Zusammenfassung:	PURPOSE: To provide a sanitary filter capable of easy wash of filter media, easy maintenance, and executing washing without coming into direct contact with sludge and to provide a sanitary bath water circulation device enabling automatic wash of the filter media and being easy to maintain. CONSTITUTION: Many numbers of filter media 3 having flexibility deformable by a flow of water to be filtered and also having specific gravity of about 1, are packed. A first filter bed 2 for holding the filter media 3 at a filtering time and a second filter bed 4 for preventing an outflow of the filter media 3 at a backward washing time are installed. Also this bath water circulation device uses the filter as a screening device 1.
