NuvoH2O: How It Works


The Simple, Smart Solution to Hard Water Problems

Water is a basic necessity. We need it for cooking, cleaning, drinking, and, very generally, staying alive. But do we need to have the best water? At NuvoH2O®, we believe in giving you access to the soft, clean water — in your own home by offering the hard water solutions you need.


Is Soft Water a Basic Necessity?

Let’s start with the difference between hard water and softened water: Softened 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. Hard water does the exact opposite.

Your Hard Water Solutions

The only solution you need for your hard water problems is to install a whole home salt free water softener from NuvoH2O. NuvoH2O delivers hard water solutions in two ways, both without salt:

First, instead of removing calcium like old-fashioned salt softeners, the NuvoH2O system chelates (binds) and sequesters (isolates) the calcium ions, rendering them incapable to bond to surfaces on/in your faucets, appliances, pipes, shower doors and heating elements.. Once bound to CitraCharge®, the NuvoH2O chelant, the mineral cannot form scale.

Second, NuvoH2O lowers the measured pH of the water, which works alongside the mineral chelation in reducing or eliminating scale formation.

Effects of Chelation on Scale Formation

The NuvoH2O Salt-Free Water Softeners offer hard water solutions by using a process called “chelation”. Chelation involves the binding or stabilization of mineral ions naturally found in hard water. The chelating agent in our CitraCharge® technology creates a ring structure that binds the mineral ions to the CitraCharge instead of other minerals, which is what typically causes scale and hard-water deposits.

Our CitraCharge formula stops the mineral ions from causing hard water problems by separating the typically troublesome minerals, so instead of attaching to the metal in the pipes, water can pass through easily. 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

The primary ingredient in our CitraCharge technology is citric acid. Citric acid is a weak organic acid that occurs naturally in many fruits and vegetables, commonly lemons, limes, and oranges. It is a natural chelant and preservative, and it 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.
