AO Smith Whole House Salt-Free Descaler System – 6-Year, 600,000 Gal | City & Well Water

Overview

Meet the AO Smith Whole House Salt-Free Descaler System, a salt-free, chemical-free solution designed to reduce scale buildup across your home’s plumbing. It operates without salt bags, backwashing, or electricity, making it compatible with both city and well water systems. This descaler focuses on preventing mineral buildup, helping pipes and fixtures stay cleaner over time while delivering consistent water flow throughout your home.

What it does and what it does not do

Unlike a traditional softener, this system does not soften water or remove minerals that contribute to hardness. Instead, it alters how minerals interact with surfaces inside pipes, which can help reduce stubborn scale and keep fixtures looking and performing better.

• Chemical-free and electricity-free operation means quieter, low-maintenance performance
• Works with both well and city water systems for broad compatibility
• Designed for households of 4 or more people, supporting steady water use across daily routines
