Product advantages: The water purifier first appeared in the aviation industry and was developed to solve the drinking water problem of pilots. Its advantage is high effluent accuracy (nothing can pass except water molecules).
Disadvantages of the product: the water purifier does not retain beneficial minerals in the process of making water, resulting in more than 50% waste of tap water, but the water output is small, and it needs to be pressurized and electrified in the process of making water, which is not suitable for purifying a large number of domestic drinking water. The disadvantage is that the purified water is too pure and lacks trace elements beneficial to human body. A cup of pure water produces an average of 3 cups of wastewater, and electricity is also used.
The water purifier mainly adopts reverse osmosis membrane technology. Its working principle is to exert a certain pressure on water, so that water molecules and ionic mineral elements pass through the reverse osmosis membrane, while most inorganic salts (including heavy metals), organic substances, bacteria and viruses dissolved in water cannot pass through the reverse osmosis membrane, thus strictly separating the permeated pure water from the impermeable concentrated water; The pore size of reverse osmosis membrane is only 0.000 1 micron, that is to say, the water purifier does not retain beneficial minerals in the process of making water, resulting in more than 50% waste of tap water, but the water production is small and needs pressurized power supply, which is not suitable for purifying a large number of domestic drinking water.
Drinking pure water for a long time is not good for human health. Experts from the National Health Group pointed out: "For drinking water, the purer the better. Inorganic elements in water exist in the form of dissolved ions, which are easily absorbed by human body. Therefore, drinking water is an important way for people to ingest minerals. Pure water contains almost no minerals. Previously, it was mainly used for boilers in thermal power plants, washing in electronics industry, integrated circuit boards and so on. Drinking pure water should be cautious, especially for children, the elderly and pregnant women. "
Danish scholars have also reported that drinking pure water for a long time has a certain influence on the occurrence of dental caries in children. Some experts worry that drinking purified water for a long time will not only reduce the intake of beneficial elements, but also promote the excretion of beneficial elements as a kind of "hungry water".
So drinking pure water for a long time will cause the loss of nutrients in the human body. Over time, it will cause acid-base imbalance, reduce human immunity and affect health.
