How To Choose The Right Salt For A Water Softener?

Take these factors into consideration when choosing water softener salts.

1. Manufacturing process: Water softener salts are different in terms of the way they are manufactured too. The manufacturing process affects the purity of the salt and the life of your appliances. Since solar salt involves sunlight, it is natural and does not involve a lot of processing.

2. Solubility: You must also consider the solubility of the salt that you plan to buy. Solar salt is known to have the highest solubility. Salts having high solubility do not leave a residue. The ones that leave a residue undergo a lot of maintenance, leading to mounting expenses. Solar water softener salt pellets dissolve faster and do not leave a residue.

3. Day-to-day purposes: Water softener salts help enhance the quality of water which we use on a daily basis for purposes like washing clothes and bathing. The best water softener salt will not cause damage to your skin when you have a bath, and to your clothes when you wash them. For this reason, look for salts that are of food-grade and free of questionable chemicals. Evaporated salt pellets are a recommended option for those looking for food-grade water softener salts. They exist in the form of pellets.

4. Maintenance: Opt for low-maintenance water softener salts because if water softener salts leave a residue, it can lead to maintenance issues. Solar salt dissolves slower when used, leading to maintenance issues like bridging. If you are looking for a salt that does not require much maintenance, choose water-softener salt pellets because they dissolve faster when added to the water.

How Do Water Softener Salts Work?

When salt crystals for water softener are added into water, an ion exchange process takes place where softener salts, such as sodium ions, replace the calcium and magnesium ions from the hard water and convert it into soft water. When this happens, the water’s efficiency is boosted along with reducing damage to pipes and appliances.
