It goes without saying that having access to clean drinking water is critical to one's health. We require a means to filter these toxins out of our drinking water as a result of pollutants and the degradation of natural resources. Hard water is best treated with a reverse osmosis (RO) water filter. Although a RO water purifier eliminates dissolved minerals and pollutants, it is ineffective against bacteria. The water filtering mechanism in a RO water purifier is simplified. A semi-permeable membrane filters the water. Toxins like lead, mercury, and chlorine are removed by RO water purifiers.
