Abstract: A microplastic filter (also referred herein as fluid filter) for a washing machine has a filter housing, a first filter screen, a second filter screen, an inlet opening 16, and an outlet opening. The inlet and outlet openings communicate with each other through the first filter screen to define a direction of fluid flow. The first filter chamber has a retentate outlet, is particularly easy to handle if the second filter screen is arranged in a cavity of the filter housing, the inlet and outlet openings communicate with each other through the second filter screen, and the retentate outlet is arranged on a side of the second filter screen that faces the fluid flow.

Abstract: A filter material for a filter insert of a fuel filter for separating solid particles and water droplets from fuel. The filter material comprises a particle filter medium layer through which the fuel flows first during use and at least one coalescer medium layer which lies on the particle filter medium layer on the outflow side. At least one coalescer medium layer is gradient-free in the flow direction with respect to the geometrical structure and/or physical properties and/or chemical properties of the layers. The at least one coalescer medium layer has a thickness measured in the flow direction which is maximally as large as the thickness of the particle filter medium layer measured in the flow direction.
