Considering a Potassium Chloride Water Softener?


Potassium chloride is the alternative to the more traditional sodium (salt) softener solution.

So, what’s the difference?

Potassium Chloride and Sodium Chloride both use the same process and technique to soften water. They are designed to replace hard water minerals, such as Magnesium and Calcium, with Potassium and Sodium, respectively.

Ultimately, when it comes down to it, if you are price conscious, not too concerned with the environmental impact and not on a low-salt diet – using salt in your brine tank is the best choice for you.

Alterntaively, if price is not too much of an issue, you want to be environmentally friendy and have sodium-related health issues or would simply like to increase your Potassium intake – then Potassium Chloride is your solution.

It was in the early 1900’s that it was determined that salt could soften water and quickly became the standard approach via the ion-exchange technique. However, more recently (since the 80’s) Potassium has become a viable option. Predominantly for the fact that it is beneficial to a person’s health and considered an important nutrient for the environment – used commonly in agriculture. Conversely, it is argued that once the regeneration of the water softening cycle is complete, Sodium Chloride is discharged into drains and affects the performance of septic systems.

This is an interesting Environmental Impact Study performed by Water Quality Research Foundation (

Despite the salt impact resulting from the regeneration process, there are significant environmental benefits from the water softening process, regardless of weather Sodium Clhoride or Potassium Chloride is used.
