Which is better? UF filtering or ro filtering water purifier. At present, there are basically two types of water purifiers in the market, one is ultra filtration water purifier, and the other is reverse osmosis water purifier. The biggest difference between the two types of water purifiers is the difference in filtration precision. Ultra filtration water purifiers use ultra filtration membranes, which can achieve a filtration precision of 0.01 microns, and can filter out most of the impurities in the water, but cannot filter out water alkali, belonging to mineral water. The core component of the reverse osmosis water purifier is RO membrane. The filtration accuracy of RO membrane can reach 0.0001 μ m, and basically only water molecules can pass through. Therefore, the basic purified water obtained after filtration will not produce scale in the kettle. As for this choice, it can be decided according to your local water quality. If the local water quality is good and the water alkali is few, you can choose ultra filtration water purifier, which is economical and affordable. If the local water quality is poor and the water alkali is too high, you can choose reverse osmosis water purifier. We also have hot and normal water dispenser, under sink water purifier for your choice. UF filtration Keep beneficial minerals,No waste water.
