A Deep Dive into Water Softener Salts – A Comprehensive Review

In a world flooded with myriad types of water softener salts, making an informed choice can be overwhelming. This article aims to simplify your decision, offering a thorough examination of the most popular and effective salts available, and ensuring your water softener operates at its peak efficiency.

The ABCs of Water Softener Salt

Before delving into the intricacies of water softeners, it’s essential to decode the ‘why’ – the core reason necessitating this investment. The culprit is hard water, an unassuming yet potent element with an affinity for calcium and magnesium, causing the dreaded limescale.

The Genesis of Hard Water

Water softener salt is integral to the brine tank of a water softener, playing a pivotal role in regenerating resin beads which, in turn, facilitate the removal of hardness ions from water. Although it doesn’t directly soften water, it is a crucial agent that assists in this process.

A Walkthrough of Salt Varieties

1. Solar Salt:


  • Source: Obtained from evaporated seawater, crystallized by the sun.
  • Pros: Highly soluble, dissolves rapidly, less prone to causing salt build-ups.
  • Best for: Systems suffering from frequent salt build-ups.

2. Evaporated Salt Pellets:

  • Source: Derived from raw salts that have been subjected to heat, removing all moisture.
  • Pros: Offers 100% purity, highly effective in treating hard water.
  • Best for: Those seeking a premium, highly effective salt option.

3. Rock Salt:

  • Source: Mined from underground salt deposits formed from soil erosion and other natural processes.
  • Pros: Affordable option, safe for continuous use.
  • Cons: Can lead to sediment build-up in the brine tank due to insoluble elements.
  • Best for: Budget-conscious users ready to manage potential sediment build-ups.

4. Potassium Chloride Pellets:

  • Source: Not a salt, but a healthy substitute for sodium-based salts.
  • Pros: A boon for those monitoring their sodium intake.
  • Cons: Can impact hypertensive patients.
  • Best for: Households with dietary sodium restrictions.

5. Hydrogen Peroxide:

  • Source: A chemical compound capable of softening water.
  • Pros: Also acts as a disinfectant, removing bacteria and germs.
  • Cons: Renders water too clean, potentially impacting taste.
  • Best for: Eco-conscious users focusing on water purity.
