How can filters takes out contaminants like VOCs but not the natural minerals?
Minerals are totally dissolved in solution and do not have an actual physical size; thus, the minerals pass through the filter unchanged. The materials used in a good drinking water are specially selected for their ability to react with the chemicals in the water but not with natural minerals. The ability to leave the natural, healthy minerals in while reducing harmful contaminants was a vital factor in the development of solid carbon block filters available in the market. The medical community has always maintained that certain minerals were essential for a healthy body, and a recent study in the Journal of the American Dietetic Association found that drinking water with high levels of beneficial, healthful minerals may reduce the risk of heart disease.
