GROHE Blue® activated carbon filter (40 547 001):
Ideal for soft water areas, the activated carbon filter improves the taste by removing chlorine and metal substances but does not filter out carbonate hardness.
GROHE Blue® magnesium+ filter (40 691 001):
Enjoy additional health benefits by choosing the Magnesium+ filter model. It uses our five-step filtration process and it also adds magnesium to the water. Something of a tea and coffee connoisseur? Then this is the option for you, with the added magnesium delivering the best-tasting tea and coffee possible.
