GROHE Blue Filter – great taste, pure water

The GROHE Blue S-size filter (capacity 600 l at 20° dKH) turns ordinary tap water into a premium table water. Through five purification phases, the water is continually refined into a soft potable water with a wonderful taste. Undesirable substances, fine particles and heavy metals are filtered out and the lime content is reduced, leaving pure, great-tasting water. The filter cartridge is easy to replace without any hassle: Simply unscrew the old cartridge, insert a new one, and you're ready to go. The filter is compatible with GROHE Blue Home, GROHE Blue Professional and GROHE Blue Pure systems. Phase 1: coarse particles like sand and dirt are filtered out / Phase 2: chlorine and organic compounds (insecticides, pesticides, etc.) removed by carbon filtration / Phase 3: lime and heavy metals extracted by the ion exchanger / Phase 4: activated carbon filtration ensures important minerals are not removed / Phase 5: fine filtration captures even the smallest particles

What does the filter do?

Why is this filtration important?

  + PERFECT TASTE Activated carbon filtration removes all unpleasant taste and odor.
  - LIMESCALE Limescale reduces the lifetime of hot water kitchen appliances.
  - HEAVY METALS Heavy metals (e.g. lead and copper from old pipings).
  - PARTICLES Rough particles (e.g. sand and dirt).
The filter protects drinking water systems and increases durability.
  - CHLORINE Chlorine is an unpleasant substance that has negative impact on water's natural pure taste.
