Replacing hundreds of cans and plastic bottles with one machine, the Aarke Carbonator Pro is a more sustainable approach to sparkling water. The unique drink maker requires only one hand to operate and delivers fizzy H2O in mere seconds. Place the included glass bottle on the machine's base and pull down the lever until it clicks, then a CO2 cylinder will fill the bottle with bubbles. Its slim silhouette and matte black finish complement most kitchen aesthetics, while its cordless design won't clutter counters. Compatible with 425 g gas cylinders, including Sodastream, sold separately.
