Nuvo Salt-Free Water Softening SystemHow It Works
Water is a basic necessity. But what about the difference between hard water and soft water? Soft water will keep your plumbing, appliances, water heater, fixtures, dishes and shower doors scale free. It will leave your skin feeling soft and smooth. And it will help you save money because your water heater and appliances will work more efficiently and you will use fewer detergents and soaps.

Treating Hard Water

NuvoH2O treats hard water in two ways:

First, instead of removing calcium like traditional salt softeners, the NuvoH2O system chelates (binds) and sequesters (isolates) the calcium ions, preventing them from precipitating out and forming scale. Once bound to CitraCharge, the NuvoH2O chelant, the mineral cannot form scale.

Second, NuvoH2O also lowers the measured pH of the water to reduce or eliminate scale formation.

Effects of Chelation on Scale Formation

The NuvoH2O Salt-Free Water Softeners use a process called “Chelation” (pronounced key-LAY-shun). Chelation involves the binding, or stabilization, of mineral ions naturally found in hard water. The chelant in CitraCharge creates a ring structure to bind the ions to the CitraCharge instead of to other ions, which is what typically causes scale and hard-water deposits.

Our CitraCharge formula stops the mineral ions from causing hard water problems by making the typically troublesome minerals stay apart in the water, so instead of attaching to the metal in the pipes the water passes through. Since they’re bound, those minerals also freely wash away from your body, hair, dishes, pipes, fixtures, and appliances.

Effects of pH on Scale Formation

A primary ingredient in CitraCharge is an FDA approved citric acid. Citric acid is a weak organic acid that occurs in fruits and vegetables. It is a natural chelant and preservative, and is used in many foods and soft drinks. The table below has the pH measures of a number of everyday items.

pH is one of the key factors determining whether or not scale will form. pH is the measure of the activity or concentration of hydrogen ions in a solution. Pure water has a pH very close to 7 at room temperature. Solutions with a pH less than 7 are said to be acidic with the acidity increasing as the pH decreases. Solutions with a pH greater than 7 are basic or alkaline.

CitraCharge naturally decreases the pH of hard water—which is nearly always alkaline—to closer to the neutral range, substantially reducing its potential for scale formation. Since the pH scale is a logarithmic scale (like the Richter scale for earthquakes), even small changes make a big difference. For example, if water measured 7.9 on the pH Scale is decreased to 7.4, it experiences a fifty-fold (50x) decrease in hydrogen ions.

Proven Results – Independently Verified



With nearly 30 years in use, NuvoH2O’s technology has been proven in both commercial and residential applications. The technology was first used in commercial environments and was adapted for residential use more than 6 years ago. Since that time, NuvoH2O has been installed in tens of thousands of homes in the U.S., Canada, Europe and even parts of Asia.

Our technology’s effectiveness has also been independently verified by the world’s largest nonprofit research and development organization. At the behest of the EPA, NuvoH2O tasked Battelle with confirming and quantifying the benefits of the NuvoH2O system.

In order to put NuvoH2O through its paces, Battelle decided to test our products in the harshest real world environment possible. Using electric tankless water heaters (scale forms very quickly on electric heating elements) and municipal water with high grains of hardness, Battelle ran two experiments on the NuvoH2O systems. The first phase simulated over 2 years of water heater use to test NuvoH2O’s ability to prevent scale from building up. The second phase of testing used previously untreated water heaters with the NuvoH2O system to test NuvoH2O’s ability to remove existing scale.

Study Findings:

The results of the Battelle study were conclusive. “The NuvoH2O system prevents the formation of scale”. The visual assessment of the heating elements after teardown analysis clearly showed that the NuvoH2O system prevented scale. The study also found that the NuvoH2O system can remove scale and restore efficiency in untreated water heaters, something that other systems cannot do.

If NuvoH2O can prevent scale in the harshest of environments, we are sure our products can protect your home’s plumbing, appliances and fixtures from hard water!
