We always refill 2 cylinders at a time. So when you are ready to exchange always pack 2 empty cylinders into the exchange box before sending it back to us.
Tips: we recommend owning 3 cylinders in total so you always have 1 in our carbonator, while we're refilling the other 2.
The water will no longer become bubbly when you’re going through the usual carbonation steps.

The food grade CO2 used in our cylinders is exclusively produced from renewable resources. This means that our CO2 comes from sources already in the eco-system, not adding unnecessary CO₂ to the atmosphere. Click here to learn more.
