best water softener salt buying guide

Generally, there are two types of water softener salt Sodium Chloride and Potassium Chloride. Sodium Chloride is used as table salt, but always keep in mind that you need a specific sodium salt for your water softener.

When it comes to Potassium Chloride, it can be the best choice with some of its environment-friendly features. It contains a low sodium diet, which best for your health. But Potassium Chloride can be more expensive then Sodium Chloride.

Before making any decision, understands the need for your water softener. If you have a salt-based water softener that works on the ion exchange process rather than a salt- free water softener than you must proceed further.

Understand your Demand:

Not all softener salts react similarly when it comes to health. People with kidney stones may have a health problem with sodium chloride, and then you can go for potassium chloride. That is a quite human-friendly substance but a little bit pricy too. Hence it is very important to have a proper understanding of your demand before making any decision.

Sodium Chloride has a bit saltier taste as compared to potassium if you have a problem with a salty taste then you should avoid buying sodium chloride.

Price & Performance:

When it comes to pricing, Sodium chloride is a quite pocket-friendly choice. The majority of the Softening salt manufacturers use Sodium Chloride due to its availability and affordability. Potassium Chloride is considered a bit expensive due to its rear availability. But it is advanced in performing as compare to Sodium Chloride.

Maintenance is mandatory:

Keep in mind that water softener salts do need a little maintenance even if you are buying an automatic one. Providing salt supply for the tank and cleaning the brine are mandatory maintenance for all water softeners. You have to schedule parameters for monthly salt fillings.

 How many bags of salt does it take to fill a water softener?

It takes roughly 10 pounds of salt to fill a 10,000 gallon (40,000L) capacity water softener. If the water softener holds 1,000 gallons (3,800L), the amount of salt needed is roughly 10 pounds (4.5kg). 

The amount of salt necessary to fill a water softener varies depending on the quality of the salt and the concentration level of the solution. Salt is sold in varying concentrations, ranging from 1 part per million to 1 part per million. The higher the concentration, the less salt is required.


A good quality softening salt is as important as a good quality water softener. On top of that, before making a decision, always keep a little research about your needs and demands. If your family has some health issues with sodium Chloride salt, then there is a better option for you in the form of Diamond Crystal salts, which is made up of Potassium a quite healthy substance.
