Exchanged and refill CO2 cylinder. Designed specifically for your sparkling water maker.
They fit your machine perfectly, ensuring better carbonation and maximum cylinder efficiency. Refill with high-quality, dietary-grade CO2 as used in all traditional carbonated drinks and sodas. Perfect condition – every time you exchange your empty cylinder it undergoes a Triple Quality Control process during which it's inspected, sterilized, and filled with fresh CO2.Safety – every one of your cylinders is made of the highest-grade brass and aluminum. Of over 70M cylinders produced, no cylinder has ever failed. Now, that's something to feel safe about! Your carbonating cylinder will, on average, make up to 60L of sparkling water. However, how frequently you need to replace your carbonating cylinder will vary according to the level of carbonation you use. Generally, a cylinder will last you anywhere from 4 to 8 weeks. Backup cylinders are there so you always have a full one at home and can quickly swap out as soon as your current one runs out of gas. We recommend having at least one back up cylinder on hand at all times.
