Orange who?

Orange you glad there’s a water softener that doesn’t use salt?

Apologies for the bad knock knock joke, but we thought it was a fitting way to start a discussion about a citrus water softener. There are a lot of methods for treating hard water without the use of salt, but one of the more popular ones is employed by the nuvoH2O Salt Free Water Softening System. Instead of operating via ion exchange as conventional softeners do, this salt free system is designed to work through a process called chelation – and the fuel for this process is a proprietary citrus based filter media.

Like other salt free water conditioners, nuvoH2O promises all the benefits of a conventional water softener without the need for hefty bags of salt. Rather than trekking to your local superstore every month or so for water softener salt, you keep the nuvoH2O running by changing the filter cartridge every six to eight months. The cartridges are somewhat pricey, but the cost is comparable to what you would pay for a regular supply of salt for a conventional system. More importantly, ordering a cartridge online is infinitely more convenient.

Some other advantages of the NuvoH2O Salt Free Water Softening System:

  • It doesn’t remove calcium or magnesium from your water like conventional softeners do, or add in sodium – so your tap water is healthier to drink.
  • Because it doesn’t need a large tank to hold water softener salt, the system is compact.
  • We’ve written frequently about the environmental impact of salt based water softeners. This citrus based alternative is more eco-friendly.
  • The nuvoH2O system doesn’t use electricity, either. You simply hook it up to your water supply and let it do its thing.

On the downside, there are plenty of people who are unconvinced about the effectiveness of systems that use chelation. There’s a technical niggle here, as systems like these don’t actually soften water because they leave in the hard water minerals. The chelation process is intended to change their behavior so that they don’t cause scaling and other problems. Like a lot of salt free systems advertised as treating hard water, the nuvoH2O avoids calling itself a softener – instead using the term water softening system.

These criticisms haven’t been enough to stop the nuvoH2O from being one of the most popular saltless options on the market. It currently enjoys solid customer reviews and is available to order online at If you decide to order online, keep in mind that unless you know what you’re doing, you’ll also need to hire someone to install it. Installation is relatively simple, and should only take a plumber an hour or two.

As long as conventional softening remains such a hassle, it’s a safe bet that there will continue to be demand for no salt systems like the nuvoH2O. One of the main reasons people avoid buying a water softener is because they don’t want lug those heavy bags of salt around. But will citrus water softener systems become the standard in the future?
