With the array of choices we have for softening hard water, it can be difficult to decide which method will work best. Therefore, cost is one factor to consider as well as how the unit is set up, its size and its softening capacity.

Testing water hardness is as simple as getting a water test kit from a pool supplier or an establishment that sells water softener systems. Water hardness is measured in grains per gallon (GPG), parts per million (PPM), or milligrams per liter (MG/L). Water that measures 3.5 to 7 GPG is considered hard water.

Magnetic water softeners rely on the use of ordinary magnets. The magnets are mounted opposite one another, either outside or inside a water pipe. The water flows between these magnets, through the magnetic field, which affects the ions. A chemical reaction takes place, altering the molecular structure of hard water minerals.

This reaction will take one of two forms: Magnetic or electrostatic. During a magnetic process, the collision process of magnesium or calcium ions is sped up. This takes place in a cool environment, and as a result, lessens the buildup of scale. In contrast, during an electrostatic process, an electrical charge forces the ions to repel one another. The ions are not able to bond and form scale. The main functions of magnetic water softeners are applicable in heating and cooling.

Magnetic water softeners are the subject of much debate, and magnetic water softening systems cannot usually be purchased via retailers. The effectiveness claims made by manufacturers are often backed up by anecdotal evidence, though scientific studies have been done. The outcomes are inconclusive. While it is acknowledged that magnetism does, indeed, alter the hard minerals, the exact effects on the water are unclear. The consensus is that scale formation can be reduced by magnetic treatment; however, the reduction of scale appears to be minimal, roughly 10 percent. An advantage to using a magnetic water softener is that it is a non-chemical treatment.

When it comes to magnetic water softeners, being an educated consumer is the best policy. Explore different types and manufacturers. Compare prices. Other things to consider are what type of environment the water softener will be set up in, the size, installation, and construction of the unit.
