The FiltersFast FF-0121 pool and spa filter is the correct replacement for the Waterway 817-0125N. The FF-0121 produces long lasting durability and a crystal clear water flow which stems from three essential components - spunbound polyester pleated filter media, thermally bonded polyurethane caps and punched PVC pipe. In addition to meeting and/or exceeding compatible OEM pool filters in performance and longevity, it also deters microbe growth and reproduction -- making it a premier filter for your pool and spa!
