Exchange and Refill Your CO2 Cylinders

Refilling your cylinders is the most cost-efficient and sustainable way to bubble. With every exchange, your empties must pass SodaStream's Triple Quality Control - a rigorous sterilisation and inspection process - before they’re refilled with fresh dietary-grade CO2. By reusing cylinders you are keeping our planet clean, saving money, and ensuring that you and your family are making the sustainable choice to reduce single-use plastic waste.
