The Cylinder Loop is our smooth, circular set-up to help ensure you never run out of gas. It’s a hassle-free exchange service that takes care of your empty cylinders. Just sign up below and you’ll always have 100% renewable gas when you need it.
Your cylinder can be exchanged in our Cylinder Loop if it’s a standard 14.5 Oz / 60L gas cylinder approved for use with sparkling water makers.
Your cylinder can’t be exchanged in our Cylinder Loop if it’s damaged. Also, we do not accept the Soda Stream Quick Connect cylinders with the pink ring.
1. Order and get your gas cylinders.
2. Enjoy your carbonated water.
3. When the cylinders are empty, put them in the return box and hand it to a USPS carrier.
4. A new order will automatically be placed. No need to log in.
5. FedEx will deliver new gas cylinders to you.
Aarke CO2 gas is exclusively produced from renewable resources within the agricultural industry. This means that the CO2 comes from sources already in the eco-system – we’re not adding any unnecessary CO2 gas to the atmosphere.
Yes, The Cylinder Loop is an on-demand subscription service. This means that after you sign up for the service and place your first order, we securely save your payment details. This way, you won’t have to place any additional orders on our website when you want to exchange your empty cylinders.
The difference from a traditional subscription model is that you (and only you) control how often your cylinders are exchanged. You will only get charged after you send us the empty cylinders – and the full cylinders are on their way to you. Only you decide when this happens depending on your sparkling water consumption.
There is no specific timing for a cylinder exchange in The Cylinder Loop. It depends entirely on how often you carbonate and drink sparkling water.
In The Cylinder Loop, 2 empty cylinders can be exchanged at a time with our exchange box. We recommend having 3 cylinders in total at home, so you can still have one in your Carbonator, while you're waiting for the other two to be exchanged.
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.
There’s no need to manually place an exchange order on our website. The Cylinder Loop exchange works like this:
1. Once you have two empty cylinders, you screw the valve caps the cylinders came with back on – and put the cylinders back in the box they arrived in (the exchange box).
2. On the back of the box, place the included shipping sticker over the existing shipping label. Then put the box with your two empty cylinders in your mailbox or give it to a USPS carrier.
3. Once we receive a confirmation that you have posted empty cylinders, we will automatically charge you $42.00 for the 2 full exchange cylinders and send you a tracking number for them. That’s it! The full gas cylinders will be delivered to you with FedEx fast shipping.
Usually, yes. But it depends on the condition and model of your gas cylinder. We accept standard 400-425g (14.5 oz) /60L gas cylinders approved for use with sparkling water makers.
We do not accept cylinders that are damaged. We do not accept the Soda Stream Quick Connect cylinders with the pink ring.
In all other cases, yes – you can exchange your empty cylinder from another brand to get started with The Cylinder Loop.
For The Cylinder Loop, FedEx will send out the full cylinders to you, while USPS sends the empty ones to us.
Please note that if you order the Carbonator together with the start exchange box and CO2 cylinders, the parcels might arrive at different times due to the packages being sent from different locations.
Since the cylinders classify as hazardous goods, they must be shipped with ground transportation which effects the delivery time. Once USPS confirms to us that they have your exchange cylinders, we initiate your cylinder order. The delivery time will then be 2-5 days. When this new order is on its way, you will receive an e-mail and a tracking link.

Yes. You will be asked to create an account at checkout to proceed with your order. This is required to enable us to securely store your payment method and automatically charge it when you decide to exchange your cylinders in the future.
It’s easy. Just stop giving the exchange box with empty cylinders to USPS and you will never be charged for an exchange again.
If you no longer want us to store your payment information, contact info@aarke-usa.com and we will delete your data from our system. If you are a registered user, your account, purchase history and quick checkout address information will also be deleted, since they are connected.
