NuvoH2O Water Softener & Filter Reviews

We can talk about NuvoH2O all day, but our customers say it best.

5 stars

"I love the saltless water softener system, my water is now clear and tasteless like water is supposed to be, water should taste like water, not full of crap that they add and say is good for us when it is poisoning or bodies. I tell people about this manor trio system and how easy it is to install and how fantastic it changed the taste of my water, I highly recommend this filtration system."

"Works great out here in Canyon Lake, Texas. Canyon lake water is very hard an lots of calcium build up....shows up in all the toilets and plumbing fixtures. I use the NuvoH2O Manor Trio and it clears up all the deposits and the water even tastes better. I've had the water softener systems you have to add salt to but this is much easier with no salt to add. Very happy with it."

5 stars

"I have had my Manor Trio system for about eight years, and I’m so glad I chose it. I live in an area with very hard water. With NuvoH2O I don’t get mineral build-up on my faucets and appliances. They are quick to ship replacement filters, and I’ve found the customer service to be excellent."

FAQs About NuvoH2O Whole Home Systems

How does NuvoH2O soften water without salt?

Instead of using salt to replace hard minerals, 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 you get the benefits of soft water without the slippery feel or added sodium.

Will NuvoH2O remove existing scale buildup?

Yes! Unlike traditional softeners that only prevent future buildup, NuvoH2O helps break down and remove existing scale, restoring water flow and protecting your appliances from further damage.

Does NuvoH2O remove beneficial minerals from water?

Nope! Our system keeps healthy minerals like calcium and magnesium in your water while preventing them from causing hard water issues. You get cleaner, better-tasting water without losing the good stuff.

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

Most NuvoH2O cartridges last about 6 months or 20,000 gallons, depending on your water usage. Replacing them is simple, and with our Autoship program, you’ll never have to worry about running out.

Is NuvoH2O safe for my family and the environment?

Absolutely! Our systems are salt-free, chemical-free, and waste-free, making them a healthier choice for your home and a more sustainable option for the planet.
