Saltless water softener: stop scale without hauling salt
No salt. No wastewater. Less maintenance.
A salt-free conditioner that keeps minerals from sticking as scale in your pipes and appliances, with no salt to buy and no wastewater. It doesn't remove minerals like a salt-based softener, so it's best for moderate hardness or areas that limit salt systems.
- No salt to buy
- Licensed install
- 30-day money-back guarantee

You're probably on this page because:
- You're done hauling salt bags
- Your area limits salt-based softeners
- You're mostly worried about scale in your water heater
Salt-free is great for the right home. Here's if that's you.
Hard water, by the numbers
- About 156 pounds of rock a year: what a family of 4 runs through its pipes at 10 grains of hardness. About 250 pounds in very hard water.
- Up to 48% less efficient: gas water heaters on hard water in testing.
- 1 in 3 homeowners replaced appliances or fixtures because of buildup.

An estimate, not a guarantee. Your numbers depend on your water, your home and your habits. Enter your ZIP code to use your local hardness; until then it assumes 10 grains.
Sources: Water heater efficiency: WQRF and Battelle (gas tank heaters lost up to 48% efficiency on hard water; the calculator uses a conservative middle value). Detergent: WQRF laundry and dishwasher studies (about 30% less at 10 gpg, nearly 70% less at 25 gpg). Fixtures: Battelle (low-flow shower heads clogged in about 18 months on hard water). Appliance figures are our own conservative estimate until customer data replaces them.

Our take
Why we tell some people not to buy salt-free
The question we get asked most about this, after [thousands] of installs:
Salt-free systems are popular, and for the right home they're great. But we turn people away from them more often than you'd think.
Here's what confuses people most: a salt-free system doesn't remove hardness. It changes the minerals so they don't stick as scale. That means if you test your water with a hardness strip afterward, it'll show the same hardness as before. Some homeowners think the system is broken when it's actually doing its job.
We'll steer you away from salt-free if: You want spot-free dishes and the soft-water feel. Salt-free won't give you that. Your water has iron or manganese. They coat the media and stop it working. Your water is extremely hard. Every salt-free media has a limit; check it against your test.
Salt-free is a great fit if you mainly want to protect your water heater and pipes from scale, your hardness is moderate, or your area restricts salt-based softeners.

Questions people ask
Does a salt-free water softener actually work?
For stopping scale, yes. It changes the minerals so they don't stick to your pipes and water heater. What it doesn't do is remove them, so your water won't test softer or feel softer.
Will I still get spots on my dishes?
You may see some. Spots come from the minerals still in the water, and a saltless system leaves them in. If spot-free dishes matter most to you, go salt-based.
Will my water feel soft?
No. That slick, soft-water feel only comes from removing the minerals, which takes a salt-based softener.
How often does a saltless system need maintenance?
There's no salt to add. The treatment media gets replaced every [3 to 6] years [confirm with partner].
Is a salt-free softener good for well water?
Usually not on its own. Iron and manganese, common in wells, coat the media and stop it working. Test your well first; our Well Water System handles iron the right way.
Does a saltless softener remove chlorine?
No. That takes carbon filtration, which our salt-free Ultimate system includes.
Is salt-free cheaper over time?
You skip buying salt, but you replace the media every few years. Long-term costs end up close; the real difference is what each one does to your water.
Can I use it with a tankless water heater?
It helps keep scale out of a tankless heater. Check your heater's manual for its water hardness requirements; some manufacturers ask for fully softened water.
