How do various types of water softeners work?


A water softener helps remove calcium and magnesium metal ions from water. Once these are removed, the water is soft, and it does not cause scaling in pipes, fittings, and appliances like washing machines, etc., which increases their lifespan. Soft water is good for your plumbing and fittings and great for your skin and hair. If you’ve ever wondered how water softeners work, then read below to find out.

There are three main types of water softeners – Electric, Magnetic, and Salt-based water softeners.

How Salt-based Water Softeners Work: Salt-based water softeners work on the principle of ion exchange. Resin beads in the mineral tank in a salt-based water softener carry a negative charge and attract the metal ions, which have a positive charge. Salt-based water softeners are the most popular type of water softeners used in households as they are easy to install, give great results, and are cost-effective.

How Magnetic Water Softeners Work: A magnetic water softener consists of magnetic field units around your main water supply. When water passes through the magnetic field, hard water ions are attracted and separated, while soft water flows inside. Unlike salt-based water softeners, you don’t need to worry about replacing the salt with magnetic water softeners.

How Electric Water Softeners Work: An electric water softener system consists of 2 opposite electric charges rolled over your main water inlet. This creates electromagnetic waves which attract calcium and magnesium ions and break them down. The result is soft water that flows into your main inlet.

Having a water softener installed at your home comes with benefits like extended life of appliances, plumbing, sewer system, clothes, utensils, and better hair and skin health. So, if you are looking for a water softener, read our detailed guide on the best water softeners out there:
