Join our qarbo*gas Exchange Program and save!

Enjoy endless gas for your qarbo Sparkling water maker (or any compatible sparkling water maker), with our home gas exchange service.

This is a rental service - with no upfront fee for the cylinders. You only pay for the CO2.

What's the worst thing about running out of gas? Having to lug yourself down to the supermarket to get a fresh cylinder. Save yourself the hassle.

MOST POPULAR - Order 4 or more cylinder exchanges for great savings over traditional cylinder exchanges in the supermarket.

If you're interested in owning the cylinders, you can order them here and then exchange them as normal.

Note: We're currently delivering to Melbourne, Brisbane and Sydney. Please use the Postcode Checker to determine if we service your area. If you'd like to be notified when we're able to deliver to your postcode, click here.

Gas cylinders are delivered by courier (not Auspost). Usual delivery times are 1-2 business days.
