To change a SodaStream CO2 cylinder, match the connection to your machine, remove the empty cylinder as its manual directs, and secure a compatible refill. If you're searching how to change SodaStream CO2, first check whether your machine takes a pink Quick Connect cylinder or a blue screw-in cylinder.
A compatible refill should fit without force and sit securely before you carbonate water. Choose the pack around your machine model, how often you make sparkling water, and whether you want a return option for empties.
How do you change a SodaStream CO2 cylinder?
Use your machine's manual for the release and installation steps, because they vary by model. The general process is to open the cylinder compartment, remove the empty cylinder, and secure a compatible full one.
- Check your machine model and confirm the cylinder type before starting.
- Turn off or unplug the machine if the manual instructs you to.
- Open the cylinder compartment and release the empty cylinder as shown in the manual.
- Place the replacement in the compartment and secure it as directed.
- Close the compartment and follow the machine's instructions before carbonating water.
Don't force a cylinder that resists removal or won't sit securely. Stop and check the manual or contact SodaStream support.
How do you choose the right SodaStream CO2 refill?
Buy the cylinder type your exact machine uses, then choose a pack size that suits your refill routine. Pink Quick Connect and blue screw-in cylinders have different fittings and are not interchangeable.
SodaStream lists its pink Quick Connect cylinders as compatible with models including Terra, ART, E-Terra, E-Duo, Aqua Fizz, Enso, and Gaia. Confirm your own model in its manual, since a familiar brand name alone doesn't tell you which connection it needs.
If you have a Quick Connect machine, the SodaStream 2-pack includes two 60L cylinders and a return box and label for two empties. It suits buyers who want a return option included with the pack.
The SodaStream 3-pack gives you three 60L Quick Connect cylinders. Choose it if you make sparkling water often and want more spare cylinders ready; skip it if two cylinders are enough or you use a different connection.
Simpli Soda sells a two-pack of 60L Quick Connect cylinders and names ART, Terra, and Duo among its compatible machines. It may suit buyers whose model matches those systems; skip it if your machine uses a screw-in cylinder or you need a different pack arrangement.
Each cylinder is described as making up to 60 liters, though actual output depends on carbonation level and the machine. For more options and compatibility details, see our guide to Quick Connect CO2 cylinders.
How to change SodaStream CO2 when you have a blue screw-in cylinder
Use a blue screw-in replacement only if your machine is designed for that system. Its connection differs from the pink Quick Connect fitting, so don't try to adapt one type to the other.
Check the cylinder in your machine and find the model label if you don't know which system it uses. Our guide to SodaStream models and their differences can help you identify the machine before you order.
What should you check before installing a replacement?
Check the cylinder type, machine model, and connection before you start the swap. Follow the handling and installation instructions that came with your machine and replacement cylinder.
Keep the cylinder away from heat and handle it as its manufacturer directs. Don't install one that appears damaged or has a connection that doesn't match your machine.
A secure fit matters. If the replacement won't sit in place or the compartment won't close as expected, remove it only as directed and recheck compatibility instead of applying extra pressure.
What common cylinder-change mistakes should you avoid?
The most common mistake is buying or forcing the wrong connection. Check your exact machine model before buying, then stop if the cylinder doesn't fit the way the manual describes.
- Don't assume every SodaStream machine uses the same cylinder system.
- Don't force a Quick Connect cylinder into a screw-in machine, or the reverse.
- Don't skip the manual's release and installation steps.
- Don't use a cylinder that appears damaged.
- Don't assume a machine problem means the cylinder needs more pressure; check that the refill is compatible and seated correctly.
If the cylinder is secure but the machine still won't carbonate, use our SodaStream troubleshooting guide for other checks. If you're trying to estimate when you'll need another refill, see how long a SodaStream CO2 cylinder lasts.
What should you do with an empty cylinder?
Use an exchange or return program that accepts your cylinder type, and follow its current instructions. Return steps differ by provider, so check the rules before packing or shipping an empty cylinder.
The SodaStream 2-pack described above includes a box and return label for two empties. SodaStream says its program accepts certain 60L cylinders from other brands, but check the program's instructions for eligibility and how to register your return.
Keep the cylinder upright and follow the return provider's packaging directions. Don't put it in household recycling unless local guidance specifically allows that type of cylinder.
Which SodaStream CO2 refill should you choose?
Choose by connection first, then by how many spare cylinders you want and whether you need an included return option. The right choice is the one that matches your machine and refill routine.
- Pick the SodaStream 2-pack if you use a compatible pink Quick Connect machine and want two cylinders with a return box and label for two empties.
- Pick the SodaStream 3-pack if your Quick Connect machine matches and you want three cylinders on hand.
- Pick the Simpli Soda 2-pack if your Quick Connect model is among the compatible machines it names, including ART, Terra, and Duo.
- Skip all three if your machine uses a blue screw-in connection or you can't confirm compatibility yet.

Follow the model-specific steps and stop if the cylinder does not fit or lock into place.

How do I know if my SodaStream uses a pink or blue cylinder?
Check the cylinder in the machine and confirm the type in your manual. Pink cylinders use Quick Connect, while blue cylinders use a screw-in connection.
Color can help you identify the system, but verify compatibility with your exact machine model before buying or installing a replacement.
Can I use a Quick Connect cylinder in a screw-in SodaStream?
No. Quick Connect and screw-in cylinders have different fittings, so use only the type specified for your machine.
Check the model manual or SodaStream support if you're unsure.
A cylinder that won't fit securely should stay out of the machine.
What should I do if a new SodaStream cylinder does not fit?
Stop and compare the cylinder type with your machine model and manual. Quick Connect and screw-in fittings are not interchangeable, and forcing a mismatch can damage the connection.
If the cylinder appears compatible but still won't secure, leave it out and contact the manufacturer for guidance.
