The Claris filter Pro Smart RFID uses special technology to communicate with your Jura WE espresso machine, ensuring that the water 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. This is very important, especially when you realize that about 98 percent of a cup of coffee consists of water. The water filter protects your Jura against limescale and extends the lifespan of the espresso machine. You'll automatically receive a message when the filter needs to be replaced.The Jura Claris Pro Smart RFID filter is suitable for Jura WE espresso machines.
