Simple pricing, bubbles included

EcoFizz is a local CO₂ cylinder refill and exchange service for home sparkling water makers (like SodaStream). We don't sell machines — we help people who already own one keep the bubbles flowing: we deliver refilled cylinders, collect your empties and refill them locally in Spain.

EcoFizz cylinders work with sparkling water makers that use standard threaded (rosca) cylinders — including many SodaStream, Aarke, Philips and Brita models. Quick Connect-only machines are not compatible. Use our compatibility checker to confirm your model.

Standard threaded cylinders compatible with our system, whatever the original brand (Philips, SodaStream, etc.), as long as they're in good, reusable condition. The one exception is SodaStream Quick Connect cylinders — that connector is exclusively patented by SodaStream, so we can't refill or accept them.

We don't offer à la carte refills. We work with one-time orders and subscriptions: we send you already-filled cylinders in pairs, and you return the same number of empties separately.

Everything: the refilled CO₂ cylinder, VAT, delivery by GLS and the return shipping for your empties. There are no extra shipping fees, no minimum order and no hidden costs at checkout — 17 € per cylinder for one-time orders or 16 € per delivery on subscription is the final price.

Whenever you've paid a deposit for a cylinder — the €12 added on a one-time order, or the €12 charged when a subscription empty isn't returned in time — returning the empty gets you €12 back as EcoFizz account credit, applied automatically to your next order before your card is charged.

Credit is added automatically once GLS scans your returned cylinders, usually within a few days. If more than 3 days have passed since GLS confirmed receipt and you still don't see it, contact us and we'll look into it right away.

Subscribers who return their empties within 30 days of each delivery never pay a deposit at all.

You have 30 calendar days from receiving your new cylinders to return the empties. If a cylinder isn't returned within that window, we automatically charge €12 for it. Return it later and we'll credit €12 per cylinder back to your account, applied automatically to your next order.

Choose home delivery or a GLS ParcelShop near you, and pick your delivery date at checkout. Once your shipment is on its way, you'll see GLS's expected delivery date and receive email updates until it's delivered.

Not at the moment — we currently deliver only within mainland Spain, as shipping to the islands is still too expensive. Write to info@ecofizz.es if you'd like to be notified when that changes.

GLS attempts delivery twice. If there's no answer either time, your package waits at the nearest GLS ParcelShop for up to 10 days. If it isn't collected in time, it comes back to our warehouse and we add its value to your account as credit, so you can reorder whenever you're ready.

Three easy ways: hand your empties to the GLS courier when your next subscription delivery arrives, drop them at a GLS ParcelShop with the prepaid label or personal QR code we email you, or request a GLS home pickup. To arrange a drop-off or pickup, open Cylinder returns in your account (web or app) and choose Request GLS return.

Good to know: GLS only accepts cylinders already registered as a return, so always request the return first. And for drop-offs use a staffed ParcelShop — GLS lockers only hand out parcels, they can't take them.

Returns are free and should be made within 30 calendar days of delivery.

Yes. Even before your first order you can request a return of your existing empties, and we'll add the credit to your account to use toward your first purchase.

You pay shortly before each delivery, never months in advance. We email you a reminder about a week before your delivery date, so a charge never takes you by surprise.

Yes, anytime and with no minimum commitment — from the web or the app. If a delivery you've already paid for is on its way, it still arrives (that charge isn't refunded), and future charges stop immediately.

From the sign-in screen on the web or in the app, enter your email and tap “Forgot your password?”. We'll email you a 6-digit code — enter it together with your new password (minimum 6 characters) to finish.

Write to info@ecofizz.es with the code you're trying to use. Occasionally a code needs to be activated manually on our end, and we'll get it working for you right away.
