    Abstract: A filter medium is provided with a first filter layer and a second filter layer that is arranged downstream of the first filter layer in a flow-through direction of the filter medium and has nanofibers. The first filter layer has a first filter layer section and a second filter layer section, wherein the second filter layer section is arranged downstream of the first filter layer section in the flow-through direction of the filter medium. The first filter layer section has a first packing density of fibers and the second filter layer section has a second packing density of fibers deviating from the first packing density of fibers.

    Abstract: A fuel filter has a separating device separating, from a medium flow comprising a first medium and a second medium, the first medium as a separated first medium contaminated with the second medium. The fuel filter has a cleaning device receiving a proportion of the second medium contained in the separated first medium. The cleaning device is arranged upstream of a discharge opening for discharging the first medium from the fuel filter. The cleaning device is provided with an absorbent/adsorbent cleaning material. The cleaning material contains or is made of an organoclay as an active component. The organoclay is a bulk material, wherein at least 50 wt. % of the organoclay has an average particle diameter of greater than 50 Φm and smaller than 1,000 Φm.

    Abstract: In a method for producing a filter medium, at least one substrate layer of a nonwoven comprising cellulose fibers and/or synthetic polymer fibers is provided and a fiber layer of polymer fibers is deposited on the at least one substrate layer. Prior to depositing the fiber layer, a solvent is applied to the at least one substrate layer, wherein a material of the substrate layer and/or a material of the fiber layer is soluble in the solvent. A filter medium produced by the method has material-fused connections at crossing points of the polymer fibers and/or cellulose fibers of the substrate layer with the polymer fibers of the fiber layer.
