With an enormous power of 1600 Gauss, the magnetic fields ensure that Calcium and Magnesium do not crystallize into a hard deposit as normal. The Amfa4000 does not remove these minerals from the water, but suppresses the negative effects so that they no longer precipitate. The lime remains in the water but no longer adheres to your equipment and pipes. Read more about the influence of the number of Gauss in water softeners here.
