Replacing CO2 Cartridges

Your Sodastream will come with a full CO2 cartridge, which will carbonate about 60 liters of soda. In our house, that's about 2 months worth of soda.

When it needs replacing, you can do so by mail through the Sodastream website, or you can find a retailer near you that carries the cartridges, take your empty cartridge in, and get a replacement cartridge. The cost is around $15.

It's a good idea to buy a spare to have in the house for when you run out!
