🎯What Are The Different Water Softener Salt Types?
🍵Evaporated Salt For Water Softeners
It is the purest form of sodium-based salts. It is an ideal choice for most softener systems, especially those requiring high performance, like single-tank systems or homes with more than 10 GPG water hardness.
Its efficiency and purity level ensure optimal softening and regeneration cycles, leading to longer resin life and less maintenance of the resin tank.
☀️Solar Salt For Water Softeners
An excellent choice for environmentally conscious homeowners with less than 10 GPG water hardness. Its natural production by sunlight makes it a sustainable option, and its high purity ensures proper softening.
- High purity
- Budget and eco-friendly
- It may dissolve slower than evaporated salt (so there are more chances of salt bridging or mushing)
- It’s not ideal for more than 10 GPG water hardness, high-demand situations, or both
🪨Rock Salt For Water Softeners
Extracted from underground salt sources, it is the perfect salt form for homes with high water usage thanks to its affordability and large granules that resist clumping.
However, this type of salt can require more frequent refilling due to its size.
- Large granules resist clumping
- Inexpensive option
- Ideal for high water usage
- Requires more frequent cleanings and refilling due to size
- It may dissolve slower

🅱️Block Salt For Water Softeners
Busy homeowners and those with low-maintenance systems often opt for block salt’s long-lasting convenience. This type of salt is slow-dissolving and requires less frequent refilling. Its size may not fit all softeners.
- Requires less frequent refilling
- Convenient for low-maintenance systems
- It can be messy to handle
- Larger sizes may not fit all softeners
🧪Potassium Chloride For Water Softeners
A sodium-free alternative for those on dietary restrictions or sensitive and dry skin to reduce their sodium intake. It’s just as effective in softening water but gentler on the body. However, its cost and slower dissolving rate may be factors to consider.
🪛Rust Defense Water Softener Salt
If your well water supply causes pesky iron rust stains, this specially formulated salt contains additives like citric acid to chelate iron and prevent rust on the water softener brine tank.
Water softener salt also comes in two forms: pellets and crystals. The pellet form is generally larger and dissolves slower, while the salt crystal form is smaller and dissolves faster. Choose pellet types of salt for high water usage for optimum water softening process.
🤔How Do I Know What Softener Salt to Use?
Consider these 4 factors in mind:

💡Water Softener Salt: FAQs
What is better, salt pellets or crystals?
Water softener salt pellets are best because they have larger granules that dissolve slowly, require less frequent refilling than crystals, and are ideal for high water usage or single-tank systems.
Which is better, potassium chloride or sodium chloride, for a water softener?
Sodium chloride (NaCl) is best for water softener as it dissolves correctly and ensures effective water softening.
Potassium chloride salt dissolves faster, is more expensive than NaCl, and its softening is less effective.
What’s the difference between blue and yellow water softener salt?
Crystal salts are kept in a blue bag (hence blue water softener salt), and pellet salt is kept in a yellow bag (hence yellow water softener salt).
Choose yellow water softener salt for best results.
How do you know when to add salt to a water softener?
You will know when to add salt to the water softener when:
1. The salt level is below 25% in the brine tank.
2. Water softener alarm goes on (or you get app alerts)
Is it OK to run a water softener without salt?
No, running a water softener without salt is not OK, as salt is essential in the ion exchange process that softens the water.
If you run a water softener without salt, the water softener resin beads will eventually become saturated with hard minerals and lose effectiveness.
This can result in hard water flowing into your plumbing and affecting the life of appliances, leading to the problems you were trying to avoid by using a water softener in the first place.
