Water purifier can use RO membrane because RO film can reverse osmosis membrane and heavy metal and toxic materials. RO reverse osmosis water purifier uses a reverse osmosis membrane filtration technology. Reverse osmosis membranes can filter selectively, its precision can reach 0.0001 micron, which can dissolve in water harmful heavy metals, scale, bacteria, and other contaminants and then become concentrated water to be discharged, the water molecules in the raw water preserved for drinking. After entering the human body, the part that human body can absorb has been preserved, non-absorbable metabolism excreted. Thus, reverse osmosis water purification equipment "kidney" in the world.
Ro film isnot suitable for water purifier, mainly because it is soft water. Oh, it is not good to health.
