How is the quality of Yuemei water purifier?

Normal water purifiers can filter bacteria, and the principle is that the filtering accuracy is far less than the size of bacteria. The so-called resin water purifier on the market is not good. This water purifier is actually a water softener, which can only do ion exchange and has nothing to do with filtering bacteria. The safest is ro reverse osmosis water purifier, which has extremely high filtration accuracy. The beauty of this piece is not bad, at least it has continuous technological innovation to meet various water quality needs.
