Are existing products (bottles, cylinders) compatible with the new DUO?

The 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 0.7L glass carafe (from the Crystal), the 0.5L bottle and My Only Bottle (0.5L) are not compatible.

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