A filter device (1) is provided for microfiltration and/or ultrafiltration, preferably for varnishes, such as cathodic dipping varnishes, for connection to a conduit, having a pressure housing (2) and at least one ceramic membrane filter element (3) located in the pressure housing (2). In order to make a filter device of the previously mentioned type available which is also suitable for the recycling of varnishes, particularly cathodic dipping varnishes, the ceramic membrane filter element (3) is electrically connected with at least one electrical conductor (5) and is grounded via the electrical conductor (5).
