Many people make the mistake of believing that the salt based, and salt free softeners work in the same way. However, this is untrue here is information on how each system works and their differences.

Salt-Based Water Softeners

Water softening is by definition the process of removing Magnesium and Calcium out of the water through the process known as ion exchange with the used of a polymer-resin bed that lets off a sodium-particle for an exchange for the hardness minerals.


Salt-based water softeners make use of electronic-metered valve that is mounted on top of a fiberglass resin-tank which meter the water, followed by running the cleaning cycle as soon as the ion resin-bed has reached saturation point. In a cleaning cycle, an electronic-valve cycle will run a sequence of back-flashes that purge hardness particles which were captured through the system which then flushes these particles down the drain line. Sodium will also be replenished inside the resin-bed in the cleaning cycle, making the system ready start again.

Salt Free Water Softeners

In a salt-based process as explained above, which is known as true water-softening, the hardness minerals are removed out of the water. When in comes to the salt-free process the minerals remain within the water, yet their forms will change which means they will no longer adhere to any surfaces. The “salt free” water softeners technically are not classified as softeners, but rather “water conditioners.”

Through a salt-free water softener system, water will be processed through catalytic-media that makes use of a physical-process known as TAC (Template Assisted Crystallization). In this process hardness minerals will convert to hardness crystals which are unable to bind to any surfaces. This process conditions the water opposed to softening the water.

There are no electrical valves required for the salt-free systems as these systems operate as conditioners that don’t catch things, which eliminates the requirements of purging minerals.

Besides the fact that both these systems handle water hardness issues when it comes to scaling, here are the differences in these technologies.

Salt-Based Water Softeners

This system will offer you with a “slicker” feeling when it comes to water. You will notice that your soap creates more bubbles. This is because minerals have been removed out of water. Other stand out benefits of this system include clothes that are brighter in color.

Salt-Free Water Conditioners

These systems will create hardness crystals, leaving the minerals behind in your water. These crystals will not bind to surfaces, which means you will see a decrease in scale build-up. You might notice less soap-usage along with brighter laundry. The primary benefit you may gain from the salt-free systems has to do with minimal maintenance. This means no salt or chemicals, no wasted water and no electricity. The ideal way to determine which system is best suited for your home, would be to contact a professional company to request a water analysis. From the results, the technician will be able to advise you on what system is more suitable for your needs. To know more about us visit the website at
