Is bottled water better or water filtered by water purifier? Why?

Bottled water is good. Bottled water should be used up within one week after opening, otherwise there will be the risk of secondary pollution. The water dispenser should be cleaned and disinfected at least once a month, and once every half month in summer. If it is not disinfected regularly, it will breed bacteria and viruses, and long-term drinking will be harmful to the body.

Pure water or mineral water treated by modern industrial technology (reverse osmosis, electrodialysis, distillation, resin softening, etc.). ) through the filling production line, the product is filled into a PC barrel to obtain the product. Barreled water is divided into pure water, mineral water and mineral water (made by artificially adding minerals to pure water).

Calculation method of water purifier:

It should be noted that the total output of the water purifier is related to the water quality of the water purifier. If the water quality of the water purifier is good, the total water output will increase; if the water quality is poor, the total water output will decrease, and the service life of the corresponding filter element will be shortened.

After long-term use, the water output of the water purifier will gradually decrease, but the water quality is still qualified, so you can use it with confidence.

After the water purifier is used, the ultrafiltration membrane filter element should always be kept wet. If the ultrafiltration membrane filter is dry, the water yield will drop sharply and cannot be recovered.
