Can I use Mitte Home without the CO₂ cylinder for still water?

No, Mitte Home requires a CO₂ Cylinder to be installed at all times for our proprietary priming to be possible. We recommend Mitte Home Cylinders, available in our online store or through Smart Refills. Other CO₂ cylinders can be used with Mitte Home also. Full details of supported cylinders can be found in this article: What CO₂ cylinders does Mitte Home support?.
