How long does it take to drink bottled water before it is safe

Whether in offices or homes, people have started using bottled water. Bottled water is not only hygienic and clean, but also rich in trace elements that are healthier and can achieve the effect of health care. However, different brands of bottled water are slightly different, and the trace elements they contain may vary slightly, but we can all use them with confidence. So, what is the general shelf life of bottled water?

1. Shelf life of bottled water after opening

Bottled water becomes contaminated when it comes into contact with bacteria after being opened. These bacteria mainly come from hands, cups, water dispensers, etc. If you touch the seal of bottled water with your hand, it is easy for bacteria to remain on the mouth of the barrel; if the cup is not cleaned frequently, bacteria will remain; water dispensers are the places where bacteria are most likely to breed, because the impurities and minerals in the bottled water will be precipitated in the inner tank of the water dispenser, which will seriously affect the quality of drinking water over time.

The shelf life of opened bottled water is only 15 days at most, and the best drinking time is 5 to 7 days. If opened bottled water is left for more than half a month, although the taste may not change, the bacteria content will exceed the standard. Therefore, we should not drink bottled water for too long. If the water is not finished within 15 days, do not drink the remaining water. Use it for other purposes and do not waste it.

2. Shelf life of other water

Shelf life of boiled water:

Only about 1 day. The 1 day mentioned here refers to the water filled in the thermos. But boiled water only lasts about 16 hours.

Purified water shelf life:

Generally, purified water does not contain bacteria when it is packaged, but opening it for the second time will cause contamination to the purified water, so if the purified water is more than 5 days old, it is best to heat it before drinking.

Mineral water shelf life:

Unopened mineral water has a shelf life of about one year, but after opening it only has a shelf life of about 5 days. However, since mineral water contains a large amount of minerals, it cannot be heated, otherwise the minerals will precipitate and lose its health-preserving effects. Therefore, mineral water is not suitable for drinking more than 5 days after opening.

Magnetized water shelf life:

Magnetized water is divided into artificial magnetized water and natural magnetized water. Generally, artificial magnetized water is treated by a magnetizer and has weak magnetism. The shelf life of this water is no different from that of purified water.
