{"product_id":"the-clear-cup-jura-claris-blue-water-filters","title":"The Clear Cup | Replacement Water Filter Cartridges for Jura Claris Blue Machines","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eThe most expensive part of an espresso machine is the part nobody thinks about. Limescale forms inside the thermoblock and the brew group, narrows the water channels, and slowly changes the taste of every shot until the machine is descaled or replaced. The Clear Cup is the cheaper answer. Cartridges built for the Claris Blue fitment, dropped in every two months, and the water that reaches the coffee stays soft.\u003c\/p\u003e\n\u003cp\u003eInside each cartridge sit two working materials. Ion exchange resin pulls calcium and magnesium out of the water and holds them, and activated carbon removes chlorine, lead and copper while leaving the minerals that give coffee its body. The flow runs upward through the cartridge rather than sitting in it, which keeps water moving and makes the filter a poor home for bacteria. The result is water with hardness reduced by up to 80 percent, which is what protects the heating element and keeps the pressure steady at the group head.\u003c\/p\u003e\n\u003cp\u003eOne cartridge treats roughly 60 litres, which in normal household use means a change every two months. The compatible list covers the Jura GIGA 5, IMPRESSA Z9, Z7, J95, J90, J9.3, F8, F7, C9, C60, F50, A9, A1, ENA9 and ENA Mini machines, along with the ENA3, ENA4, ENA5, ENA9 and J9 models in the same family. Two option sizes are listed on the product selector, and the multi-pack keeps a year of cartridges on the shelf instead of ordering one at a time.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eScale takes years to build and one cartridge to prevent.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #eeeeee;\"\u003e\n\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style: none; padding: 0;\"\u003e\n\u003cli style=\"padding: 10px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003e✦\u003c\/strong\u003e Ion exchange resin reduces water hardness by up to 80 percent.\u003c\/li\u003e\n\u003cli style=\"padding: 10px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003e✦\u003c\/strong\u003e Activated carbon removes chlorine, lead and copper while retaining minerals.\u003c\/li\u003e\n\u003cli style=\"padding: 10px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003e✦\u003c\/strong\u003e Up-flow design keeps water moving and resists bacteria growth.\u003c\/li\u003e\n\u003cli style=\"padding: 10px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003e✦\u003c\/strong\u003e Each cartridge treats approximately 60 litres of water.\u003c\/li\u003e\n\u003cli style=\"padding: 10px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003e✦\u003c\/strong\u003e Recommended replacement interval of about two months.\u003c\/li\u003e\n\u003cli style=\"padding: 10px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003e✦\u003c\/strong\u003e Compatible with a wide range of Jura Claris Blue machine models.\u003c\/li\u003e\n\u003cli style=\"padding: 10px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003e✦\u003c\/strong\u003e Multi-pack quantities available so replacements are always on hand.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-specs\" style=\"margin-top: 30px;\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style: none; padding: 0;\"\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Water filter cartridge, Claris Blue fitment\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eModel Reference:\u003c\/strong\u003e 638\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eFiltration Media:\u003c\/strong\u003e Ion exchange resin and activated carbon\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Light blue\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eHardness Reduction:\u003c\/strong\u003e Up to 80 percent\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eCartridge Capacity:\u003c\/strong\u003e Approximately 60 litres\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eReplacement Interval:\u003c\/strong\u003e About every 2 months\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eFlow Direction:\u003c\/strong\u003e Up-flow system\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eCompatible Brands:\u003c\/strong\u003e Jura automatic espresso machines using the Claris Blue system\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eCompatible Models:\u003c\/strong\u003e GIGA 5, IMPRESSA Z9, Z7, J95, J90, J9.3, F8, F7, C9, C60, F50, A9, A1, ENA9, ENA Mini, ENA3, ENA4, ENA5, J9\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eAvailable Options:\u003c\/strong\u003e Two sizes listed on the product selector, 24.2 and 28.98\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003ePack Contents:\u003c\/strong\u003e Filter cartridges in the quantity selected\u003c\/li\u003e\n\u003cli style=\"padding: 9px 0; border-bottom: 1px solid #f0f0f0;\"\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Mainland China\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-applications\" style=\"margin-top: 30px;\"\u003e\n\u003ch3\u003eWhere It Belongs\u003c\/h3\u003e\n\u003cp\u003eHouseholds running a Jura automatic machine on municipal water, where hardness is the main long-term cost.
