The Hype vs. The Truth

Salt-free water conditioners come in various shapes, brands, and formulations. However, none of them remove hardness from the water. They only claim to reduce scale build-up in water heating devices. This becomes problematic when water heaters fail after the sale and the warranty has expired. Additionally, most tankless water heater and boiler manufacturers will void the warranty if their systems are connected to hard water or show evidence of hard water entering the heat exchanger.


Some companies use salt-free devices as a marketing tool, promising to install a softener if the customer is dissatisfied. However, they often do not refund the higher price paid for the salt-free device.


Conclusion: Cation exchange water softening remains the trusted, proven, and certified method for effectively removing hard water.
