The Claris water filter Pro Smart RFID uses special technology to communicate with your Jura WE espresso machine, ensuring that the filter carries out its work very effectively. That's because the espresso machine recognizes when the filter has been installed and will automatically activate the right mode. The filter cartridge will ensure a consistent water quality, ensuring that your coffee tastes as good as possible. The filter also protects your espresso machine against limescale buildup, extending the espresso machine's lifespan. You'll be notified when the filter needs replacing, as it monitors its use.NOTE: this water filter is only suitable for the Jura WE machines.
