With a gas exchange, you return any empty SodaStream cylinder and just pay the price of the gas for a new cylinder. You can easily exchange your gas cylinder at one of our retailers, find a store near you with our store locator.

A spare cylinder is there so you never run out of gas. You pay for the license of the cylinder and the gas. SodaStream recommends having at least 3 cylinders on hand, so you’ll always have bubbles and so you can exchange 2 at a time. You can purchase spare gas cylinders here.
