Enjoy fresh coffee from pure water with the Philips AquaClean Original Calc and Water Filter, which reduces the formation of limescale and keeps your machine clog-free. Activating AquaClean deactivates the descaling alarm and ensures optimal water purification through a patented water flow, thanks to its micro-porous filter that effectively blocks impurities. The filter naturally removes calcium using ion-exchange technology. The click-and-go system makes it easy to activate, ensuring your machine stays in top condition.
