The CO2 cylinder behind every bubble
Every Sodastream sparkling water maker is compatible with a specific cylinder - either the Quick Connect Cylinder or the classic Screw-In Cylinder. The right one depends on your machine, but both give you the same refreshing sparkle you love.
The Quick Connect Cylinder, with its pink handle, clicks neatly into place - no twisting needed. It’s the simplest way to start sparkling in seconds. The classic Screw In Cylinder, marked with a blue seal, secures firmly at the back of your machine and delivers bubbles just as brilliantly.
Whichever type you have, each cylinder is cleaned, sealed, and tested to guarantee safe, consistent carbonation. That means you can enjoy reliable fizz, every time.
Not sure which CO₂ cylinder fits your machine? Use our cylinder guide to check compatibility and keep the bubbles flowing, hassle-free.
I love having the CO2 subscription, I have made changes to the amount of canisters and the frequency for delivery, it has always been a smooth process. Having the Sodastream unit and the continuous CO2 has never been easier to drink my sparking water with a twist of lime or lemon.
Love to get the CO2 I need shipped to me automatically. Tanks are always full and in perfect condition. Return label included. Process is so easy. I can change amount or timing any time I need.
Simple to set up account and send returns for free! I don’t know why I didn’t do this sooner!
Sodastream could not have made this processes any easier. I order 2 at a time and they send them in just a few days from time of order. The containers arrive in a box that I can use to return my used product AND they provide a prepaid return label. I signed up for an auto renew subscription and save even more money. Couldn’t be happier.
