Nuvo water softener reviews (Best citric acid water softener)

The Nuvo water softener is one of the best salt-free water conditioners available on the market. It is also commonly known as a citric acid water softener.

The salt-free water softener does not remove hard water minerals but retains them in water conditioning so they do not form scale on appliances. 

The softener conditions hard water without the use of salt. Therefore, it helps save a lot of money on buying salt and energy used for regeneration.

How does a Nuvo water softener work?

The Nuvo water softener conditions water through a process called chelation.

Chelation prevents calcium ions from precipitating out and producing scale by binding and isolating them.

It has a cartridge that adds citric acid to water.

The citric charge released from the cartridge forms a ring structure that binds hard water ions, therefore, preventing scale and hard water deposits from forming.

To help understand better how citric acid works in this system.

Citric acid is a weak organic acid naturally found in fruits and vegetables.

It is a natural preservative and Chelant, which is mostly used to preserve foods and soft drinks.

When it comes to water, PH is the main thing that determines whether or not the scale will form.

Pure water has a PH level of seven, also known as neutral. If greater than 7 is alkaline or basic and less than 7 is acidic.

What does citric acid or citric charge do with hard water as it has a PH level above 7, which is alkaline? It lessens the likelihood that scale may emerge by bringing the PH level closer to 7, or a neutral level.

The system lowers the PH and stops scale from forming in your plumbing and water-using equipment.
