The Aarke Carbonator 3 in Sand is a manual sparkling water maker built around a stainless-steel enclosure and a reusable 1L BPA-free PET bottle. It suits households that want freshly carbonated water without an electrical connection: fit a compatible screw-in CO2 cylinder, attach chilled water in the bottle and use the lever to carbonate to taste. Aarke states that one standard cylinder can carbonate up to 60 litres and that the machine has been tested for more than 10,000 carbonation cycles.

Its cordless design keeps placement flexible on a kitchen counter, while the precision nozzle and controlled pressure-release system support a simple, repeatable routine. The supplied PET bottle holds 800ml to its marked filling line and is intended for hand washing rather than the dishwasher. Standard 400–425g / 60L screw-in cylinders are compatible, including SodaStream screw-in cylinders, but SodaStream Quick Connect cylinders are not.

Key Features

Simple Manual Carbonation

Fill the PET bottle to its marked line with cold water, screw it into place and use the lever to carbonate. The machine runs entirely from the pressure in a compatible CO2 cylinder.

Built for Repeated Use

Aarke uses a stainless-steel enclosure around the Carbonator 3 and states that the design has been tested for more than 10,000 carbonation cycles. The reusable PET bottle is food-contact approved and should be hand washed.

How It Compares

Compared with the Carbonator Pro, Carbonator 3 uses a screw-in PET bottle rather than the Pro's Push-to-Lock system and dishwasher-safe glass bottle. Both are manual, electricity-free machines that use standard screw-in CO2 cylinders.
