How much money can I save with a water softener?

you are based in a hard water area, there are plenty of reasons to install a water softener in the home. By process of ion exchange, the water softener will draw out the magnesium and calcium ions, the mineral content which makes it ‘hard’ in the first place. Having soft water flowing through your household will limit the accumulation of scale and scum and will actually provide treatment to areas where it has formed. You will also notice the water feels different, smooth and silky on the skin providing much more effective washes when combined with soap and washing detergents.

These are the benefits to your household, the things you will notice immediately. Gradually, you will also find yourself saving a lot less money.


Soft water is a solvent meaning it can dissolve other chemicals easily. Due to hard water’s mineral content, the water is more inert or less capable of sustaining a reaction. When combined with soap, it won’t create a proper lather leading to you having to waste more and more detergent just to get an effective clean. With soft water you can use a fraction of the amount and still gain a better clean, that will preserve the fabrics of your clothes.
