Are existing bottles and cylinders compatible with the new SodaStream DUO™?
The SodaStream DUO™ Sparkling Water Maker can be used with our dishwasher-safe 1L glass bottle and our regular 1L Fuse bottle.
The 1L classic bottle, the 0.7L glass bottle (from the Crystal), the 0.5L bottle and My Only Bottle (0.5L) are not compatible.
With regards to cylinders, you can only use the SodaStream Quick Connect Cylinder with the SodaStream DUO™ Sparkling Water Maker. The blue screw-system cylinders are not compatible with the SodaStream DUO™.
