From the perspective of healthy drinking water, avoid drinking "thousand boiling water" and "yin and yang water". The so-called "thousand boiling water" means that repeated boiling water will produce nitrite in water, and drinking this water for a long time is easy to form kidney calculi in human body; "Yin and Yang water" refers to the water mixed with raw water and boiled water, and the other is to burn the mixed water once, which is easy to cause intestinal infectious diseases. These two kinds of water are found in traditional drinking fountains, so my family has abandoned this drinking fountain for a long time now.
By the way, I'd like to talk to Amway about the Wilson instant water dispenser that I just entered recently. At first, I was attracted by its highly recognizable appearance. After some comparison and understanding, I found that its material selection and function are better. Stainless steel thick film is used for heating, which does not produce scale and odor. This is very important for me who usually like to make tea! In addition, there are 3-second-speed heating and 7-speed temperature control functions. Some brands can also do it with two-speed heating, but there are not as many temperature control gears as other brands, and there are 3-speed water selection, which is not afraid of wasting water. Equipped with two adapters and hoses, it can connect mineral water, baby water and bottled water. It can be carried at home and during travel. It's a little bigger than my Apple plus, and it's easy to carry, and it's also very convenient to take the baby out to soak milk. "
