The Pro H module softens the water and slows down the formation of limescale. It will help get rid of the annoying iridescent film that hardness salts form on the surface of the water.

The reduction in the rate of scale formation depends on the initial tap water, if it is a high salinity (above 5 meq / liter), the module will need to be regenerated too often. For very hard water, it is more profitable and more convenient to use reverse osmosis filters.

The Pro H module also removes iron Fe2 and manganese. It is easy to regenerate it yourself and you can do it repeatedly.
