It is the genuine Hayward part and it covers the full element set rather than a single grid.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the cluster is\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA DE filter works because the grids hold a coat of diatomaceous earth. The cluster is the assembled group of those grids, held in their correct spacing and ready to drop into the tank. Buying it as one assembly means every element in the filter is the same age and the same condition, which is how a DE filter is meant to run.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eGrids fail by tearing, by fabric thinning out, or by separating from the frame. The tells are DE dust returning to the pool after a recharge, pressure that rises again soon after a clean, and grids that will not come clean no matter how carefully they are rinsed. Once the fabric is compromised, patching one grid usually just moves the problem to the next one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis cluster is for the DE7220 size. Check the model number on the filter label before ordering, because the Pro-Grid line runs across several tank sizes and the clusters are not interchangeable between them.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48626222661844,"sku":"HAY-051-1487","price":1065.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/HAY-051-1487_1a.png?v=1788706499","url":"https:\/\/www.activepoolsupply.com\/products\/hayward-dex7200dc-de7220-pro-grid-pool-filter-element-cluster","provider":"Active Pool Supply","version":"1.0","type":"link"}
