Hill water purifier is a strontium-rich mineral water that can be filtered and drunk immediately, that is, a strontium-rich mineral filter element is added to the traditional 5-stage filter element and 5-stage activated carbon.
What is more satisfactory is that this water purifier produces water much faster than at home, and because there is no old water in the machine, you can drink the first drop of water directly when you open it, which can save a lot of time, and the water output is better than expected, without delaying aunt's cooking time.
The water droplets before filtration turn the reagent into green, which belongs to neutral water, and the water droplets after filtration turn the reagent into blue-green, which is in line with the official statement.
