Abstract (en)
[origin: EP4218433A1] An aerosol generation device having a smokeless function and an aerosol-generating article used therewith are provided. The aerosol-generating article according to some embodiments of the present disclosure may include a tobacco rod which includes a first filter segment, a second filter segment, and a cavity segment. Here, the cavity segment may be filled with tobacco granules. Since content of moisture and/or content of an aerosol-forming agent in the tobacco granules is lower than that in other types of tobacco materials, generation of visible smoke can be significantly reduced. Also, accordingly, the smokeless function of the aerosol generation device can be easily implemented.
