The hygroscopic cartridge (1) particularly for filters for medical use, has a band-like element (2) which is wound to form a flat bobbin (7). The band-like element (2) has a first band (3), formed with corrugations (4) which extend in a transverse direction with respect to the longitudinal extension of the band-like element (2) and made of a heat-conducting plastically deformable material, and a second layer (5) impregnated with hygroscopic salts. The corrugations (4) define small channels (8) for allowing the passage of an aeriform flow in a transverse direction with respect to the plane of lay of the flat bobbin (7).

Hygroscopic cartridge particularly for filters for medical use, comprising a band-like element which is wound to form a flat bobbin, characterized in that said band-like element comprises a first layer, having corrugations which extend in a transverse direction with respect to the longitudinal extension of said band-like element and made of a heat-conducting plastically deformable material, and a second layer impregnated with hygroscopic salts, said corrugations defining channels for an aeriform flow in a transverse direction with respect to the plane of lay of the flat bobbin, wherein said corrugations are constituted by mutually parallel undulations, said undulations being inclined with respect to the longitudinal axis of said bobbin.
