Yes! I experienced that installing a whole house unit softened my water at my home in Nebraska.
You only need to install the whole house unit — one time — and that’s it. There’s nothing to add, nothing to remove, nothing to change, no ongoing costs, no salt to buy, no heavy bags to lug around, no huge jars of water to hoist onto a plastic dispenser, no parts will wear out, nothing will get ruined… And, there will be no added detrimental salts going into your body, affecting your long-term health.
