A water bottle is a container used to hold water for consumption. This allows an individual to transport or carry the bottled water from one place to another. A water bottle is usually made of plastic, glass, or metal, and so most can be recycled. Water bottles can be single use, returnable, or reusable. Water bottles are used for drinking water, carbonated water, mineral water or distilled water. Water bottles can be refilled with water or other fluids such as orange juice, iced tea or soft drinks.

The benefits of plastic bottles are that they are inexpensive, transparent, and shatter resistant. Depending on the specific plastic construction, however, there may be questions regarding the safety of some of the chemicals in the plastic and how those interact with the water.
Consumers have been warned about using warm water in some Polycarbonate bottles because of potential leaching of harmful chemicals into the water. One study concluded that water inside cloudy or scratched bottles is more vulnerable to contamination from phthalates or bisphenol A, commonly abbreviated as BPA.[1] Phthalates are being phased out of many products in the United States, Canada, and the European Union over health concerns. A 2010 report from the United States Food and Drug Administration (FDA) raised further concerns regarding exposure of fetuses, infants and young children to bisphenol A.[2] In September 2010, Canada became the first country to declare BPA a toxic substance.[3][4]
Metal water bottles have gained popularity. People often clean the bottles before refilling. Many companies of metal water bottles make them out of aluminum.
Some bottles now filter water by taking out some impurities and particulates from tap water.
