What's the difference between CO2 exchange VS. Back-Up CO2 cylinders (spare cylinders)?

When you first purchase a SodaStream Sparkling Water Maker, a compatible cylinder is included in the box. When the cylinder is used, please return the cylinder to either SodaStream or an authorized SodaStream distributor in exchange for a full cylinder, for the price of a CO2 refill only. The license will continue to bind the use of each subsequent SodaStream cylinder.

You can purchase a spare cylinder so that you never run out of CO2. For every spare cylinder purchased, you pay a licensing fee to use the cylinder and for CO2. We recommend having at least 3 cylinders on hand, so you’ll always have bubbles and so you can exchange 2 at a time. Get your back-up CO2 cylinder here.


If you find that you have accumulated more cylinders than you would like to exchange, you can return the empty cylinders to SodaStream or an authorized SodaStream distributor, without exchanging it for a full one. You will be entitled to a return fee of $1 or local equivalent. Click here for more information on our cylinder return fee policy.
