Q: Can I refill my own CO2 cylinder or have it refilled locally? +

A: No, SodaStream strongly advises against this. SodaStream licensed CO2 cylinders are filled with beverage-grade CO2 in compliance with exacting FDA standards for food and beverage safety. Your local filling station may not be in compliance with these standards and could possibly introduce toxins into your CO2. Furthermore, unauthorized filling machines may cause damage to the cylinder. Damaged cylinders will not be accepted for return by SodaStream. Any CO2 filling by parties other than SodaStream authorized filling stations violates the User License.

Q: Can a different company's CO2 cylinder be used? +

A: No, SodaStream provides a guarantee only for its own products. We are not responsible for the products of any other company, which may damage the Sparkling Water Maker. Only SodaStream cylinders with a nylon shrink wrap bearing the SodaStream (or Soda-Club) brand name should be used.

Q: How often will I have to replace my CO2 cylinder? +

A: This depends on how often you make sparkling water. On average, the cylinder will make up to 60 or 130 liters of sparkling water, depending on the size you have. This number could be more or less depending on the amount of carbonation used when making your drink.

Q: How should the CO2 cylinder be stored? +

A: It is important to always store the CO2 cylinder in a cool and dry environment. The cylinder must not be exposed to sources of heat (such as travel in the trunk of a car) or placed right next to a heat source such as an oven, stove or fireplace. Every cylinder is fitted with a unique safety valve which will safely release the gas in the unlikely event the pressure in the cylinder rises.

Q: What is the shelf life of the CO2 cylinder? +

A: The cylinder has no expiration date. As long as your cylinder is stored in a temperate environment, your CO2 will remain fresh and usable indefinitely, with no concern of spoilage.

Q: Is it safe to have a CO2 cylinder in my home or kitchen? +

A: Absolutely. SodaStream cylinders are manufactured to exacting specifications that include many unique safety features to protect consumers. Cylinders are safe at virtually any altitude (our customers in the Swiss Alps can attest to that!) and are specially equipped with a safety valve that will harmlessly release the gas in the unlikely event that the pressure within the cylinder rises above threshold levels. Please do not expose your cylinder to extreme heat (such as travel in the trunk of a car, or right next to an oven, stove or fireplace.) Please see above for more information on cylinder safety.

Q: Can I take my cylinder on a plane? +

A: We know it can be hard to leave your sparkling water maker at home, but SodaStream advises against carrying cylinders on an airplane. The Federal Aviation Administration (FAA) has restrictions that prohibit compressed gas cylinders in carry-on items as well as in checked baggage.

Q: How do I insert the cylinder into my sparkling water maker? +

A: Link to "easy as" module for cylinder insertion.
