GROHE filters FAQs
- The capacity of the 5-stage filters ranges from 600 l (S size) up to 2500 l (L size) (at 20° dKH).
- The capacity of the Magnesium + Zinc filter is up to 400 l at 17° dGH.
- The capacity of the Active Carbon filter is up to 3000 l (for soft water areas below 9° dKH).
- The capacity of the UltraSafe filter is up to 3000 l or max. 6 months.
- The life time of the Reverse Osmosis Membrane and Reverse Osmosis Mineralisation filter is 12 months.
The system is set on the basis of local carbonate hardness (°dKH). If the carbonate hardness is below 9° dKH, the Active Carbon filter should be used.
For carbonate hardness above 9° dKH, you can use our S-, M- & L-Size filters. Please note that the L-size filter is not suitable for GROHE Blue Home). To enrich the drinking water with magnesium and zinc, you choose the Magnesium + Zinc filter.
To remove even microplastic (> 1µm), 99,5 % of lead and 99,999% of bacteria, you aim for the UltraSafe filter. In addition, we recommend cleaning the inner waterways of your GROHE Blue cooler with the help of the GROHE cleaning cartridge every time you exchange the filter.
For challenging water conditions you can use Reverse Osmosis filters.
The filter has to be changed at least after 12 months*, or as soon as the filter capacity has been reached. The remaining capacity of the filter is shown in the cooler display, on the Watersystems app (relevant for GROHE Blue Home and Professional) or on the flow meter or exchange timer (relevant for GROHE Blue Pure).
An LED display in the faucet’s left handle makes it easy to tell when filter capacity is running low. If the residual capacity is <10 %, the LED on the handle flashes and, depending on the settings, you receive a push notification telling you the filter needs to be replaced soon.
When the time comes to replace the filter, the display on the tap will alert you with an orange, blinking light.
Using a GROHE Blue Pure watersystem, the flow meter or filter exchange timer give an acoustic signal when the filter capacity is exhausted.
(*UltraSafe filter has to be replaced after 6 months)
If the system is operated in the public/commercial sector (e.g. GROHE Blue Professional in a company’s kitchen or break room), a cleaning with the GROHE cleaning cartridge must take place twice a year.
If you use a GROHE Blue Home system at your own kitchen, we recommend to clean it once a year, or every time you replace the filter, to keep your GROHE Blue Watersystem working perfectly and delivering pure and delicious tasting water straight from the tap.
