JURA coffee machines were certified as extremely hygienic by independent international testing organization TÜV Rheinland in accordance with its own strict criteria. This proves that JURA maintenance products, precisely formulated to be effective with the electronically controlled programs, guarantee TÜV-certified hygiene and cleanliness for every JURA coffee machine.
When water is heated, limescale is deposited. Pipes narrowed by limescale not only slow down the heating process and therefore consume more energy, but may even cause the machine to break down completely. Limescale also has a negative effect on the coffee itself. Although a small amount of calcium carbonate is important to the flavor of coffee, too much gives the water an unpleasant aftertaste and prevents the coffee aromas from developing as they should, partly due to fluctuating water temperatures.
The right water is crucial to the taste of the coffee because coffee consists in fact of 98 % water. In addition to calcium, minerals and fluorides, the tap water in many areas contains traces of lead, copper, aluminum and chlorine. Positioned directly in the water tank, the CLEARYL filter freshly filters the water every time coffee is prepared. It completely absorbs harmful substances while retaining important fluorides, which help the flavors to really develop. With the optimum water quality, every cup of coffee becomes a full-bodied taste experience. CLEARYL eliminates the need to descale the machine.
