RO water filter uses reverse osmosis membrane technology. Its working principle is to exert certain pressure on water so that water molecules and ionic mineral elements can pass through the reverse osmosis membrane, while most inorganic salts, organics, bacteria, viruses, etc dissolved in water can not pass through the reverse osmosis membrane, so that the permeated purified water and the waste water can be strictly separated.

The pore diameter of the RO membrane is only 0.0001 μ m, while the diameter of the virus is generally 0.02-0.4 μ m, and the diameter of the ordinary bacteria is 0.4-1 μ m, so you can safely drink water from the RO water filter.
