Salt free water softeners are actually not softeners they are water conditioners.
How do salt free water softeners work.

The simple and easy answer is no because in actuality what many companies call salt free water conditioners simply do not soften the water.
A more accurate description of units commonly marketed as salt free water softeners would be a salt free water conditioner or scale inhibitor.
In the salt free process minerals are retained in the water but their form is changed so they will not adhere to surfaces.
Water softeners mainly consist of systems using the ion exchange process reverse osmosis system deionization systems and distillation systems.
Water softening involves an ion exchange process which removes both magnesium mg2 and calcium ca2 from water.
In other words water conditioners are known as descalers or scale inhibitors.
Instead of salt free water softener you can call it a water conditioner.
