The FiltersFast FF-0121 pool and spa filter is the correct replacement for the Waterway 817-0125N. By using three essential components - spunbound polyester pleated filter media, thermally bonded polyurethane caps and punched PVC pipe - the FF-0121 provides lasting durability and continuous, crystal-clear water flow. While the FF-0121 meets and/or exceeds compatible OEM pool filters in performance and longevity, it also naturally prevents microbes, such as bacteria, mold, fungi, and mildew from growing or reproducing. Even when you backwash your pool's filter system, the FF-0121 can handle large amounts of dirt and waste water with ease.
