The bottled water we drink is guaranteed by national security. This kind of water is the same as the pure water and mineral water we bought outside. Of course, others use tap water from their own homes. In this case, everyone needs to boil the water before drinking, so that some harmful substances in the water will be removed because of the high temperature. However, there may be some scale or something. In fact, everyone needs to worry too much. This kind of substance contains two elements, calcium and magnesium, which are beneficial and harmless to our human health.
However, for the sake of drinking water safety, some people will install a filter device in the water dispenser. Friends must pay attention at this time. We need to clean the drinking fountain and filtering device in time. If the filter device is used for too long, it should be replaced in time. Only in this way can the health of drinking water be guaranteed. If it is not cleaned up in time, it may breed a lot of bacteria, which is extremely harmful to our health. Therefore, as long as it is handled properly, the water from drinking fountains is harmless.
In some countries, the drinking water is not clean every year, which leads to some poisoning phenomena, and some can also induce physical diseases, such as gastroenteritis and so on. In fact, the bottled water we drink is very healthy and safe. As long as we drink boiled tap water, it is harmless to our health.
