Guide to Citric Acid Softeners

If you want to enjoy soft water at home but you don’t like the idea of adding salt to your water, you might have heard of one salt-free solution: the critic acid water softener.

In this guide, we’ve answered all the questions you might have if you don’t know much about citric acid water softeners.

A citric acid water softener, or a citric acid water conditioner, is a type of water treatment system that uses citric acid to reduce water hardness.

Citric acid water softeners work by chelating or sequestering hard water mineral ions, preventing them from forming scale deposits.

How Does a Citric Acid Water Softener Work?

Scale Prevention Method Salt-based softeners use ion exchange to physically remove hardness minerals by exchanging them with sodium ions, producing soft water in a literal sense.

Citric Acid Softeners Vs. Salt-Based Softeners

Citric acid water softeners use a “conditioning” process to prevent scale formation without actually removing hardness ions from the water. They use citric acid to treat water, making them a salt-free alternative to conventional softeners.

Regeneration is a process that only occurs in the traditional sense in a conventional softener. This is another difference to note between salt-free citric acid systems and salt-based systems.


The water treatment outcome is also slightly different when comparing a citric acid water softener to a conventional salt-based water softener system.
