Why is the hotel full of mineral water?

There is no air left in it to ensure the quality.

The hotel's mineral water is full because there is no air in it to ensure the quality. Mineral water is very low in cost, so it can't be filled with carbon dioxide or inert gas, so it can only be filled in special packaging.

Mineral water is unpolluted underground mineral water that gushes naturally from deep underground or is exposed artificially.
