Reviews

Beyond a lab report, clean water is about the way your skin feels, the taste of your coffee, and the longevity of your appliances.

  • Simple system that efficiently prevents all scale. It's easy to replace the filter as needed. Much better than our previous salt-based system.

  • I absolutely love this system. I can already feel a difference in my water. I definitely highly recommend this product to anyone.

    Mark M.

  • When I’m with someone, and we talk about water, I tell them about this system and how easy it is to install and how it changed the taste of my water. I highly recommend this filtration system.

FAQs About NuvoH2O Systems

Contact us or call us at 877-688-6426

How do NuvoH2O Systems work without salt?

Our systems use CitraCharge™ technology, a citrus-based formula that binds to minerals like calcium and magnesium, preventing them from sticking to pipes, appliances, and fixtures. This means your appliances stay protected without added sodium or wasteful backflushing.

Will NuvoH2O Systems help remove existing scale buildup?

Yes! Our systems not only prevent new scale from forming but also break down existing buildup over time, helping your appliances run more efficiently and last longer.

Do these softeners remove beneficial minerals from the water?

No, our systems retain healthy minerals like calcium and magnesium, just in a form that won't cause scaling or buildup in your appliances.

How often do I need to replace the filter or cartridge?

It depends on usage, but typically, cartridges need to be replaced every 6 months to ensure optimal performance. Our Autoship program makes it easy to stay on schedule.

Are NuvoH2O Systems safe for my family and the environment?

Absolutely. Our salt-free, chemical-free technology is safe for drinking water, septic systems, and the planet. Get clean, appliance-friendly water with no wasted water and no added sodium.
