Grohe Blue Filter

With the XXL 2500-liter Grohe Blue filter cartridge, you can turn ordinary tap water into delicious table water. During the five cleaning stages, the water quality and taste are continuously refined, removing all unwanted substances. Heavy metals and even the finest particulates are filtered out, and the lime content is reduced. What remains is purely delicious water for you to enjoy. Changing the cartridge is incredibly easy: simply unscrew the old filter cartridge, insert a new one - and you're done.
