Quick answers
Everything,
before you swap.
Keep the machine you own. We swap any major 60L cylinder, fill it to 450g, deliver it to your door, and collect the empty. Here's how the loop works, what fits, and what it costs.
Will it fit my machine?+
Yes for the standard screw-in fitting. We swap cylinders that work with SodaStream, Aarke, Philips and Breville, plus any standard 60L cylinder. Newer SodaStream quick-connect models use a different cylinder. Check your model and we'll point you the right way.
Do I need to buy an OH Bubbles machine?+
No. The refill loop works with the machine you already own. If you don't have one yet, our AllFizz, EVOSS and SPRKL soda makers run on the same cylinders. Browse machines →
What can I make sparkling?+
It depends on the machine. AllFizz is built to make water and other drinks sparkling. EVOSS and SPRKL are for water only. Whatever the machine, the gas is the same food-grade CO2, filled locally.
How does the swap work?+
Order online and full cylinders arrive at your door, refilled locally to 450g. Your empties go back in the same box with a prepaid label inside. Leave it for the courier. No trip, no queue.
Why 450g?+
We fill to 450g, around 10% more than the 400 to 425g norm. More gas in every cylinder means fewer swaps across the year and one less errand.
What if I'm not home for delivery?+
Leave your cylinder in a safe spot. We deliver and collect from your doorstep, so you don't need to be in.
How do I send the empties back?+
Reuse the box your full cylinders arrived in. The prepaid return label is inside. Drop it with the courier and the return is free.
What does a refill cost?+
A one-off refill is $29 per cylinder, with a two-cylinder minimum. First-time orders add a $10 refundable deposit per cylinder, returned when you stop swapping. Free return courier is included. Order refills →
When do I pay?+
You pay when you order. There's nothing to settle on collection. The free return courier brings your empties back to us.
Is there a subscription plan?+
Yes. Annual plans deliver cylinders on a set cadence at the best price per cylinder. Plan pricing is being finalised. See plans →
How is the $10 deposit handled?+
It's a refundable credit on the cylinder itself, not a fee. You pay it once per cylinder, and when your empty returns the $10 goes back to your account to reuse on your next swap.
Why not just buy a cheap kit online?+
CO2 is a pressurised gas. The cheap route usually means unverified food grade, uncertified cylinders or adapters, and you doing the refilling. We fill, test and certify locally, then deliver and collect. Safe, and you never think about it.
Is the CO2 food grade?+
Always. Every cylinder is filled with food-grade CO2, refilled locally in a certified pressure vessel that we test on each fill.
What are the syrups made from?+
Real fruit pulp, made in Italy. Low sugar and low calorie, with no corn syrup, GMO or artificial flavours. Built for sparkling water, cocktails and mocktails. Shop syrups →
