This is a common question, there are several magnetic devices on the market which are designed to treat limescale. Right off the bat however a correction does need to be made. There is no such thing as magnetic water softening. Magnetic devices do not remove the mineral content from the water and thereby do not soften the water. We’ll cover what these systems actually do further into the article. The short answer is that most magnetic systems are a form of limescale inhibitor rather than a softener.
