A water softener essentially removes water calcium in a process called ion exchange. The two most common ion-exchange methods are softening and deionization. Softening is used primarily as a pretreatment method to reduce water hardness before reverse osmosis processing. Deionization beads ion exchange either hydrogen ions for cations or hydroxyl ions for anions. The hydrogen ion from the cation exchanger will unify with the hydroxyl ion of the anion exchanger to form pure water.
Is Water Softening necessary? The answer is, that depends if you have hard water. Watch this video to find out how!
Purifiers reduce the amount of harmful chemicals and minerals such as Mercury, Lead Barium, Cadmium, Copper, and possibly Chromium-6 depending on what type and brand of purifier you use. There are many more minerals, and organic chemicals that are removed to both make your water taste better and potentially make it healthier for you to drink.
Depending on where you live you may want to consider adding a water purification system to your home. Arctic Air Services sells, installs, and maintains water softeners and purifiers. Who needs a purifier? If your is foggy, or a color other than clear. Municipalities occasionally clean piping which causes a rusty color, for example. Most municipalities use chlorine and other chemicals to treat water. Accessive chemicals in water can make it taste poorly. Water pumped from a well does not get tested on a schedule like municipal water. Purifiers may be added as a preventative measure.
