Refridgerator Filter

For our Whirlpool refrigerator, model # ED2KHAXVQ01, the replacement filter seems to be PUR 4396841, which at the moment we can still buy at Lowes. It's the two-port, "Fast Fill" type. The box additionally says "Replacement cartridge #P2RFWG2 for Filter Model # P2WG2L, P1WG2L, P2WG2 and P1WG2". The filter can be ordered online at www.whirlpool.com/accessories, no doubt if you can navigate a nighmarish selection maze of course.
