Do you know the difference between nanofiltration water purifier and reverse osmosis water purifier?

The main difference between the two water purifiers lies in the core technology. Nanofiltration is a kind of membrane filtration technology between ultrafiltration and reverse osmosis, which can remove harmful substances in water, retain appropriate mineral elements and make the effluent safe and healthy. Reverse osmosis can remove almost all substances in water, including minerals, and the effluent quality is almost pure water.
