How does a cylinder exchange work?

Bubbles 101: Carbonating cylinders create the bubbles. After some time, the carbonating cylinder runs out of CO2. We offer an exchange in which you get a new carbonating cylinder in exchange for your empty one.

Once you order your exchange at, our Gas Refill program has 3 easy steps to get you back to bubbling:

1. We'll send you 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.
2. Place your empty cylinders in the same box in which you received your new cylinders and affix the label to the box.
3. Drop the package in the mailbox or at a local post office. You can also schedule a free USPS pick-up (if applicable to your location). The shipping is on us. Don’t wait too long to send back your used cylinders.**

    **Remember to send in your used cylinders after placing a cylinder exchange order. SodaStream must receive your used cylinder(s) no later than 30 days after placement of your exchange order. 
    If you do not return the empty cylinder(s) within this timeframe, or if you do not have any empty cylinders to return, or if the returned cylinder(s) is damaged, we will have to charge you an additional $15 (plus tax) for each unreturned cylinder.
