GROHE Blue® and GROHE Red® premium kitchen taps feature a revolutionary high-performance filter that removes the impurities that affect the taste and odour of ordinary tap water – heavy metals, chlorine and limescale – and so delivers the clean, refreshing taste that is expected from bottled mineral water. Two separate internal waterways – one for filtered water and the other for unfiltered water – and an innovative mousseur ensure that once the water has been filtered it never comes into contact with anything that may taint its taste.

1. Non-woven pre-filter
   Removes large particles.
2. Ion exchanger
   Reduces the lime content, filters out heavy metals from the water and reduces the hardness.
3. Activated carbon filter
   Removes substances which impair the smell and taste, such as chlorine and organic compounds.
4. Fine particle filter
   Captures all particles above a size of 10 μm.
