How cylinders work with Soda Club
Cylinders are owned by Congas. When you finish one, return it and we'll send a new one free of charge, managed from your account. If more than 12 months pass without returning a cylinder, a charge of €12 per unit applies.
The calculation you've never done
The machine pays for itself
Sparkling water from the supermarket costs between €0.53 and €0.80 per liter. With Congas, you can carbonate at home from €0.275 per liter.
A cylinder yields up to 60 L and lasts about a month. You order, they arrive at your home, and you exchange the empties with the delivery driver.
€186–378
in savings per year compared to buying bottles
You recoup the machine in the first few months. From then on, you save every time you turn on the tap.

Soda Club · Leasing and Exchange
Why our prices are possible
The prices you see up to €0.28/L are only possible thanks to the Soda Club's circular leasing and exchange system. The cylinders are from Congas: you use them, return them empty when your next order arrives, and Congas refills and recirculates them. No cylinder purchase, no new manufacturing, no waste.
01
Congas delivers full cylinders to you
In 24–48 hours at your home. You don't buy the cylinder, you lease it.
02
Make sparkling water at home whenever you want
No going out, no lines. The cylinder is yours until it's empty.
03
You return the empty ones to the messenger
At the same time you receive the full ones. No deposit, no extra management.
04
Congas recharges them and the cycle repeats
Zero waste, minimal production costs. Hence the price of €0.28/L.

Frequently asked questions
Most frequently asked questions
Are they compatible with my SodaStream?
It depends on the model. Models with a standard screw-in connection (Jet, Genesis, Cool, Source, Spirit, Fizzi, Crystal, Penguin, Revolution...) are compatible.
Terra, Art, Duo, E-Duo, Gaia, and Enso models use the SodaStream Quick Connect system and are not compatible with our cylinders. Use the compatibility finder to confirm.
When will my order arrive?
Orders placed before 12:00 (Monday to Friday) are dispatched the same day. Delivery within 24–48 hours throughout mainland Spain. You will receive an email with tracking information.
Do I have to pay a deposit for the cylinders?
No. The delivery driver delivers the full cylinders and collects the empty ones at the same time, at no additional cost. There is no deposit or extra paperwork.
How much sparkling water does each cylinder make?
Each 60 L cylinder carbonates approximately 60 liters of water at a medium carbonation level. With 4 glasses a day, it lasts about 2 months.
Can I use my SodaStream bottles with your cylinders?
Yes. We only change the CO₂ cylinder. The bottles, the machine, and the rest of the accessories are exactly the same as what you already have.
Stop carrying bottles. Forever.
At-home refills, unbelievably low prices, no contracts.
