If it's a Furdew 3L stainless steel fountain, these fit.\u003c\/p\u003e\n\u003cp\u003e• Triple-Layer Filtration — Activated carbon catches chlorine and odors. Ion exchange resin softens hard water. Fine mesh grabs hair and debris before they ever reach the pump.\u003c\/p\u003e\n\u003cp\u003e• One Pack Covers About 3 Months — Swap a cartridge every 2–3 weeks; every 2 weeks in multi-pet homes. Four cartridges keep one cat going roughly a full quarter.\u003c\/p\u003e\n\u003cp\u003e• Why Swapping on Schedule Matters — A spent filter stops catching anything and makes the pump work harder. Fresh carbon is the difference between water they actually drink and water they walk past.\u003c\/p\u003e\n\u003cp\u003e• Rinse Before First Use — Hold the cartridge under cold running water for about 30 seconds to wash off carbon dust. Drop it in, fill, and you're done.\u003c\/p\u003e\n\u003cp\u003eSubscribe and save 20% — set it once and never think about it again.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0804\/4445\/7182\/files\/7f430aa4-e89d-487f-8a1e-6e111377e6dd.png?v=1788923047\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Furdew","offers":[{"title":"Default Title","offer_id":49008814915806,"sku":null,"price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/4445\/7182\/files\/7f430aa4-e89d-487f-8a1e-6e111377e6dd_271d46ff-d3dc-4a90-9b27-42b071423a3a.png?v=1788939265","url":"https:\/\/furdew.com\/products\/furdew-cascade-smart-fountain-3l-stainless-steel-filter-cartridge-filter-cotton","provider":"Furdew","version":"1.0","type":"link"}
