Keep the caffeine flowing and your machine clean with the Philips Saeco AquaClean filter! Designed to drastically reduce your espresso machine maintenance, regular use of AquaClean filters lets you go up to 5,000 cups of coffee before a descale. A little bit of math: if you have four shots of espresso a day, you'll be able to go 3.5 <i>years</i> between descale cycles. That's a lot of espresso. Compatible with Philips espresso machines, as well as PicoBaristo, Incanto, and Xelsis models.
