What brand of water purifier is better How to choose a water purifier

Now the water purifier brand is very much, the quality of different brands is not the same, buy a water purifier before measuring the water quality of their own homes, and then choose the appropriate cartridge, and the cartridge to be replaced in the future, so the after-sales service must be good, or else the back is very troublesome.
