Our carbonating cylinders are an important part of your Sparkling Water Maker. They are made to fit your Sparkling Water Maker and contains colorless, odorless, incombustible gas, used to help create the bubbles. When you run out of CO2, you can either exchange your empty gas cylinder for a full one or use a spare cylinder.
With a cylinder exchange, you exchange an empty SodaStream cylinder for a replacement one and just pay the price of the gas. You can easily exchange your carbonating cylinder via home delivery or at a store near you.
If you wish to have a spare cylinder on hand, you pay for the cylinder and the gas, and there's no need to exchange an empty cylinder.
SodaStream recommends having at least 3 cylinders on hand, so you’ll always have bubbles and so you can exchange 2 at a time, taking advantage of the reduced shipping charge. Get your back-up CO2 cylinder here.
Note: The cylinders are, at all times, the property of SodaStream or its affiliates and provided for your use as a loan under the user license terms included on the cylinder sleeve.
