Each element carries 15 square feet of 8 ounce DE media across 42 pleats, and the filter takes four of them.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuy the set\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA Quad DE 60 runs on four cartridges working together. Replacing one and leaving three tired elements in place means the new cartridge takes the load and clogs early, so it is normally worth changing the full set at once.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDimensions and fit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe element measures 6-1\/4 inches in outside diameter and 20-3\/4 inches long. Both end caps are open with molded gaskets and a 3 inch inner diameter, matching Pentair part 178654. The same cartridge appears in cross reference lists as XLS-621, PC-1961, FC-1961 and 60151.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy DE media\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDE media filters finer than a plain pleated cartridge, which is the whole point of the Quad design. You get the water clarity of a DE filter without the grid and manifold assembly of a traditional DE tank, and the elements come out and go back in like cartridges.\u003c\/p\u003e","brand":"Unicel Filter Cartridges","offers":[{"title":"Default Title","offer_id":48646303645908,"sku":"UNI-051-6960","price":34.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_967c0820-809f-4526-a194-5e51c575fa38.jpg?v=1788987928","url":"https:\/\/www.activepoolsupply.com\/products\/cartridge-15-sqft","provider":"Active Pool Supply","version":"1.0","type":"link"}
