Salt vs salt-free water softener: which one fits your home?
One removes minerals. One just keeps them from sticking.
Salt-based softeners remove hardness minerals. Salt-free conditioners change them so they don't stick as scale. Here's which fits your home.

Where salt is restricted
Some areas limit salt-based softeners because of salt in wastewater. In those places, salt-free is the practical choice. [Check local rules.]
Our take
How to choose in 10 seconds
This is the stuff our customers ask us most, after 20+ years and [thousands] of systems sold.
Ask yourself one question: do you want spot-free dishes and soft-feeling water? If yes, salt-based. If you mostly want to protect your water heater and pipes and never touch salt, salt-free.
Then check your water: iron or very high hardness rule out salt-free for most homes. We sell both, so we have no reason to push one.
