Every CO2 supplier we could find in the Columbus area (Ohio) was checked one by one, and 15 of them made the list. 5 will refill the cylinder you walk in with. 6 only swap it for a different tank, which matters if yours is new or an odd size. 4 would not confirm either way, so those are marked call to confirm rather than guessed at. 3 confirm food grade CO2 for anything you actually drink; the common sizes here are 5lb, 100lb, 10lb; most cover soda, welding, homebrew.
