NuVo H2O Water Softener Review


The Nuvo H2O water softener is ideal for homes with one or two people and boosts the life of your plumbing system. It also prevents you from doing the tedious job of cleaning limescale to keep your home cleaner with less effort.





The NuVo water H2O softener can extend the life of your plumbing appliances and prevents limescale build-up for a cleaner home. It has been NSF and FDA approved and the system works by freeing water from salt through a chelation process to change the pH level of the water.

As a result, you’re able to use water without dealing with the hassle of a build-up of limescale. The idea of using the Nuvo H2O water softener is to help you spend less time cleaning limescale by getting rid of the root issue caused by the salt in your water.

Our NuVo H2O water softener review provides you with an outline of the main features, different models available, maintenance requirements, and downsides.

NuVo H2O Water Softener Overview

The technology used in NuVo H2O’s water softening system has been used for 30 years where they were initially focused on commercial uses to eliminate hard water. The company has now made its way into the homes of residents across Asia, Canada, the U.S., and Europe.

Key Features


CitraCharge Cell technology is used in the NuVo H2O water softener and has been patented and FDA approved. This system works by causing the pH levels in your water to become more balanced through chelating with citrine.

Magnesium and calcium ions are what cause limescale to be left on surfaces, such as tiles in your bathroom, and inside your plumbing system. The technology included with this water softener alters salt and other elements to reduce limescale problems without changing how the water tastes.

Types of NuVo H2O Systems


The Home model is best for places that are 1,000-2,000 square feet. It’s also recommended that you only use the home model in properties where there are no more than three residents.

It provides up to 15 GPM which allows you to use it to soften water without any noticeable changes to the flow.


The Manor NuVoH2O system is the largest salt-free water softener model available and can be used in homes that are more than 2,000 square feet. This model has an 18 GPM flow rate, making it the best water softener system for larger homes with up to four residents.


The NuVo H2O studio system has been specifically designed for smaller living areas, such as apartments and even RVs. There’s a water flow rate of 15 GPM, which makes it ideal for one person who’s living in an area that’s 1,000 square feet.

Due to this water flow rating, you’ll be able to soften water without any disruptions to your regular water pressure.

Salt-Free System

The NuVo H2O water softener works with a salt-free system. This means that minerals within your home water are retained rather than being removed.

Salt-free water softeners cause minerals to be altered to prevent limescale build up on surfaces.

As a result of the NuVo H20 salt-free water design, no electricity is required to install and use the device, and less water is wasted as nothing is being removed. These features make the NuVo water softener system easier to maintain compared to salt-based systems.


The overall design of the various NuVo H2O water softener models differs slightly.


The Home model includes installation ports that are 1” in size. As a result, you can use it with a supply line that’s ¾” in size. Furthermore, this unit weighs 9 lbs, which makes it easy to manage when it comes to installation.


If you have 1 ½” pipes, the manor system will work best as those are the kinds of pipes that it has been designed for. However, you’ll still be able to use this NuVo water softener with pipes of different sizes, but you’d need to use adapters, which could make the installation process take more time.


The NuVo H20 Studio system has been made to fit pipes that are ¾” without the need for adapters because it’s smaller compared to the other models.

We liked how it weighs just 6 lbs as it makes it easier to handle when you’re installing it.

Annual Maintenance

When you purchase a NuVo H2O system, you also receive one replacement cartridge. You’ll need to change the cartridge after a certain amount of water has been passed through the system to ensure that it continues working effectively.

  • Studio model – Replace the cartridge after 10,000 gallons
  • Home model – Replace the cartridge after 20,000 gallons
  • Manor model – Replace the cartridge after 50,000 gallons

The average household uses approximately 80-100 gallons of water every day.

Therefore, replacement cartridges for the Studio model wouldn’t need to be considered for approximately three years or more. The Home NuVoH2O system would require replacement cartridges after a year and twice a year for the Manor model.

Consideration Factors

  • The NuVo H20 replacement cartridges can be a lot of money, especially if you have more people in your household that use a lot of water regularly.
  • Make sure not to overtighten the NuVo H2O device during installation as it can cause the system to stop working effectively.
  • Some users are put off by the blue tint that can appear in their water when using this system. NuVo assures customers that this is a harmless temporary side effect caused by the NuVo system removing copper oxide. This doesn’t affect how the water tastes either.
  • It’s not recommended to install the NuVo water softening system in homes that include a well or wood fire boiler system.
+ Easy to install
+ Compatible with properties of different sizes
+ Improves longevity of plumbing appliances

Our Verdict: Recommended!

There are many water softeners available that work in different ways. This can make it more difficult to find the water system that’s best for your home. Now that you’ve had the chance to read through our NuVo H2O review, you’ll be able to make a better decision about whether it’s the right product for you.

We like how easy the installation process is and how this home water system can effectively reduce limescale to help you reduce the potential effects of hard water. However, in some water softener reviews of this product, verified users have mentioned how it gives their water a blue tint and can sometimes leave white spots.

Replacing the NuVoH2O cartridges can also become costly if you’re living in a home with four or more people. Therefore, we recommend that you consider these downsides carefully before deciding on a water filter.

All in all, this salt-free water softener system can be an easy way for you to reduce the amount of limescale build up in your home to prevent plumbing problems. It also means you can save time on cleaning limescale.
