What does "on-demand" gas cylinder refill service mean?

This means that you you can order a gas cylinder refill at any convenient time and only when you need it, instead of it occurring at a specific time interval like with traditional subscription models. When you place your first gas cylinder refill order, we will securely save your payment details. This way, if you ever want to refill your cylinders with us again, you could log in to our website and place a new gas cylinder refill order in just one quick step.

What types of empty cylinders are compatible with the service and can be refilled here?

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.

I have made a refill order and received my full cylinders. When should I return my empty cylinders to Aarke?

As soon as possible is best. From the receipt date you will have 7 days to send us back your empty cylinders using the same exchange box. If you don’t, we will have to charge you £25 per cylinder for non-return. But don’t worry if you forget: We will send you return reminder to make sure this does not happen.

Why does a charge for non-return apply if I don't send back my empty cylinders to Aarke on time?

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.

Where should I drop off the box with empty cylinders?

Drop off the exchange box with the empty cylinders at your nearest DPD Depot .

How do I know if the gas cylinder is empty and ready to be returned?

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. 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.

How many cylinders can be refilled at a time?

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.

How long does the shipping take for refill orders?

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.

great service for great products!

Easy peasy, water squeezy.

Great product. Still on my first canister. Not sure how many bottles i have carbonated yet but it seems to be going on forever.

Excellent customer service. And yes I’m enjoying the bubbles!!!

Austausch der leeren Zylinder funktioniert hervorragend

Tout parfait !!

It arrived on time, thanks

Helaas was een van de twee cilinders lek, maakte een raar geluid en na een paar keer gebruik al leeg.

Das klappt prima mit der Lieferung und der Zylinder hält erstaunlich lange. Ich bin sehr zufrieden m it Aarke.

Omruilen gaat erg gemakkelijk. Het enige wat beter zou zijn is als ik de nieuwe flessen direct bij een pakketpunt kan laten leveren.

Alles bestens

It works ( most of the time) !!

Juste excellent

Was slow to deliver, updates on delivery status not great

Great

nous buvons beaucoup d'eau pétillante et la cartouche dure longtemps

Love the replacement recycle loop

Great

Top!

Excellent produit. Livraison très pratique.
Cette marque ne mérite que la meilleure note .

Bis jetzt sind wir sehr zufrieden; auch die Anwendung ist gut!

I value that they are sustainably sourced, and that I can send them back for replacement, rather than the cartridges ending up in landfill. That is a huge plus for me and the environment!

Elles sont très fonctionnelles et parfaites. La durée d'utilisation est très satisfaisante.

Alles ist in Ordnung!!!

Delivery and return is very poor

Réception rapide et cartouches de qualité
