Still, lightly sparkling or sparkling water? GROHE Blue Professional combines the modern look of a designer faucet with a high-performance filter, cooler and carbonator – and is as easy to use as an ordinary kitchen faucet. The right lever on the faucet is used to mix hot and cold tap water as usual. The left rotary knob with integrated coloured LED display regulates the carbonic acid content of the filtered and cooled water.
The carbonator integrated in the built-in box adds especially fine bubbles of carbonic acid to the filtered and cooled water to produce lightly sparkling or sparkling water according to taste.
