Bottled water cannot be drunk for more than 48 hours after opening, and bottled water cannot be drunk for more than 10 days after opening. If the purified water is opened for too long, the bacteria in the water will multiply in large numbers, which will easily cause symptoms such as diarrhea after drinking. At the same time, it is necessary to avoid putting the purified water in direct sunlight, and the increase in temperature will also increase the reproduction speed of bacteria in the water.

Matters needing attention in drinking pure water

Drink pure water in moderation. The pH value of pure water is weakly acidic, but most people are suitable for drinking weakly alkaline water. Especially for the elderly, children and infants, it is not suitable for drinking pure water in large quantities for a long time. Pure water should be drunk alternately with mineral water.

Clean and disinfect drinking fountains regularly and comprehensively. It is best to be cleaned by professional cleaners, once every three months in winter and once every one and a half months in summer. Because the bottled water is put into the water dispenser, it is communicated with the water reservoir of the water dispenser and indoor air.
