PURPOSE: A polymer filtering filter cartridge capable of replacing filtering material is provided which recycles boss, end cap and perforated pipe except the filtering material in constructing the polymer filtering filter cartridge. CONSTITUTION: In a polymer filtering filter cartridge comprising a filtering material of filter(12) for filtering impurities contained in reactant, a perforated pipe(13) for forming a framework of the polymer filtering filter cartridge, an end cap(11) installed at a front end of the perforated pipe, and a boss(14) installed at an end of the end cap, the polymer filtering filter cartridge capable of replacing filtering material is characterized in that a sealing member(15) is inserted into the depressed grooves by forming depressed grooves(11a,14a) circumferentially on the outer circumferential surface of the end cap and boss, and the filtering material and the sealing member are bonded to each other by pressing the filtering material of the filter positioned at an upper part of the depressed grooves, wherein the sealing member comprises metal fiber, Cu, Al or a mixture thereof, and wherein a pressure ring is formed on a bonded region of the filtering material and the sealing member.
