Are existing products (bottles, cylinders) compatible with the SodaStream DUO™ Sparkling Water Maker?

The SodaStream DUO™ Sparkling Water Maker can be used with our dishwasher-safe 1L glass carafe and our regular 1L Fuse bottle.

The 1L classic bottle, the 0.8L glass carafe (from the Crystal), the 0.5L bottle and My Only Bottle (0.5L) are not compatible.

The SodaStream DUO™ Sparkling Water Maker can only be used with the SodaStream Quick Connect Cylinder. The blue screw-system cylinders are not compatible with the SodaStream DUO™.
