How many liters does one cylinder make?

SodaStream rates it at 60 liters of carbonated water. Heavy daily users typically go through one in a few weeks.

Do I need to bring back an empty cylinder?

Yes. This is an exchange cylinder, so the price assumes you return an empty SodaStream cylinder. Without an empty, stores usually charge a separate deposit.

Will it fit my SodaStream machine?

It fits all SodaStream machines, per the listing. It uses the standard SodaStream screw-in connection, not a ball-lock keg fitting.

Is $31.96 a good price?

It is the only new price listed as of November 6, 2026, so there is nothing cheaper to compare it to. Exchange cylinders commonly sell in the low $30s, so it sits in the normal range.

Can I use it with a Drinkmate or other brand?

No. It is made for SodaStream machines. Other brands use their own cylinders and connectors.

Our take on the SodaStream CO2 Cylinder Exchange

This is a 60-liter CO2 cylinder for SodaStream home soda makers, sold as an exchange: you hand in an empty cylinder and get a full one. It fits all SodaStream machines and uses a ball-lock connection. At $31.96 at The Home Depot as of November 6, 2026, it is the only new price listed, so there is no cheaper new option to compare against right now.
