The Hayward SwimClear C-3025 takes four cartridges, so this pack is the complete set for that filter in one order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDimensions and cross references\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEach cartridge measures 7 inches outside diameter by 19-5\/8 inches long, with open ends of 3 inch inside diameter top and bottom. The same cartridge is listed as Pleatco PA81, Filbur FC-1225 and Hayward OEM CX580XRE, so any of those numbers on the old element points here.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChange all four together\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCartridges should be replaced as a set. Water takes the path of least resistance, so a single new element in a bank of worn ones carries far more than its share, blinds off early, and leaves the filter running at a pressure that never really comes down. Rinse the new set on install and note the clean starting pressure, because that reading is what tells you when the next cleaning is due.\u003c\/p\u003e","brand":"Unicel Filter Cartridges","offers":[{"title":"Default Title","offer_id":48629308817620,"sku":"UNI-051-9510","price":258.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_b96d5d9f-2171-4156-9001-9fd25ab1d81e.jpg?v=1788762184","url":"https:\/\/www.activepoolsupply.com\/products\/filter-cartridge-4-pack-1","provider":"Active Pool Supply","version":"1.0","type":"link"}
