FAQ
Is it safe to have carbonating cylinders in my home and how should they be stored?
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 gas 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.
Will my carbonating cylinder expire?
While the gas in the CO2 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.
What are your CO cylinders made from?What are your CO cylinders made from?
The body of our CO2 cylinders are aluminum while the valves are brass. Enjoy the durability of our cylinders!
What's the difference between exchange versus back-up carbonating cylinders?

Bubbles 101: Our carbonating cylinders are the heart of your Sparkling Water Maker. It perfectly fits your Sparkling Water Maker and contains colorless, odorless, incombustible gas, used to help create the bubbles.

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 carbonating cylinder via home delivery or at a store near you.

A spare cylinder is there so you never run out of gas. You pay for the cylinder and the gas, and there's no need to return 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.
