Calmat is a unique alternative to water softeners that solves hard water problems without using chemicals or salt. It works maintenance-free and is very simple to install, no tools or plumbing are needed. It is an eco-friendly water treatment system that protects your piping system and appliances against existing scale deposits and rust. Calmat prolongs the lifespan of household appliances.


Calmat’s exclusive electric impulse technology is based on the principle of physical water treatment; changing the crystallization process of the liquid calcium. This way, the hard scale loses its adhesive power. Calmat works independently from the water velocity, unlike other systems that use magnetic fields.
