CO2 Canisters

If you don’t have empty canisters to send back right now, you can easily order a pack of new canisters. Every new canister order includes a free refill box and a prepaid return label, making it convenient for you when you're ready to refill. For seamless use, we recommend keeping three canisters in rotation: one in your soda maker and two on their way for refilling.
