Because the water from the barrel water machine is replaced by air, and air replacement will bring in bacteria and microorganisms, which will grow moss at a certain temperature. It is suggested that bottled water and drinking fountains can avoid direct sunlight or places with high temperature sources.
Barreled drinking water should avoid direct sunlight, and it is best to use it up within one week after opening, and the water dispenser should be cleaned frequently.
Extended data
Barreled water is not suitable for direct drinking.
Food will go bad if it is kept for a long time, and water will go bad if it is kept for a long time, so people are usually used to eating fresh food and drinking fresh water, but bottled water is not suitable for drinking when it is fresh. The bottled water sold in the market, whether it is distilled water, reverse osmosis water, mineral water or other pure water, has been filtered and disinfected many times in the production process, but the final disinfection before filling usually uses ozone, so the bottled water just filled contains high concentration of ozone.
Although ozone has a strong disinfection effect, its strong oxidation is very harmful to human health. When ozone is inhaled into the body, it will destroy vitamin E in the skin, causing wrinkles and dark spots on the skin. In severe cases, it will also destroy the immune function of the human body and induce lymphocyte diseases.
So if you drink bottled water when it is "fresh", you will undoubtedly take poison with you. The best way is to leave fresh bottled water for 1-2 days, and then drink it after the ozone dissipates.
In addition, bottled water is not healthy water that can be safely drunk, especially bottled water that is used with drinking fountains. Faucets, water inlets and sewage outlets can easily let microorganisms and floating layers in the air enter the bucket, which will cause secondary pollution to the water in the bucket. In order to prevent drinking water that is polluted twice, the best way is to heat the water before drinking it.
