Zusammenfassung:The invention relates to a method for producing a filter device (1) for filtering a hydrophilic liquid, comprising a flat filter element (10) which is permeable to the liquid, wherein the filter element (10) has a delimited filter region (11) which is coated with a hydrophobic agent. The following steps are carried out:a) providing the flat filter element (10) which has in particular a nonwoven filter web (13) lying between a mesh support layer (14) and a spun-bonded fabric (15),b) producing a compressed annular boundary region (16) for the filter region (11),c) applying the agent onto the filter region (11) of the filter element (10), andd) obtaining the filter device (1).
