Abstract: A fluid filter, particularly suitable for high pressure and high volume use, comprises a cylindrical housing (201) having an attachment plate (209) at an inlet end (202) to which is attached a plurality of bundles (303) of fibers (211), with the fibers being left unsecured at their distal end adjacent an outlet (203) of the housing. Between the bundles is provided a balloon (212) which can be distended in order to crush the fibers around the periphery of the housing. In use, a fluid to be filtered is introduced into the inlet end, adjacent to where the fibers are secured. In order to flush the filter the pressure within the balloon is released, and a flushing fluid is passed through the housing in the same direction.
