It fits Anthony DE filters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the grid does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDE grids are the fabric elements the diatomaceous earth coats. That coat is what actually filters the water, and the grid is the frame and cloth that holds it in place. When the cloth tears or a seam separates, the DE has nowhere to sit and washes straight through into the pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSigns it is time\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDE returning to the pool after a charge, cloudy water that will not clear, or a filter that runs at unusually low pressure all point at a grid problem. Pull the set and look for splits and thin, worn fabric.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplacing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eGrids live in a matched set inside the filter. Fit the same size back in, and if the rest of the set is the same age and visibly worn, changing all of them at once avoids a second teardown.\u003c\/p\u003e","brand":"Unicel Filter Cartridges","offers":[{"title":"Default Title","offer_id":48627737493716,"sku":"UNI-60-5263","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_954e4ab6-042c-4540-8e12-b5e3a2526a6a.jpg?v=1788727546","url":"https:\/\/www.activepoolsupply.com\/products\/de-grid-17-5x-24-anthony-filters","provider":"Active Pool Supply","version":"1.0","type":"link"}
