CO2 Canisters

If you don’t have empty canisters to exchange right now, you can easily order an additional pack. Each canister order comes with a free refill box and a prepaid return label, making it easy for you to return them when you’re ready to refill. For smooth, uninterrupted use, we recommend keeping three canisters in rotation: one in your soda maker and two on their way for refilling.
