The filter for gel shearing and particle filtration of molten polymer comprises a first layer of metal fibers of an average equivalent diameter between 8 and 65 [mu]m. The cross-section of the metal fibers has two neighboring straight sides with an included angle of less than 90 degrees and one or more irregularly shaped curved sides. The metal fibers have an average length of at least 6 mm. The metal fibers are bonded to each other by means of metal bonds; wherein the metal of the metal fibers of the first layer is the bonding agent forming the metal bonds. The filter comprises a second layer of metal fibers. The average equivalent diameter of the metal fibers of the second layer is smaller than the average equivalent diameter of the metal fibers of the first layer.
