lips, mouth, tongue and mucosae in general may come into direct contact with a downstream end of the aerosol-generating article during use. Therefore, it has also been known to include an aerosol-cooling element in an aerosol-generating article in which the aerosol-cooling element is adapted to favour cooling of the aerosol prior reaching the downstream end of the aerosol-generating article.
