Aarke carbonators are compatible with CO2 cylinders from Sodastream, AGA, Linde, and many other standard 400-425g/60L gas cylinders approved for use with sparkling watermakers.

If you’re shopping in Australia or New Zealand (where Aarke products are only available at local retailers), we recommend Australian Sodastream and Soda King cylinders.

400-425g/60L gas cylinders are widely available on Amazon.

Depending on your location, you can also buy and refill these gas cylinders at your local supermarket.

Yes. This is true that in some markets you can now find the Sodastream CO2 cylinder, which can produce up to 80L of sparkling water. It is still compatible with our Carbonator if its volume is indicated as 425g.

However, please note that if you prefer a medium to a high levels of carbonation, the 80L canister will still provide you with approximately 60L of sparkling water.

No–for safety reasons it isn’t possible to use Aarke Carbonator 2 or 3 with a glass bottle as it would require a solid case around the bottle, protecting it in the event of breakage (due to improper use, defect, crack or anything compromising the material).

Please only use our Carbonator with the original BPA free, tasteless PET Water Bottle, which comes included with every Carbonator.

Our bottle has a special marked filling line to help avoid excess water flowing into the spill tray during carbonation.

The capacity of the bottle up to the filling line is 80 cl or 800 ml and this is how much water can be carbonated at once. The capacity of the whole bottle equals approximately one litre.
