We highly recommend that you use the 60L 400-425g CO₂ Mitte Home Cylinders provided by Mitte for your Mitte Home. You can sign up for Smart Refills to make sure you never run out.
It is also possible to use 60L 400-425g CO₂ cylinders with a universal valve but, in this case, proper functionality cannot be guaranteed.
Please take into account that the force needed to insert cylinders other than those from Mitte is higher. You will have to turn the cylinder a little further than the Mitte cylinders.
In any case, if you hear some CO₂ leaking after inserting a CO₂ cylinder, please continue screwing in the canister until the “hissing” sound is gone.
If the carbonation levels in your sparkling water seem low, please screw in the CO₂ cylinder a bit further.
