If you have never acquired a CO₂ cartridge beforehand or are not available at home, you have to buy a new cylinder. In this variant you pay the carbon dioxide (including aroma) and the aluminum cylinder itself. You can then keep it.

Another option is if you want to buy further reserve cylinder. Since you can keep them, this variant is ideal for keeping it in stock for later, thirsty times.

However, you should already have empty CO₂ cylinders at home: all the better! Then you can exchange our cylinder. This can also be understood as "filling a CO₂ bottle or CO₂ bottle". The process is very simple. Order the cheaper exchange cylinders in our shop and receive your cartridges a few days later. Take the full cylinders out of the shipping box and put your empty carbonated bottles in it. Then only stick the free return label back to us, send back to us and you're done! So you can exchange your CO₂ bottles.

In this way, you almost only order the carbonic acid filling because you have sent us back an equivalent CO₂ cylinder. We can only guarantee the low price of the exchange cylinders, since the aluminum cylinders themselves also have a material value. (By the way, a deposit does not fall for CO₂ cylinders on the German market.) Incidentally, we are the only provider to accept cartridges from third-party providers for the return. This does not only affect screw cylinders from Sodapop, Sodastream or others, but also exclusive and expressly also empty Quick Connect cylinder (the cartridges with the pink ring for clicking) from Sodastream. You can find more on the subject of return FAQ).

Important here: take into account how many cylinders you have empty at home. If, for example, 2 cylinders have already been emptied, you can only order 2 exchange cylinders. All other CO₂ bottles in your shopping cart would then have to become a purchase cylinder. As a donkey bridge you can remember: if I want to "fill" my CO₂ bottle or "have" refilled ", I also have to have a bottle that can be filled.
