We generally do not recommend that water filtered by ultrafiltration water purifiers be used for direct drinking. The ultrafiltration membrane at the core of ultrafiltration water purifiers has a filtration precision of 0.01 microns. In other words, it can remove impurities in the water with a diameter greater than 0.01 microns. Some bacteria are blocked outside the membrane, but some heavy metals and bacteria and viruses smaller than 0.01 microns are directly "released".
Ultrafiltration water purifiers can retain minerals and trace elements that are beneficial to human health to a certain extent (but some harmful ones will also exist), so unless the water quality in your area is relatively good, the ultrafiltration water purifier will It is still recommended not to drink water directly.
If you need direct drinking water, you still have to rely on a reverse osmosis water purifier. Many of the bottled water we buy in stores are filtered using the reverse osmosis process. The reverse osmosis RO water purifier is equipped with an RO membrane with a filtration accuracy of up to 0.0001 micron. The filtered water is pure water and can be drank directly.
