Soda Sense CO2 Refill Exchange Service

You receive a pre-paid shipping box where you place your empty CO2 canisters. Once you drop the box in the mail, Soda Sense processes your return and sends out full, recycled canisters to your doorstep, keeping your carbonation supply consistent without needing to visit a store.

The service supports both standard threaded (screw-in) canisters and modern quick-connect cylinders. As long as your machine uses one of these two industry-standard connection types, the canisters will be compatible.

Each canister is rated to carbonate up to 60 liters of water. This yield can vary slightly depending on your personal carbonation preference—specifically, how many times you press the button for fizz.

The program is designed to handle multiple canisters per shipment. It is generally most efficient to wait until you have a few empty cylinders on hand before sending them back, which minimizes the number of trips you need to make to the post office.

By using this exchange program, you are participating in a closed-loop system that reuses metal cylinders. Each canister you exchange effectively offsets the need for up to 170 single-use plastic bottles, significantly reducing your household waste.
