What is the difference between a spare carbonator and an exchange carbonator?
Order an exchange carbonator when you have empties to return. SodaStream exchanges your empty one for a full one. SodaStream expects you to return an empty carbonator for every full exchange carbonator we deliver. Order a spare carbonator when you want to have more carbonators on hand. Keep a spare in the cupboard so you always have a carbonator ready to pop into your machine while you exchange your empties. Spare carbonators include a user license in the box.
