The Jura Capresso Clearyl Blue water filters are designed specifically for these Jura-Capresso series of super automatic coffee centers. Without the use of chemical additives, the Clearyl Blue water filters reduce water hardness up to 75% and remove impurities, such as chlorine and calcium carbonate, from your water supply (minerals and fluorides important for health remain in the water.). The filters not only protect your Jura-Capresso machine, but also improve the taste of the water, and thus your espresso. Your Jura coffee center will alert you when it is time to replace the filter. The general rule of thumb is to replace the filter after 60 liters (about 14 gallons) of use. The filter cartridge is placed directly in the water tank and requires no accessories or additional space.After inserting the filter for the first time you must activate the filter program - see instruction manual for details.
