Order a refill to replace your empty gas cylinders with full ones.
Check compatibility
Receive your new, full cylinders in the box and replace them with the same amount of empty cylinders.
Attach the pre-paid return label to the exchange box and drop off at your nearest service point within 7 days to complete the exchange*.
Please make sure your empty gas cylinders are compatible with our refill service:
✅ 425g / 60L screw-in cylinder(s) approved for use with sparkling water makers
🚫 Damaged cylinder(s)
🚫 Soda Stream Quick Connect cylinders with the pink ring
If your cylinder is not compatible or you don't have any empty gas cylinders at home yet, please shop new Aarke gas cylinders here first, and come back for a refill later.
The reason for this is that we offer a gas cylinder refill at a cheaper price than if you would be buying a completely new cylinder.
Receiving back empty cylinders is essential for us to enable a smooth refill service for all our customers. Therefore, if you don't return the corresponding number of empty cylinders to us on time, we would need to produce new empty cylinders to fill with CO2 gas. This is why a charge for non-return applies if you decide to order a refill and receive full gas cylinders from us without returning empty cylinders back to us.
At the moment, 2 empty gas cylinders can be exchanged for full ones at a time. We are looking into providing the possibility of exchanging more cylinders at a time soon and you will see this option on this page once it's added.
We recommend buying 1 extra cylinder, so that you always have one full one to power your sparkling water maker. This way you won't have to wait until all your cylinders are empty to place a refill order.
The water will no longer become bubbly when you’re going through the usual carbonation steps. Before exchanging the empty cylinder, or putting it into the exchange box, you can double check that it is completely empty by depressing the center pin with a spoon. Any remaining CO2 will be removed then.

If you live in Germany, you can drop off the exchange box with the empty cylinders at your nearest DHL Service Point.
If you live in Austria, you can drop off the exchange box with the empty cylinders at your nearest DPD Service Point.
If you live in Switzerland, you can drop off the exchange box with the empty cylinders at your nearest Swiss Post Service Point.
Once you place the order and receive the order confirmation by email, the delivery time will then be 3-5 business days. When this new order is on its way, you will receive an e-mail with a tracking link.
*Please return a corresponding number of empty cylinders within 7 days from receiving new, full ones to avoid an additional charge of 15.5 € per cylinder for non-return.

Customers praised the refill service as "quick and easy" with "fast delivery." The circular exchange system works smoothly, though some noted refills are expensive and shipping could be faster. Post office drop-off has inconvenient hours. One shopper reported occasional cylinder pressure variations and adjustment needs. Overall, highly rated for convenience.
Seems to last as long as expected. Used daily since we got it (almost 6 weeks ) and just replaced with another one from Aarke which cost less with the empty cylinder.
Excellent
It always takes way too long for the cylinders to arrive.
Could last a little longer, otherwise great!
Easy to install. Brilliant
Great service and prompt delivery
Perfekt: 4Flaschen aus 2x2 zusammemgeklebt - Win Win für Beide!
Herzlichen Dank für diese Neuerung!
Je reste inconditionnelle de cette marque et facile avec le principe d’abonnement
Cylinder was quickly replaced.
ok
Amazing customer support!
It works great
Works perfectly
Arrived on time and easy to use
Arrived on time as expected
Does what it says on the cylinder.
Dommage qu’elle ne soit pas comprise dans l’achat
Just noticed that one of the tubes is not working as supposed to be. No gaz filled properly
They don’t last long, far too expensive to replace on a weekly basis
Not the easiest website to navigate but does the job!
All good, lasts for approx 5 weeks of use every day
Funktioniert
Great service glad now the Evri option is available
Effortless, reliable and fast.
livraison immédiate, en plein été !
je n'ai qu'un regret, ne pas avoir acheté leur appareil à eau gazeuze...
Delighted with product.
We are satisfy by the performance
Works fine
Livraison rapide.
Cartouche qui durent dans le temps. Envoi rapide pour la recharge et facilité de renvoyer les bouteilles usagées.
Very pleased with the new product / set-up!
It’s a good system but using a local exchange point (for example at supermarkets) would be a great improvement
