Salt free water softener

Installing a water softener in your water source is the only way to solve hard water problems.

In the past years, most water softeners used salt to remove excess minerals no longer needed, but there are considered to have a more negative aspect.

So, many brands have considered solving the problem by manufacturing a water softener that no longer uses the salt commonly known as salt free water softener.

The salt-free water softener is also known as the tankless water softener/saltless water softener or no salt water softener.

How Salt-free water softener works

It is also referred to as a water conditioner or descalers.

They don’t remove hard minerals they are retained in water, but they alter the chemical structure of salty water through a technology called Template Assisted Crystallization.

Any mineral present in water is changed and become harmless such that won’t affect or form scale on your appliances or surface.

Do salt free water softeners really work

A salt-free water softener does not soften water but conditions. That’s why it is also called salt free water conditioner.

It doesn’t remove hard water minerals but allow them remain in water.

The system alters the structure or changes minerals so that it does form scale on the appliances or house plumbings.

The method does not work well if your water is higher than 10 – 12 grains per gallon. 

Water with a high hardness level of chemicals requires a salt-based water softener.

Benefits of Salt-free water softener compared to the salt-based water softener

  • Prevent scaling without the need of using salt.
  • It requires no electricity to operate.
  • Salt-based water softener wastes a lot during backwash, but salt-free does not require salt there is no need for backflushing, therefore, saves a lot of water reducing the water bills.
  • Water softeners that use salt require salt to be added regularly. Addition of salt is the ongoing cost of operation.
  • A salt-based water softener is large so they need ample space compared to a salt-free water softener that is compact and small can fit anywhere. Also in addition to space water-based softener requires a drain nearby to discharge the backwash water.
  • Salt-free water softeners are best for those on a sodium-restricted diet or have cardiovascular issues.
  • Research has shown that minerals such that calcium and magnesium can have a health benefit, so salt-free water softener do no remove them but eliminate the problem of hard water leaving the healthy mineral for consumption.

What to consider when buying a salt-free water softener

Know your water level of hardness

A salt-free water softener is not for every hard water condition.

Test your water first, and if it has a hardness above 12 grains per gallon you need to buy salt-based water softener.

Testing for Water Hardness

Salt-free water softener types
