A filter medium, in particular for air filtration, is provided with a substrate and at least one nanofiber layer applied onto the substrate. The nanofiber layer has cavities in or between the nanofibers. In a method for producing the nanofiber layer, a spinning solution for electrospinning from a polymer solution by a spinning electrode and a counter electrode is provided, wherein electrical voltage is applied to the spinning solution and air is passed through the spinning solution. The nanofibers produced by the spinning electrode are deposited onto the substrate that is moved past the counter electrode.
