Among the toxic chemicals you eliminate with an RO unit is arsenic. A disturbing study in the journal Environmental Health Perspectives found arsenic is prevalent in American drinking water and can contribute to skin cancer.
Chlorine is another prevalent toxin in tap water. A study in the journal Environmental Health Perspectives found chlorination disinfection byproducts in drinking water, such as trihalomethanes (THMs), could potentially contribute to low birth weight, preterm birth, birth defects, fetal deaths, and other adverse pregnancy problems.
An RO unit completely filters all natural and synthetic toxins, microbes, debris, and minerals. When you drink water filtered through an RO unit, you’re getting 100 percent pure, high-quality drinking water that tastes great.
My own view, after reading much of the expert opinion, is that the mineral content of water—either high or low—isn’t nearly as important as they would have you believe. That is, minerals in water are inorganic and hard for your body to use. You get most of your minerals from food, which provides organic, easily assimilated minerals.
The human body is a sophisticated instrument capable of adapting to a wide range of circumstances and capable of thriving in areas having water of high or low mineral content. As long as water is palatable, it’s within the body’s acceptable range.
The main issue with water is chemicals, not minerals. Whether water contains 30 or 3 parts per million calcium isn’t really significant, but the difference between 0.5 and 5 parts per million chloroform is of life or death importance.
