A domestic filter contains a case with at least one screw-like partition made with alternating or constant pitch, a grain filtering medium, inlet and outlet openings for water, a distributing grid before the outlet opening for water. The screw-like partition is made in the form of a twisted around longitudinal axis of the filter flat tape which edges by all over length adjoin to the lateral case surface. The bulk filtering medium is located screw-like between the partition and the internal case surface, and the filter is equipped with the second distributing grid located near the inlet opening for water. |
