How about the water purifier in the house? Is it true that it can be purified and drunk directly?
The waste water (throw away) is 2 cups ~4 cup. But I suggest you buy the R/O model of water, which can be regarded as pure water and almost no impurity. Brand is not important, it is important to filter mode and filter quality
The U/F model water purifier has no waste water, and the R/O model produces water, producing about 2/3~4/5, meaning that the water after filtration is 1 cups,
Water purifier is divided into several kinds, mainly in accordance with the filter mode, sub U/F mode and R/O mode, the two mode is the filter method and filter pore size is not the same,
