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.
Dimensions & More Info
  • 2 1/2" x 3 3/4" x 5 3/4" high.
  • Model #CA6903/47ST.
  • Made in Switzerland.

Additional Information

  • Brew up to 5,000 cups before having to descale.
  • Each filter is good for 625 cups (approx. 3 months).
  • Prevents clogs in your espresso machine.
  • Easy Click & Go activation.
  • Automatically deactivates the machine's descaling alarm.
Use & Care


  • Remove the filter cartridge from packaging. Shake it for about 5 seconds.
  • Immerse the filter cartridge upside down in a jug with cold water and wait until no more air bubbles come out.
  • Replace filter cartridge every three months.
  • Keep filter cartridges in sealed package until it's time to replace current cartridge.
  • After 8 filter replacements, the espresso machine will reactivate the descaling process alarm, alerting that it's time to descale.
