As its name suggests, the Duo is the first sparkling water maker that is compatible with both glass and plastic bottles. This allows SodaStream 1L bottles (fillable up to 0.86L) Fuse and Duo to be easily inserted into the titanium container (maximum safety) without any screws. Not only can fresh mineral water be made more quickly, but the Duo also operates significantly quieter than its predecessors. With its standardized height and front operation, the Duo fits under any standard kitchen cabinet and, with its elegant design, is a timeless kitchen companion.

Cool design. No screws: neither for the cylinder nor the bottle. Safe CQC cylinder system. Suitable for glass carafes and plastic bottles. Dishwasher-safe bottles. Fits under any standard kitchen cabinet. CQC cylinder - Quick Connect CO2. Click in and start sparkling for up to 60 liters of homemade mineral water. The CQC cylinder can be easily clicked into the device without lengthy screwing. The Quick Connect system was developed by SodaStream for quick and safe cylinder changes. This smart innovation is patent-pending and has been tested by the Swiss Safety Center. Important note: The CQC cylinder can only be used with SodaStream models Duo, Terra, and Art.
