Glass is the safest water bottle type because it’s chemical-free, made from natural materials, and dishwasher safe. When buying a glass bottle, there are a few things to look for: Soda-lime glass, which is the glass primarily used for windows, or traditional glass are also great options that are less expensive.

Another amazing thing about the blue glass…it increases the oxygen frequency of the water, allowing the water to stay fresher and cleaner longer in the bottle. These bottles do not get all funky inside unless you are putting other things than water in the bottle.

Cobalt glass—known as “smalt” when ground as a pigment—is a deep blue coloured glass prepared by including a cobalt compound, typically cobalt oxide or cobalt carbonate, in a glass melt. Cobalt is a very intense colouring agent and very little is required to show a noticeable amount of colour.

There are many different types of plastic glasses but only one kind contains BPA, and that’s polycarbonate. Glasses made from other plastics are considered BPA free because they don’t contain the chemical bisphenol-A, or BPA.

Although plastic water bottles do not contain BPA, they may contain potentially harmful bacteria after they are used. Reusing plastic water bottles is okay, but make sure to use soap and hot water to clean them after use, similar to how you would clean cups and dinnerware after eating.

Health Concerns As mentioned earlier, cobalt is generally safe–but not for the workers who extract it from the environment and are likely to be inhaling high and harmful amounts of cobalt on a regular basis.
