Salt-Free Water Conditioner (best for the whole house)

A salt-free water conditioner is the best water softener alternative or ideal for people with a sodium-restricted diet.

Hard water has so many adverse effects on our homes and a negative impact on our bodies.

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 salt, commonly known as a saltless water softener.

Salt-free water conditioners are also called “salt-free softeners.”

The salt-free water conditioner is also known as the salt-free softener, TAC water conditioner, citric acid water softener, water descalers/tankless water softener/saltless water softener, or no salt water softener.

How does a salt-free water conditioner work?

Salt-free water conditioners don’t remove hard minerals, but they alter the chemical structure of salty water through a technology called Template Assisted Crystallization.

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

Do salt-free water conditioners really work

A salt-free water softener does not soften water but conditions.

It doesn’t remove hard water minerals but allows them to remain in the 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 such as a single tank water softener, Cabinet style water softener, and Twin tank water softener.

Benefits of Salt-free water conditioner 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, it saves a lot of water reducing the water bills.
  • The salt-based water softener requires a drain nearby to discharge the backwash water.
  • Water softeners that use salt require salt to be added regularly. The addition of salt is the ongoing cost of operation.
  • A salt-based water softener is large and requires a lot of space, whereas a salt-free water conditioner is light and compact and can fit almost any place.
  • Salt-free water conditioners are best for those on a sodium-restricted diet or who have cardiovascular issues.
  • Research has shown that minerals such that calcium and magnesium can have a health benefit, so salt-free water conditioner does not remove them but eliminate the problem of hard water leaving the healthy mineral for consumption.

What to consider when buying a salt-free water conditioner

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 a salt-based water softener.
