Carbonating cylinders create the bubbles. After some time, the carbonating cylinder runs out of CO2. We offer an online exchange in which you get a new carbonating cylinder in exchange for your empty one. When you order a gas refill at SodaStream.com, you just pay the price of the gas and are then sent a pre-paid shipping label to return your empties.
- We'll send your full cylinder(s) and include a prepaid USPS label with your order. Make sure to remove the label from the box and record the tracking number on the label for your records.
- Place your empty cylinders in the same box in which you received your new cylinders and affix the label to the box.
- Drop the package in the mailbox or at a local post office. You can also schedule a pick-up (if applicable to your location).
The shipping is on us. Don’t wait too long to send back your used cylinders.
Sparkle Note: Please remember to return an empty cylinder for each refill cylinder you have ordered. If you do not return the empty cylinder(s) within the allotted 30 days from the date your refill order was shipped, or if you do not have any empty cylinders to return, we will have to charge you an additional $15 (plus tax) for each unreturned cylinder.
