FAQ about GROHE Home Blue

What is the difference between GROHE Blue Home and GROHE Blue Professional?

GROHE Blue Home is the solution for the home and non-commercial use. GROHE Blue Professional is the business solution but can also be used at home. The main difference is the capacity of the cooler. The GROHE Blue Home cooler delivers 3 liters of chilled sparkling water per hour, which makes it the ideal choice for private households, whereas the Professional cooler is designed to deliver 12 liters of chilled and sparkling water per hour.

Why do I need the cooler? Can the cooling be turned off?

The cooler is required for the carbonation of drinking water and is therefore necessary to produce sparkling water: The colder the water from the cooler, the more carbon dioxide can be bound. Moreover, the cooler should not be switched off for hygienic reasons to avoid contamination of the water.

What is the adjustable temperature range at the cooler?

The water temperature at the cooler can be set between 5 and 10 °C. It is set to the coldest level in the factory settings. The colder the water, the more carbon dioxide can be bound in it. This means that an increase in temperature has an impact on the water’s CO₂ content.

How can I adjust the level of carbonization?

The GROHE Blue tap provides filtered still water (top button) or filtered sparkling water (lower button). If you press both buttons in sequence, the tap provides medium sparkling water.

However, carbon dioxide binding in water is affected by various factors. The colder the water from the cooler, the more carbon dioxide can be bound. Another factor is the local carbonate hardness (°dKH) of the water.

Which kind of filter do I need?

If the carbonate hardness is below 9° dKH, the activated carbon filter should be used in any case, as this will not make the water even softer. For carbonate hardness greater 9° dKH, you can use the standard filter (S Size or M Size) or the Magnesium + Zinc filter.

To remove even microplastic (> 1µm) and 99,999% of bacteria, you choose the UltraSafe filter. We recommend to clean the GROHE Blue Home cooler with the GROHE cleaning cartridge every time you exchange the filter (at least once per year).
