GROHE Blue® FAQ

Yes, there is a GROHE Blue® Chilled and Sparkling version.

Yes, there is a GROHE Blue® Chilled and Sparkling version.

The LED display in the fitting’s left handle indicates the filter capacity:

• Continuous blue light - more than 10% filter capacity
• Flashing blue light - less than 10% filter capacity > order a filter cartridge
• Rapidly flashing orange light - less than 1% filter capacity > filter cartridge must be changed

GROHE Blue® systems also offer you a choice of filter size as well as three filter type options, meaning you can get perfect drinking water whether you live in a hard or soft water area.

There are 3 standard filter sizes available:

• S-Size (40404001)
• M-Size (40430001)
• L-Size (40412001)

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.

Yes, all filters have the same connections.

No, there are isolating valves built-in to the filter head. When the filter is removed it automatically shuts off the water.

The main benefit is that we have an Ion exchanger and that specially reduces carbonate hardness and binds heavy metal ions such as lead and copper. Most of the competitors filters are only an active carbon filter taking out chloride.

No, there are separate waterways inside the tap. The filtererd water outlet is slighly longer at the spout guaranteeing no cross contamination.

Power is required for the electronics that control the filter indicator on the GROHE Blue® filter handle. If power is shut off then the tap will still work and provide filtered water for the life of the filter.

Yes, the filter can be disposed of as normal plastics. Currently we do not refurbish the filter for re-use.

The electronic pack should be installed in an area under the sink with minimal obstruction. Obstruction of the sensor on the electronic pack can affect the accuracy of the filter life indicator.

GROHE Blue® filters use a five-step filtration process to remove even the smallest particles from tap water, while leaving behind all the important minerals that benefit your health:

• Pre-filtration: Filters out coarse particles of sand and dirt.
• Activated carbon pre-filter: Removes chlorine, certain organic compounds including insecticides and pesticides.
• High-performance ion exchanger: Removes limescale and metal substances
• Activated carbon filtration: Bypass water is filtered and purified while keeping essential minerals.
• Fine filtration: Captures even the finest remaining particles.

The electronics are adapted to the local flow rate conditions during installation. The electronics unit is adjusted as per the Installation instructions with the help of the GROHE Blue® carafe or a 1-litre measuring cup.

Yes, the filter can be adapted to different water hardnesses. There is an adjusting screw on the top of the filter head. Contact your local water supplier for the necessary data.

The filter has no expiration date, provided the packaging is not opened.

GROHE recommends not leaving the filter system out of service for extended periods of time. If the GROHE Blue® filter system is not used for a few days (2-3 days), the filter system must be rinsed with at least 4 liters of water. The filter system must be rinsed with at least 20 liters of water or replaced in its entirety after stagnation times of more than 4 weeks.

Yes. When the filter is depleted, it will no longer be able to purify the water but will allow normal tap water (drinking water) to pass through it.

No, the filter is specific to GROHE.

Flow rate at 3 bar flow pressure: fitting approx. 9 l/min, filter cartridge approx. 4 l/min.

GROHE Blue® purifies the already good quality tap water. Substances which are important for the body such as calcium and magnesium are retained, while the lime content is reduced and elements which affect taste such as heavy metals (iron, copper), chlorine and organic substances are filtered out.

The GROHE Blue® system does not change the mineral content of your tap water. Contact your local water supplier for details about the mineral content.

Enjoy additional health benefits by choosing the Magnesium+ filter (40 691 001). 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.

GROHE Blue® can be purchased from specialist bathroom or kitchen retailers.

Yes. The Article number is 40437000. You can puchase a set of 6 glasses in the GROHE webshop.

• Fresh taste – Water simply tastes better when it is fresh – ideally direct from the spring. This taste can now be experienced at home with GROHE Blue®. A blind test proved that GROHE Blue® water tastes at least as good as the leading brands of mineral water and is even better in terms of freshness of taste.
• Fresh and convenient – GROHE Blue® produces a high-quality water which bubbles out of your own home spring in an instant. For you, this means no more carrying home bottles of water.
• Protection of the environment – The production and transport of bottled mineral water is harmful to the environment. GROHE Blue® makes both unnecessary.

Yes. The GROHE Blue® handle provides the following means of dispensing water:

• Setting 1 - cooled still water

GROHE recommends that you store the 2kg bottle only in rooms with more than 13 m².

You can do it yourself or contact GROHE to get a recommendation for an installer: 0871 200 3414

It is installed underneath the tap (e.g. invisibly under the sink). Either directly at the cooler or in another easily accessible location near the cooler.

Yes, the filter can be adapted to different water hardnesses. There is an adjusting screw on the top of the filter head. Contact your local water supplier for the necessary data.

The filter cartridge reduces the water hardness of the drinking water as a function of the adjustable hardness of the water. Furthermore the cartridge binds heavy-metal ions such as lead, copper and cadmium. It also reduces cloudiness as well as organic and taste-impairing constituents and chlorine residues. Contact your drinking water supplier for water analyses.

Service life approx. 600 liters (10° dH) or max. 12 months. The litre amount depends on the carbonate hardness of the water, not the overall hardness.

Yes. When the filter is depleted, it will no longer be able to purify the water but will allow normal tap water (drinking water) to pass through it.

Yes. We provide an availability guarantee for the filter.

The filter can be disposed in normal domestic waste. The activated carbon it contains improves its combustibility in incinerating plants.

No, the filter can be easily replaced in four short steps:

• Step 1: Unscrew the filter from the filter head
• Step 2: Press the left button twice to reset the digital display
• Step 3: Screw the new filter into the filter head
• Step 4: When the display shows 99% filter capacity GROHE Blue® is ready to go again

The tap can be operated with pressurised storage heaters as well as thermally and hydraulically controlled instantaneous heaters. It cannot be operated with unpressurised storage heaters (displacement water heaters).

Flow rate at 3 bar flow pressure: fitting approx. 9 l/min, filter cartridge approx. 4 l/min.

Only normal water can be drawn in the event of a power failure. GROHE Blue® water cannot be drawn.

It is a special two-piece flow straightener which keeps the water channels of the tap water and the filtered GROHE Blue® water separate.

Yes, 5 years from date of purchase.

The water can be cooled down as far as 4°C depending on the ambient temperature.

Yes, it is ideally suited for kettles, etc. since the reduced lime content of GROHE Blue® water protects the appliances.

GROHE Blue® is also well suited for this. Despite the reduced lime content, there is still enough lime in GROHE Blue® water to make drinking tea and coffee enjoyable. With this method of beverage preparation, lime acts as a flavour carrier and should never be filtered out of the water completely.

No, GROHE Blue® only reduces the carbonate hardness of the water, all of the essential minerals remain in the drinking water. Only substances which are of no importance for humans are removed from the water, which is why we talk about purification.

Yes. A representative group was given water including GROHE Blue® and leading brands of mineral water for a blind tasting. The result was that GROHE Blue® water tastes as good as the mineral waters and was even better in terms of freshness of taste.

Please buy a piece of foam/rubber mat to reduce the sound which is being produced by the cooler, make also sure that the cooler stays straight!

That depends on the quality of the drinking water. In principle, however, it is recommended to only use special shop-bought water for baby food in the baby’s first year.
