A filter arrangement for filtering liquids has a central tube and a first filter element flowed through in radial direction outwardly and disposed on the central tube. A downstream second filter element is disposed on the central tube and flowed through in radial direction inwardly. The first filter element is moveable along the central tube from a basic position into an extended position. In the basic position a connection between the inlet line and a clean side of the first filter element is provided by the first filter element. In the extended position a bypass between an inlet line and the clean side of the first filter element is provided to bypass the first filter element. A spring element, applying a restoring force in a direction of extension of the central tube, is arranged on the first filter element at a side facing away from the second filter element.
