10 Best Water Softener Salts 2025 in the United States

The Diamond Crystal 804017 Solar Naturals Water Softener Salt offers a solid option for maintaining your water softening system. This product features extra coarse solar salt, which is beneficial for its slow dissolving properties, ensuring a consistent release of salt into your system. Purity is a strong point here, as the solar salt is naturally evaporated from sea water, providing a high level of purity without unnecessary additives.

This makes it a good choice for those seeking a more natural option. The product is compatible with most water softeners, making it versatile for different systems. Its 50 lbs weight means it should last a while, depending on the hardness of your water and usage levels. However, the size might be cumbersome for some users to handle and store.

Customer reviews are generally positive, with a 4.4-star rating out of 5 from 654 reviews, indicating a high level of satisfaction. One potential drawback is that it doesn't include any special additives that some might prefer for additional water conditioning benefits. Additionally, being solar powered is a bit of a misnomer as it refers to the method of salt production rather than any functional power source. If you are looking for a reliable, natural water softener salt without extra additives, this product could be a good fit, but if you need something with added conditioners, you might need to look elsewhere.

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 Diamond Crystal 50 lb. Water Softener Salt from the Bright & Soft Series is a solid choice for maintaining your water softener.

Additionally, the product is compatible with most water softeners, making it a versatile option for various systems. Despite being a 50-pound bag that might be cumbersome for some users to handle and store, the Diamond Crystal Water Softener Salt remains a reliable, high-purity option. It should meet the needs of most households looking to maintain soft water.
