1. A filtering device for the air to be supplied to a fuel cell or for filtering pesticides, comprising:
a carrier medium; activated carbon stratum as adsorbent arranged on the carrier medium; an adhesive immobilizing individual particles of the activated carbon stratum together; wherein the adhesive is a thermoplastic adhesive manufactured on the basis of polyolefins; wherein the adhesive bonds the activated carbon stratum onto a first face of the carrier medium; a second carrier medium having a first face; wherein the two carrier medium are spaced apart on opposing sides of the activated carbon stratum; wherein the activated carbon stratum is not bonded to or glued to the second carrier medium; wherein the activated carbon stratum is arranged on and abutting directly onto the first face of the two carrier medium; wherein an opposing second face of the two carrier medium does not have an activated carbon stratum secured thereto; wherein the opposing second face of at least one of the two carrier medium abuts directly onto a third carrier medium.
