This listing supplies the complete set of 4. If you need a single replacement element, look for part number CX1280XRE.\u003c\/p\u003e\n\n\u003cp\u003eEach element in this set slots into one of the four positions inside the SwimClear filter tank, working together to deliver high-capacity filtration for large residential pools. Replacing all four cartridges at the same time ensures even pressure distribution across the element bank, maximises filtration cycle length, and restores the filter to its rated 525 sq ft performance.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eHayward Part Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eCX1280XREPAK4\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e4-Pack (4 cartridges)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eFilter Area\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e525 sq ft (total)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eLength\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e32 13\/16\"\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e7\"\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eTop Inner Diameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e3\"\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eBottom Inner Diameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e3\"\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFits Into\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eEquipment Line\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eModel \/ Part Number\u003c\/strong\u003e\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eHayward\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eSwimClear Multi-Element Cartridge Filter 525 Sq.Ft.

This is not an exhaustive list. For certainty, verify the part number in your filter's manual or on the original cartridge before ordering.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePoolaroo Pro Tip\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, pull one of your existing elements and measure its length and outer diameter — confirm they match 32 13\/16\" × 7\" to make sure you have the 525 sq ft SwimClear configuration and not a different SwimClear variant. When it's time to clean, rinse each cartridge with a garden hose working top-to-bottom between the pleats — never use a pressure washer, which can damage the filtration media. For a deeper clean after a heavy bather load or algae event, soak the elements overnight in a dedicated cartridge filter cleaner to dissolve embedded oils and sunscreen before reinstalling. Because this filter runs four elements in parallel, always replace the full set at once: mixing old and new cartridges creates uneven resistance across the element bank, reducing both flow and filtration efficiency.\u003c\/p\u003e\n\n\u003c!-- wft:processed:: --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303480054035,"sku":"CX1280XREPAK4","price":497.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-cartridge-element-4-pack-for-swimclear-cartridge-filter-cx1280xrepak4-3.webp?v=1782772995","url":"https:\/\/poolaroo.com\/products\/hayward_cx1280xrepak4","provider":"Poolaroo","version":"1.0","type":"link"}
