CO2 Cylinders

SodaStream CO2 cylinders are totally safe to have in your home. They are manufactured to exacting safety specifications to protect our consumers and are safe at virtually any altitude (our customers in the Swiss Alps can attest to that!). Our cylinders are specially equipped with a safety valve that will harmlessly release the CO2 in the unlikely event that the pressure within the carbonating cylinder rises above threshold levels. Make sure to always store your CO2 cylinder in a cool and dry environment, away from direct sunlight. The carbonating cylinder must not be exposed to sources of heat (such as prolonged travel in the trunk of a car) or placed right next to a heat source such as an oven, stove or fireplace. 

While the CO2 in the cylinder does not expire, our cylinders need to be checked for quality assurance purposes by a certain date, which can be found at the bottom of cylinder. For best use, we recommend storing your cylinder at room temperature.

The body of our CO2 cylinders are aluminum while the valves are brass.
Enjoy the durability of our 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.
