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.
