What is Soda machine (home appliance)?

A soda machine or soda maker is a home appliance for carbonating tap water by using carbon dioxide from a pressurized cartridge. The machine is often delivered with flavorings which can be added afterwards to the carbonated water to make soda, like, for instance orange, lemon or cola flavours. Some brands are able to directly carbonate any cold beverage.

Examples of well known soda machine manufacturers are SodaStream of Israel, Drinkmate from the United States, and Aqvia by AGA of Sweden.

Soda machines can either be connected to a separate water tap in the house, or be a freestanding unit. Some refrigerators are delivered with a built-in soda machine.
