How Salt-free water softener works

A salt-free water softener 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 your appliances or surface.

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

The method does not work well if your water is higher than 10 – 12 grains per gallon.  Such water with a high hard 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 but below that you can use a salt-free water softener.
