{"product_id":"11w-uv-quartz-sleeve","title":"11W UV System Quartz Sleeve Replacement","description":"\u003cp\u003eThe water that passes through a UV system usually carries small amounts of sediment and minerals. Over time these contaminants will build up on the surface of the quartz sleeve that protects the UV lamp.\u003c\/p\u003e\n\u003cp\u003eThis build-up will eventually cloud the sleeve and block the UV light from penetrating the water, allowing microorganisms to pass by without being killed.\u003c\/p\u003e\n\u003cp\u003eIn order to keep the quartz sleeve clean and operating properly the glass must be cleaned regularly (at least once a year when the lamp is changed) however you may need to clean them more often depending on water quality.\u003c\/p\u003e\n\u003cp\u003eIt is important that this is done gently with running water and a soft cloth as sediment on the surface of the sleeve can scratch the quartz.\u003c\/p\u003e\n\u003cp\u003eThese scratches can refract the UV light and reduce performance. It is recommended that the sleeve be replaced at least every 2-3 years.\u003c\/p\u003e","brand":"Finerfilters","offers":[{"title":"Default Title","offer_id":56193568702839,"sku":"UV-QUARTZ-11W","price":18.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0950\/9873\/2919\/files\/uv_sleeve-600x600.jpg?v=1763356828","url":"https:\/\/www.finerfilters.co.uk\/products\/11w-uv-quartz-sleeve","provider":"Finerfilters","version":"1.0","type":"link"}
