Salt-free systems crystalize the hardness minerals so scale will not form when the water flows through your water pipes. Essentially, the hardness minerals are still in your water, but they are in a different chemical state. In summary, a saltless water softener alters your water to reduce the effects of hard water.

Salt-based softeners and salt-free conditioners are similarly priced, but salt-based softeners are more expensive to operate in the long run. With a salt-based softener, you'll need to pay for salt top-ups. While the cost of salt comes to less than $50 per year, it's still $50 more than you'll spend on a water conditioner.

Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of …

A salt-free water softening unit does not use salt to remove hardness-causing minerals such as calcium and magnesium. Instead, it changes the structure of hardness-causing minerals, so they don't form scale. A traditional salt-based water softener uses a process called ion exchange to remove hardness-causing minerals.

Hardness: Hardness refers to the ability of a mineral to resist scratching. The Mohs scale of hardness, which ranges from 1 (the softest) to 10 (the hardest), is commonly used to measure the hardness of minerals. For example, talc has a hardness of 1, while diamond, the hardest mineral, has a hardness of 10.

The result is water with zero mineral hardness but a slight increase in sodium content. Water softeners typically contain a mineral tank filled with small resin beads. Hard water runs through the resin beads, and the sodium ions are swapped for the hardness minerals. After this ion exchange process, the water leaving the softener system is soft.
