Refreshing and delicious tasting water guaranteed! That's the beauty of GROHE Blue. Designed for areas where the water hardness is below 9° dKH.

The smart three-phase filter, which has a capacity up to 3000 litres, removes all unwanted materials and impurities. First coarse particles as dirt are filtered out. The activated carbon filtration refines the water taste by filtering bad tasting substances. And finally, the fine filtration captures even the smallest particles.

Replacing the filter is easy: simply unscrew the old filter, insert the GROHE cleaning cartridge, start the cleaning process and then replace it with the new filter. The result is pure potable water straight from the tap!
