Physical water purifier – Physical water conditioners, so named because they physically alter the properties of hard water to reduce or eliminate limescale formation, are available in three different types – electronic, electrolytic, and magnetic.
An electronic water cooler, also known as an electronic descaler or an anti-lime remover, usually consists of a small electronic box and one or more coils wound around a pipe.
What They Do: Electronic air conditioners work by transmitting audio or radio frequency signals into the water through an induction coil wrapped around a pipe. This prevents the build-up of scale in the water pipes and over time reduces the existing scale. Softer limescale can still build up on showerheads, faucets, and other surfaces, but is easier to clean.
Advantages: Electronic decalcifiers are relatively inexpensive compared to other hard water treatment methods and offer an inexpensive solution to the limestone problem.
No piping is required, which makes installation very easy. And because nothing is withdrawn or added to the water, healthy minerals are retained and the water remains drinkable. You can even search online for more information about hard water treatment.
