Buying Guide for the Best Water Softening Salts

Choosing the right water-softening salt is essential for maintaining the efficiency of your water softener and ensuring the quality of your water. Water softening salts help to remove minerals like calcium and magnesium from your water, which can cause scale buildup in your pipes and appliances. When selecting a water-softening salt, consider the type of salt, its purity, and the form it comes in. Understanding these key specifications will help you make an informed decision that best suits your needs.
Type of SaltThe type of salt used in water softeners can vary, with the most common types being rock salt, solar salt, and evaporated salt. Rock salt is the least processed and contains more impurities, which can lead to more frequent maintenance. Solar salt is produced through the evaporation of seawater and is purer than rock salt. Evaporated salt is the purest form, made by evaporating water from a brine solution. The purer the salt, the less residue it leaves behind, which means less maintenance for your water softener. Choose a type based on how much maintenance you are willing to perform and the quality of water you desire.
PurityPurity refers to the amount of actual salt versus other minerals and impurities in the product. Higher purity salts, such as evaporated salt, contain fewer impurities, which means they dissolve more completely and leave less residue in your water softener. This can lead to more efficient operation and less frequent cleaning. If you prefer low-maintenance and efficient performance, opt for salts with higher purity levels.
Form of SaltWater-softening salts come in different forms, including pellets, crystals, and blocks. Pellets are the most common and are designed to minimize bridging and mushing in the brine tank. Crystals dissolve quickly and are suitable for households with low to moderate water usage. Blocks are less common and are typically used in commercial settings. The form you choose should depend on your water usage and the specific requirements of your water softener. For most residential users, pellets are a convenient and effective choice.
