A filter arrangement for liquids including a filter element (6) that can be axially inserted into a filter housing (4) during assembly of the filter arrangement (1). After installation, this filter element (6) seals a back flow device at least for the liquid to be filtered with at least one seal (12) in front of a return flow channel (16). The device is configured in such a way that as the filter element (6) is axially withdrawn, a first seal (12 ; 20; 30; 40) can be initially released to enable return flow of unfiltered liquid, and as the filter element (6) continues to be axially withdrawn, a second seal (18; 22; 41) can be released to enable return flow of filtered liquid.
