Grohe Blue Professional L spout set

Do you prefer your water still, sparkling, or medium? With Grohe Blue, you always have a choice. While you can tap regular tap water using the lever on the right side of the Grohe Blue, a turn of the left handle gives you chilled and filtered water, and you can even adjust the carbonation level in three stages - still, medium, sparkling. The color of the LED display on the handle immediately indicates which carbonation ratio you have chosen. Additionally, the LED display signals a color change and blinking when the filter capacity drops below 10%, indicating that the filter should be replaced. You can also set the water temperature to your personal preference between 6 and 10 °C.
