How it works
Home CO₂ refills, made simple
Order online, GLS brings full cylinders, your empties go back and get refilled in Spain. Here's the full journey.
Secure paymentDelivery & return shipping includedNo deposit on subscriptionsRefilled locally in Spain
Order online
Choose one-time or subscription and pay securely — a one-time order ships for the earliest available date, and you pick when a subscription starts. Your invoice arrives by email right after payment.
GLS delivers your cylinders
To your door or a nearby GLS ParcelShop. You'll see the carrier's expected delivery date and get email updates: shipped, out for delivery, delivered.
Return your empties — free
Hand them to the courier with your next subscription delivery, or drop them at any GLS ParcelShop with the prepaid label or QR code we email you.
We refill and reuse
Every returned cylinder is inspected, sanitised and refilled in Spain with food-grade CO₂ — ready for its next round of bubbles.
Returns and deposit, without the small print
Subscribers pay no deposit at all — they simply hand their empties to the courier at their next delivery, or return them within 7 days of it. If they cancel or pause, the empties are due within 7 days.
One-time orders carry a €12 deposit per cylinder, returned as EcoFizz account credit as soon as your empty reaches us. Stopping for good? Ask us and we'll refund it instead.
Return shipping is always free and always included in the price — via any GLS ParcelShop or, on a subscription, by handing empties to the courier.

Subscribers just return empties at their next delivery — the €12 deposit only applies to one-time orders.
All-inclusive price
VAT, delivery and the return shipping of your empties — always included, no hidden costs.
Refilled in Spain
Cylinders are refilled in La Roca del Vallès, near Barcelona, and your empties can go back with the same courier.
