Choosing The Right Water Softener Salt

November 14, 2023

If you’re experiencing issues with hard water in your home, you’ve likely considered investing in a water softener. Water softeners are essential appliances that help remove the minerals responsible for water hardness, such as calcium and magnesium. However, to keep your water softener running efficiently, you’ll need to choose the right water softener salt. Keep reading as we explore the various options available and provide you with the information you need to make an informed decision on choosing the right water softener salt.

Understanding Water Softener Salt

Water softener salt is a crucial component of the ion exchange process that softens hard water. During this process, the salt replaces the calcium and magnesium ions in the water with sodium or potassium ions, leaving your water soft and free from the scaling that’s associated with hard water.

The three primary types of water softener salt are:

  • Rock Salt: Mined from underground salt deposits, rock salt is the least expensive option. It contains impurities and can leave behind sediment in your water softener tank. While it works, it may require more frequent cleaning and maintenance.
  • Solar Salt: This type of salt is obtained by evaporating seawater or brine from salt lakes. Solar salt comes in two forms: salt crystals and salt pellets. The crystals are usually more affordable but may contain impurities, while salt pellets are purer and dissolve more evenly.
  • Potassium Chloride: If you’re concerned about sodium intake, potassium chloride is a suitable alternative. It softens water in a similar way to sodium-based salts. However, it is more expensive than other options. Keep in mind that potassium chloride may not be suitable for individuals with specific health conditions.

Water Hardness

The level of water hardness in your area should influence your choice of salt. If you have extremely hard water, you may want to opt for a higher-purity salt like solar salt pellets to prevent sediment buildup in your water softener.


Consider your budget when choosing water softener salt. While rock salt is the most economical choice, it may require more maintenance in the long run. Solar salt pellets offer a good balance between affordability and purity.

Water Softener Type

Check your water softener’s user manual for any specific recommendations regarding the type of salt it can use. Some water softeners are designed to work best with particular types of salt.

Storage and Handling

Consider the ease of storing and handling the salt you choose. Some people find salt pellets or potassium chloride easier to handle and less messy than rock salt.
