a) Salt-Based Ion Exchange Softener: This type of water softener cycles household water through two tanks: one with special resin beads and the other filled with brine. It works on the principle of ion exchange, softening hard water by substituting sodium (salt) for hard minerals such as calcium, magnesium, and iron
b) Salt-Free Water Softener: A salt-free water softener regenerates with a potassium-chloride salt substitute rather than sodium. This type of unit may be a better option for people who are concerned about salt intake. This type of water softener is actually a descaler—it doesn’t reduce the hard water minerals but rather prevents minerals from being deposited as scale to the surfaces of water-using appliances and pipes. The general consensus is that this type of water treatment is better than no water softener at all, but not as effective as conventional water softening
2. Salt free Conditioners with Electromagnetic waves: The device produces an electro-magnetic field. As soon as the water passes through this field, it changes its adhesion properties. Rather than depositing on pipes and appliances.
Electromagnetic waves are created that alter the calcium crystals properties seen in hard water. The waves do not have any effect on the taste of the water, and you will not know the system is even on and working.
Compatible with all kinds of pipes, which include:
- Stainless steel
It is IMPORTANT to know that it does not really remove hard water minerals from the water supply. These minerals that’s healthy will still be there. They only won’t stick to your appliances or pipes. These powerful magnets also create de-gasification, which decreases the taste and smell of chlorine. Water becomes wetter and softer. It reduces surface tension of water by increasing solubility.
