How to Choose a Water Carbonator
How much CO2 is included
The biggest ongoing cost is CO2. Bundles with several cylinders, like the SodaStream TERRA CO2 Bundle and Drinkmate Ultimate Bundle, include three 60L cylinders.
Starter kits usually include one cylinder, and some machine-only listings, like the Philips ADD4902 and Aarke, include none.
Quick Connect or screw-in
SodaStream uses Quick Connect cylinders that click in with one push. Drinkmate, Philips and Aarke use standard screw-in cylinders.
Both types can be exchanged at many retailers. Make sure your machine matches the cylinders you can find locally.
Water only or any drink
Most carbonators should only fizz plain water. Add flavor afterward.
Drinkmate’s Fizz Infuser lets you carbonate juice, tea, wine and cocktails directly.
Safety features
Pressure relief valves release excess pressure automatically. The Philips GoZero Lite also buzzes when the water is ready.
Always fill bottles only to the marked line and use bottles made for your machine.
Bottles
Extra bottles let you carbonate in batches. The Drinkmate Ultimate Bundle includes 1L and 0.5L bottles.
Bottles usually carry an expiration date; replace them when it passes.
Build and budget
Plastic machines from SodaStream, Drinkmate and Philips cost under $200. Stainless steel Aarke costs more but feels premium.
If you already own a screw-in cylinder, a machine-only listing saves money.
