Each element is 15 square feet and measures 6-1\/4 in. in diameter by 20-3\/4 in. long.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow the Quad DE works\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRather than fabric grids, the Quad filter uses cartridges coated in DE. Four of these elements fill the tank, and together they give the filter its 60 square feet of area. The top and bottom end caps are open with molded gaskets and a 3 in. inside diameter, which is what seats and seals each cartridge in the tank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is inside\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe element is built with 8 ounce DE filter media in 42 straight, evenly spaced pleats, over a reinforced PVC center core drilled with evenly spaced holes so water distributes across the whole length. Polyurethane end caps hold it all square and take the clamping load.\u003c\/p\u003e\u003cp\u003eChange the set together. Four cartridges share the work, so leaving one worn element in the tank puts the pressure back up and shortens the run you just paid for.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626388926676,"sku":"PAC-051-8654","price":90.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/61fO4WVsIzL._AC_SL1000.jpg?v=1788709674","url":"https:\/\/www.activepoolsupply.com\/products\/replacement-quad-de-60-sqft-cartridge","provider":"Active Pool Supply","version":"1.0","type":"link"}
