For use with any of the Grohe Blue or Grohe Red tap systems, this filter provides filtration of your water to remove impurities and improve taste. Featuring Grohe\'s own 5 step filter technology, regular tap water passes through a pre-filtration stage, which removes any particles, before passing through a carbon pre-filter. The water then undergoes an ion exchange which reduces lime content and removes heavy metals before passing through an active carbon filter, eliminating unpleasant taste or odour. Water finally passes through a fine filtration system to remove even the minutest of particles, for clear, pure water that tastes great.Quick and easy to fit, this replacement filter simply slots into place and is compatible with Grohe Blue or Grohe Red systems.Able to filter up to 600 litres of water, why not stock up on replacements today?
