The magic behind the bubbles
The Fizz you love comes from a food grade CO₂ cylinder that is uniquely designed to be compatible with every Sodastream sparkling water maker. 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.
