Most important from
170 reviews

Type of Salt
The type of pellet used in this salt works effectively.

Morton Water Softener Salt comes in two 25-pound bags, making it a convenient option for households looking to maintain their water softeners regularly. One of its key strengths is its high ranking as #10 in Water Softeners, showing its popularity and reliability in its category.

The product specifications lack detailed information about the type of salt, its purity, the form it comes in (such as crystals or pellets), and any additives it may contain. This makes it difficult to assess its effectiveness and compatibility with different water softener systems. Additionally, the manufacturer being listed as 'Generic' may raise some concerns about product consistency and quality control.

Despite these uncertainties, if you are looking for a well-received and popular water softener salt option, Morton seems to be a favorable choice, especially given its easy availability since August 2023.

The Snow Shield All Natural Solar Salt for water softeners is a premium-grade product designed to effectively treat hard water.

Buying Guide for the Best Water Softener Salts

Choosing the right water softener salt is crucial for maintaining the efficiency and longevity of your water softening system. Water softener 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 softener salt, it's important to consider factors such as the type of salt, purity, and form. Understanding these key specifications will help you make an informed decision that best suits your household 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, created through a mining and evaporation process. If you have a high-efficiency water softener or want to minimize maintenance, evaporated salt is a good choice. For standard systems, solar salt is a balanced option, while rock salt is more economical but may require more upkeep.
PurityPurity refers to the amount of actual salt versus other minerals and impurities in the product. Higher purity salts dissolve more completely and leave fewer residues in your water softener system. Purity is typically expressed as a percentage, with higher percentages indicating fewer impurities. For most households, a salt with a purity of 99% or higher is recommended to ensure efficient operation and reduce the need for frequent cleaning of the brine tank.
Form of SaltWater softener 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 are smaller and can dissolve more quickly, but they may cause bridging if not used properly. Blocks are less common and are typically used in specific types of water softeners. For most users, pellets are the best choice due to their ease of use and efficiency. If you have a specific type of water softener that requires crystals or blocks, follow the manufacturer's recommendations.
AdditivesSome water softener salts come with additives that help to clean the resin beads in your water softener system. These additives can help to remove iron, reduce scale buildup, and improve the overall efficiency of the system. If your water has a high iron content or you experience frequent scale buildup, choosing a salt with cleaning additives can be beneficial. However, if your water is relatively clean and free of iron, a standard salt without additives should suffice.
Compatibility with Water SoftenerNot all water softener salts are compatible with every water softening system. It's important to check your water softener's manual or consult with the manufacturer to ensure that the salt you choose is suitable for your specific model. Using the wrong type of salt can lead to inefficiencies and potential damage to your system. Always follow the manufacturer's guidelines to ensure optimal performance and longevity of your water softener.
