The Aarke sparkling water maker is designed from the inside out to become extremely compact. This is one of the secrets behind its good looks. Despite it's compact design, the Aarke machine features a unique safety system consisting of 3 independent safety valves.The lever both carbonates the water and automatically releases the pressure in the bottle. Just push the lever and hold it until you hear a buzz, then release it and unscrew the bottle from the machine.
NOTE - This machine requires a Co2 cylinder to function.
