One CO2 cylinder used to power the Aarke Carbonator will provide you with around 60 refills of our PET Water Bottle. So, if you're regularly drinking sparkling water, the Aarke home carbonation system can reduce the size of your recycling pile by almost 100 small single use plastic bottles per cylinder.

Compatible with 400-425g/60L CO2 cylinders from Sodastream (not Quick Connect), AGA, Linde, and many other standard gas cylinders approved for use with sparkling water makers. CO2 gas cylinders are widely available on Amazon. Depending on your location, you can also buy and refill these gas cylinders at your local supermarket.
