Do not be fooled!!! While a lot of these devices do exist, only water softeners soften water. In the industry, these magnets are referred to as “Descalers”, not softeners. They may be effective in certain applications as descalers, but they do not remove the hardness of the water. All of the benefits of softened water are forfeited. These items are sold with testimonials and a money back 90 day guarantee, but there is no scientific evidence to support their claims. If it sounds too good to be true, then it most likely is!
