Hard water affects over 85% of U.S. homes, causing scale buildup, appliance failure, dry skin, and higher utility costs. The question homeowners ask most is: “What’s the best whole house water treatment system for hard water?”

At AmeriFree Water, we design customized filtration and softening systems based on your unique home water profile. There is no one-size-fits-all solution — the best system is the one tailored to your hardness level, contaminants, plumbing, and household size.

Top Systems for Hard Water (2025)

2. Freedom Series FS1492 – Best Salt-Free Option

A maintenance-free whole-home filtration + scale-control system. Benefits:

• Eco-friendly

• No salt bags or brine discharge

3. Liberty Series LS1803 – Best All-In-One System

Combines softening + filtration to handle both hardness and chemical contaminants. Ideal for families who want premium water quality and no scale buildup in the areas that bother homeowners the most. This configuration requires custom installation of the whole house filter hooked up to the main water line "cold side" and the water softener hooked up to the hot water heater "hot side". This option can be hooked up to the entire home "cold side", if this is the configuration you would like we would recommend our Optimus X14 tankless RO system for drinking.
