Coffee is 98% water. So water of the highest quality is essential to creating the best possible coffee experience. The CLARIS Smart+ from JURA further revolutionises water filtration. The water filter technology ensures greater hygiene in the coffee machine, starting in the water tank itself. By choosing CLARIS Smart+ you enhance the protection, product safety and service life of your coffee machine, so you can enjoy the perfect cup of coffee – every time.
Key Features:
Filter capacity
CLARIS provides the ideal water quality for the perfect speciality coffees. The capacity of the filter cartridge depends on the water hardness. (at 1-5° dH: up to 65 l, at 6-10° dH: up to 60 l, at 11-15° dH: up to 55 l, at 16-20° dH: up to 50 l, at 21-25° dH: up to 45 l, at 26-30° dH: up to 40 l.
Consistently perfect coffee thanks to TÜV-certified hygiene
JURA coffee machines were certified as extremely hygienic by independent international testing organisation TÜV Rheinland in accordance with its own strict criteria. This proves that JURA maintenance products, precisely formulated to be effective with the electronically controlled programmes, guarantee TÜV-certified hygiene and cleanliness for every JURA coffee machine.
Limescale causes faults and impairs flavour
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 flavour 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.
CLARIS removes the need for descaling
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, aluminium and chlorine. Positioned directly in the water tank, the CLARIS filter freshly filters the water every time coffee is prepared. It completely absorbs harmful substances while retaining important fluorides, which help the flavours to really develop. With the optimum water quality, every cup of coffee becomes a full-bodied taste experience. CLARIS eliminates the need to descale the machine.

Why Buy?
Better tasting coffee that protects your Jura machine
Since coffee is mostly water, the quality of that water shapes every cup you brew. The Jura Claris Smart+ filter cartridge cleans the water right in the tank, so tap water taste problems never make it into your coffee.
This filter takes out chlorine, lead, copper and other substances that can leave a metallic or flat aftertaste, while keeping the fluorides that help coffee flavours come through properly. Because it filters fresh water every time you brew, each cup gets the same clean taste, whether it is your first coffee of the day or your fourth. It also stops limescale building up inside your machine, which means the heating element stays efficient and the machine is less likely to run into faults over time.
Fitting a jura water filter into your routine is simple: no extra steps, no separate maintenance schedule, and no need for regular descaling cycles that eat into your time. The cartridge lasts anywhere from 40 to 65 litres depending on how hard your local water is, and Jura's TÜV-certified hygiene standards mean your water tank stays clean between changes. It is an easy way to keep a Jura machine running the way it should.
