How SoluCalc Works: The CO₂ Anti-Limescale Solution for Your Home
SoluCalc is a salt-free water softening system that protects plumbing and appliances from limescale using CO₂. Unlike traditional salt-based water softeners, limescale is not removed from the water but converted into a soluble form that no longer builds up, even at high temperatures. The SoluCalc system is explained in detail in the video below.

The Smart Way to Eliminate Limescale
Comparison
Why is SoluCalc better than salt-based water softeners?
Salt-free, the innovative alternative to salt-based water softeners
No more heavy salt bags to carry or buy regularly. No salty water, no polluting discharge, no sodium in your drinking water. Unlike salt-based water softeners: frequent handling of salt bags, brine discharge, and added sodium.
Essential minerals preserved
Water naturally retains calcium and magnesium, essential for health and taste. Unlike salt-based water softeners: sodium is added and minerals are removed.
Long-lasting and effective limescale protection
Limescale deposits no longer form on taps, boilers, and household appliances, extending their lifespan and improving energy efficiency. Unlike salt-based water softeners: effectiveness depends on refills, and limescale quickly returns if salt is forgotten.
Compact installation and minimal maintenance
A discreet system installed after the water meter. Approximately one CO₂ refill per year, carried out by a professional. Unlike salt-based water softeners: bulky tanks, salt storage, and more demanding maintenance.

REVIEWS
Discover why more than 40,000 customers are satisfied with SoluCalc
"Solucalc makes watersofteners based on CO2 instead of salt, and I have to say that this works very good. We used the water 5 days without CO2 because the bottle finished, and my god, we had a lot of hard water 'damage' immediately. So very happy with this easy solution that saves space. We had a very good contact with the sales guy and also during installation everything went super smooth."
"This system is a good alternative if you live in an apartment without the possibility of installing a salt water softener in the basement, as in my case. It works :)"
