About Philips water filters

Philips and Saeco espresso machines use the AquaClean Calc and Water filter, coded CA6903 with a regional suffix such as CA6903/10 or CA6903/22. Philips says to replace it when the machine indicates (a slow blink means buy a new one, a fast blink means change it) and at least every three months regardless. Replacing the filter eight times in sequence gives up to 5000 cups without descaling.
