Elevate your coffee's flavor with delicious, filtered water. The Saeco AquaClean filter uses innovative ion-exchange technology to micro-purify tap water and bring out the purest coffee flavor. You only need to descale every 5,000 cups – that's 20 times longer than your average water filter. Descaling ensures a smoothly running machine and yields the best tasting coffee and espresso. For use with Saeco super automatic espresso machines (with AquaClean sticker on the water tank), such as the Saeco PicoBaristo Espresso Maker. Micro-porous filter blocks any impurities for purer coffee flavor and aroma. Naturally removes calcium through ion-exchange technology. Patented flow path takes a long path in machine for deeper purification of water. Made in Switzerland.
