Frequently Asked Questions
What does “salt-free” mean? Does it soften the water?
Salt-free systems, like the Whole House Salt-Free Combo and EcoPure, don’t actually soften water like traditional salt-based systems. They prevent scale buildup by changing the structure of the minerals, so they don’t stick to pipes and appliances. The Aquasana EQ-1000-AST also operates salt-free.
I have well water. Which system is right for me?
These systems are generally designed for city water. If you have well water, the Whole House Salt-Free Combo isn’t a good fit. You’ll need a system specifically designed for well water, often including sediment and iron filtration. Consider consulting a water specialist.
How often do I need to change the filters, and how much does it cost?
Filter replacement frequency varies. The EcoPure Salt-Free System needs filter changes every 6 months. The 20″ Big Blue 2 Stage will need filter replacements depending on sediment levels in your water. The Aquasana EQ-1000-AST lasts up to 1 million gallons. Costs also vary; check filter prices beforehand.
What’s the difference between the Whirlpool Hybrid and the other salt-free options?
The Whirlpool Hybrid is a salt-based water softener WITH a self-cleaning filter. The other options (Whole House Salt-Free Combo, EcoPure, Aquasana) use different methods to prevent scale without using salt at all. If you want true “softened” water (less mineral content), the Whirlpool is what you need.
I’m looking for something that removes chlorine and other chemicals. Which system does that best?
The Whole House Salt-Free Combo uses catalytic carbon filters for chemical removal, making it a strong contender. The 20″ Big Blue 2 Stage also reduces chlorine. The Aquasana EQ-1000-AST uses a carbon/KDF blend. Make sure to check independent reviews to see if they target contaminants that concern you.
