Among all kinds of water bottles, glass water bottles are the healthiest and safest.
The first choice for drinking bottles should be glass water bottles, especially for office and home users. The glass is not only transparent but also the healthiest and safest of all materials. Glass water bottles are made of inorganic silicates, which do not contain organic chemicals in the process of firing. When people drink water or other drinks with glass water bottle, they do not need to worry about the chemical substances being drunk into their stomachs. Moreover, glasses have smooth surfaces and are easy to clean. Bacteria and dirt are not easy to breed on the wall of glasses, so drinking water with glass water bottle is the healthiest and safest.
The only thing to note is that glass water bottles are most afraid of thermal expansion and contraction. Glass water bottles that are too low in temperature (such as those just taken out of the refrigerator and just brought in from the cold outdoors) should not be filled with hot water immediately in order to prevent bursting.
