Approved Manufacturers
Two tiers of salt-free water softening. One shared philosophy.
Only Water® carries a short list of manufacturers we're willing to put our name behind. EcoSmarte® and NaturalSof® both condition water without salt and without synthetic polymer resin — they simply serve different budgets and performance tiers.
Tier 1 — Flagship

Ionization-based conditioning & oxidation
​
EcoSmarte® is the top-tier system in the Only Water® lineup — the manufacturer we recommend when a customer wants the strongest full-spectrum result across hardness, iron, and chlorine byproducts, without introducing salt, chemicals, or a synthetic media bed into the home's water. EcoSmarte® is rated for and supplies dedicated systems across well water, city/municipal water, pools & spas, and irrigation & agriculture — so the same underlying ionization technology scales from a single household tap to a commercial well or a full irrigation run. It is the system we install for customers who prioritize long-term performance and satisfaction over up-front cost.

Tier 2 — Value
NaturalSof®
Template-assisted, salt-free crystallization
​
NaturalSof® gives customers the same core promise — soft water with no salt, no synthetic polymer media, and no discharge to manage — at a more accessible price point. It's the system we recommend when budget is the deciding factor but the household still wants to avoid the drawbacks of a conventional salt-based softener.

BEST VALUE ALTERNATIVE
Where they agree: both EcoSmarte® and NaturalSof® solve the same underlying problem the same responsible way — conditioning hard water without dumping salt brine into a septic field or municipal sewer, and without relying on synthetic polymer resin beads that wear out and need periodic replacement. Only Water® helps customers choose between the two based on water chemistry, household size, and budget, not on a one-size-fits-all sales script.
Why It Matters
Soft water protects the things you can't easily replace.
Hard water and disinfection byproducts create slow, compounding costs. Properly conditioned water pays for itself across three parts of a property.
01 / PEOPLE
Skin, hair & daily comfort
Â
Mineral-heavy, chemically treated water can leave skin dry and hair dull, and affects how soap and shampoo rinse clean. Conditioned water is gentler on daily routines for every person in the household.
02 / LANDSCAPE
Irrigation & soil health
Â
Hard water leaves mineral deposits in irrigation lines, drip emitters, and soil over time, restricting flow and altering soil chemistry. Conditioned water keeps irrigation systems running efficiently and landscaping healthier. daily routines for every person in the household.
03 / APPLIANCES
Water heaters, fixtures & equipment
Â
Scale buildup shortens the life of water heaters, dishwashers, coffee equipment, and plumbing fixtures. Removing scale-forming minerals protects the mechanical lifespan of everything water touches.
Built To Last
American-made components, chosen for durability.
A treatment system is only as good as the plumbing it's built on. Only Water® pairs every installation with US-manufactured hardware — not the lowest-cost import fittings.
Pentair®
We spec Pentair® and Watts® components alongside solid brass fittings on every install, because the connections and valves around a system matter as much as the treatment media inside it. It's the difference between a system that's installed and a system that's engineered to hold up for decades.
