The shelf life of bottled water is generally only 15 days. If it is unopened bottled water, it can be stored in a cool and dark place for up to 3 months. Barreled water is generally sealed pure water, so the shelf life is related to the air it contacts. Even the water put on the water dispenser should be drunk within 15 days. The water dispenser has the function of storing water, and it is easier to accumulate bacteria after long-term use, so it should be drunk as soon as possible.

Precautions for drinking bottled water

It should be noted that consumers can try to turn the bucket upside down, which should not leak. When the bucket is pulled out of the drinking machine, it should be plugged in again. Qualified drinking water should be colorless, transparent, clear, odorless, odorless and invisible. Aquatic products with yellow color, turbidity, flocculent precipitation or impurities and odor must not be drunk.

Bottled mineral water is best placed in a dark, ventilated and cool place to avoid exposure to the sun. At the same time, we should be alert to the secondary pollution of the water dispenser and pay attention to cleaning the water dispenser regularly.
