{"product_id":"cartridge-112-sqft","title":"Unicel C-7489 Cartridge, 112 Sq Ft","description":"\u003cp\u003eThe Unicel C-7489 is a 112 square foot replacement pool filter cartridge. Unicel lists it as the replacement for the Hayward cartridge CX875RE, and the element is listed under Hayward as the filter manufacturer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy area matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFilter area is dirt holding capacity. A 112 square foot element gives the pleats room to load before pressure rises, which is what determines how long you run between cleans. Fitting a smaller element in the same tank does not save money, it just means cleaning more often and running the pump against higher pressure in between.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the dimensions before ordering\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe manufacturer data for this cartridge carries two dimension readings. The attribute list gives a 7 in. outside diameter with a 25-1\/2 in. length, while the product description gives 25-3\/8 in. by 6-7\/8 in. by 3 in. Measure your existing element, or go by the Hayward number CX875RE, rather than ordering on the dimensions alone.\u003c\/p\u003e","brand":"Unicel Filter Cartridges","offers":[{"title":"Default Title","offer_id":48628833812692,"sku":"UNI-60-5289","price":91.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3fa7f4a2-833e-4d8a-b15d-ea95c2c28887.jpg?v=1788753713","url":"https:\/\/www.activepoolsupply.com\/products\/cartridge-112-sqft","provider":"Active Pool Supply","version":"1.0","type":"link"}
