A soda maker is a home appliance that uses carbon dioxide from a pressurized cartridge to carbonate tap water. Depending on the type, some soda makers can also provide fizz to juices and teas. Carbonated or sparkling water is not detrimental to your health. Sparkling water causes somewhat more tooth enamel erosion than regular water. Contrary to popular belief, CO2 is not a gas that is exhaled, but rather a liquefied compressed gas that is generated and transported or used as dry ice. In most instances, sparkling water is equally healthy as still water.
