Shungite has the ability to clean water from almost of all organic compounds (including pesticides), metals, bacteria and harmful microorganisms. Commercial use of Shungite filters started back in 1990's, during that time there were conducted many experiments and studies on Shungite influence on the human body. Scientists came to conclusion that Shungite water is absolutely non-toxic. It was also proven that shungite water can be used without any prior boiling! The water has strong antibacterial ability. During the experiments, water was contaminated with streptococcus of groups A and D. Experiment showed that only after half an hour in Shungite water the concentration of streptococcus group D decreased by the factor of 100 and group A by the factor of 900! Shungite cleans water of various chlorine compounds, nitrates, copper, magnesium, iron, cleans up visually dirty water, eliminates sour taste.
