Aerosol-generating article having compressible upstream element

Abstract

An aerosol-generating article for producing an inhalable aerosol upon heating is provided, the aerosol-generating article extending from a mouth end to a distal end and including: a rod of aerosol-generating substrate having a density of less than 300 mg per cubic centimetre; a downstream section located downstream of the rod of aerosol-generating substrate, the downstream section extending from a downstream end of the rod of aerosol-generating substrate to the mouth end of the aerosol-generating article; and a compressible upstream element located upstream of the rod of aerosol-generating substrate, the compressible upstream element being formed from a filter material and having a density of less than 140 mg per cubic centimetre.

Dependencies are inferred from the claim text.
