Many people are fooled by the words “pure or purified water”.  The word pure conjures up images of crystal clean and refreshing drinking water.  First of all a water softener does not purify water. Purified water is actually acidic, dead or demineralised water.   Demineralised water is defined as water almost completely free of dissolved minerals as a result of distillation, deionizaton, or membrane filtration reverse osmosis, electrodialysis or other technology. 
 
The most common way to “ purify” water is a process called reverse osmosis.  Many of these units are housed under the kitchen sink—especially homes with a water softener.   These systems require costly replacement filters and a R/O system wastes 4-8 gallons of water for every gallon of water produced.  At a time when water is a precious commodity this is unacceptable.  Most importantly, reverse osmosis water carries little or no minerals.  The water is aggressive and will search for minerals and perhaps leech them from your body.  The story of some of the first groups to scale Mount Everest illustrates the need for minerals in our drinking water.   To stay hydrated, the hikers melted the snow into drinking water upon arriving at the top of the mountain.  Actually, the opposite happened and the hikers died of dehydration.  Because the water had not traveled down the mountain collecting minerals, it was truly demineralised water and lacked the healthy minerals necessary for the body to survive.

According to WHO, The World Health Organization, “drinking water should contain minimum levels of certain essential minerals.  Moreover, our digestive system absorbs some minerals more easily when ingested in water than in food.  Calcium is necessary for the body’s cardiovascular system; it constitutes one of the main elements in bone structure and is needed for blood coagulation and the normal functioning of the nervous tissue. “

Magnesium is also important to the human body because it maintains the integrity of the muscular tissue of the heart wall.  Our bodies need equal parts of magnesium to help the body absorb calcium  A few of the problems associated with magnesium deficiencies include depression, heart disease, osteoporosis, kidney stones, PMS and migraine headaches.

Remember, healthy water is water rich in minerals and low in chemical content.  Installing a LifeSource Whole House Water System makes certain the water you use is the cleanest, healthiest water available.  By filtering out the chlorine and leaving the healthy minerals intact, you are contributing to and protecting the health and well being of everyone in your home.
