How to lose? First of all, increased secretion of gastric juice and its acidity, the deterioration process of absorption of water in gastrointestinal tract, resulting in deformed intestinal mucosa. And the longer this drink "dead" water, the less remains in the body of calcium, phosphorus, and alkaline phosphatase. Feel like mineral starvation is simple – the body as a powerful computer, just takes distress as dizziness, fainting, and muscle spasms. And this is just the beginning, as long calcium loss threatens the destruction of enamel, frequent bone fractures and the development of various serious diseases. So far, based on experience and research specialists, we can safely assume that many of the diseases are in daily use contaminated water. Microfiltration, ultrafiltration, nanofiltration membranes can be used for water purification, but in the complex, because they do not have the ability to hold bacteria and viruses. They cost between 300 to 1,000 rubles. Reverse-osmosis systems are quite expensive from 20,000 to 60,000 rubles.

Household filters almost all water filters are based on coal cleaning. Absorbent carbon has a large surface area and is able to absorb large molecules of organic compounds, bacteria, and any mechanical particle, but this method of treatment does not protect against a variety of harmful substances. Moreover, For example, the filter-pitcher cartridges should be changed 1-2 times a month, otherwise there is accumulating rapidly multiply and harmful bacteria. For the sake of saving many neglected frequent replacement of cartridges. As a result, bacteria in the water at the outlet of the filter is greater than the input.
