It is supplied as a single cartridge and measures 26-3\/4 in. tall by 6-1\/4 in. wide.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOrder the right quantity\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is one element, not a complete set. A Quad D.E. filter runs several cartridges together, and they load up at the same rate, so replacing them as a group is what actually brings the pressure back down. Count what is in your filter before you order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA note on the rated area\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair source data is not consistent on this cartridge. The product name gives 80 sq ft, while the detail line gives 20 sq ft for the same cartridge in the same Quad D.E. 80 filter. The dimensions are consistent at 26-3\/4 in. by 6-1\/4 in., so measure the cartridge you are replacing and check the model plate on your filter before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCartridges survive many cleanings, but the fabric eventually holds oils and fine debris that will not rinse out. If a thorough wash no longer drops the filter pressure to its clean starting point, or the fabric is torn or thin, it is time.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626976850132,"sku":"PAC-051-8655","price":151.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_0931f6d1-0339-4a82-877a-0e929aa5086a.jpg?v=1788718667","url":"https:\/\/www.activepoolsupply.com\/products\/replacement-quad-de-80-sqft-cartridge","provider":"Active Pool Supply","version":"1.0","type":"link"}
