Extended data:

At present, there are two technologies in the water purifier industry:

1, reverse osmosis. Reverse osmosis is recognized as the safest and most scientific water treatment technology in the world. The water from the reverse osmosis membrane is basically pure water, that is, only water molecules, so it is the safest, so the reverse osmosis machine is also called pure water machine.

2. Ultrafiltration. The filtration accuracy of ultrafiltration is second only to that of reverse osmosis, and the product is not pure water. Because the aperture ratio reverse osmosis of ultrafiltration membrane is greater, some manufacturers promote that ultrafiltration water purifier is a water purifier that can retain minerals, but in fact it is easy to avoid the heavy and light. Because it is not pure water, there may be bacteria, viruses and chemical pollutants in the water whose diameter is smaller than the pore size of ultrafiltration membrane.
