Abstract
A filter medium of a filter element for filtering a fluid has at least one nonwoven filter layer of synthetic individual fibers. The filter layer has an increasing level of compression in a flow direction of a fluid passing through the filter medium. The filter medium has a degree of separation for particles to be filtered that increases in the flow direction of the fluid through the filter medium. The filter medium is used in a filter element for filtering fluids such as fuel or air. In a method for producing the filter medium, the synthetic fibers are deposited on a support surface in such a way that an increasing level of compression is created in a direction toward the support surface by gravity and suction acting on the fibers.
