{"product_id":"ultra-fine-filter-kit","title":"Maytronics Ultra Fine Filter Kit","description":"\u003cp\u003eMaytronics 9991466-R4 is the ultra fine filter kit for a range of Dolphin robotic pool cleaners. The cartridges are the accordion style, and the ultra fine grade is the one to reach for when the pool is holding fine debris rather than leaves.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMaytronics lists this kit for the S50, Active 10, Echo, Escape, E10, Saturn, Cayman, Prowler, 910 Encore and Nautilus CC. Check your model against that list before ordering, since Dolphin cartridge shapes differ between families.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy cartridges get replaced\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFilter media is a consumable. Rinsing after each run keeps a cartridge working for a long time, but pleats eventually stay grey no matter how they are washed, and the media tears at the folds. At that point the cleaner still drives its pattern but stops holding what it picks up, which owners often mistake for a suction or motor problem.\u003c\/p\u003e","brand":"Maytronics","offers":[{"title":"Default Title","offer_id":48626312020180,"sku":"MAY-201-3225","price":64.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_e7c5d20e-d30c-4604-89ab-686252fe206d.jpg?v=1788708053","url":"https:\/\/www.activepoolsupply.com\/products\/ultra-fine-filter-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
