Every CO2 supplier we could find in the Charlotte area (North Carolina) was checked one by one, and 18 of them made the list. Every one of them exchanges rather than refills, so you hand over your tank and get a different one back. Worth knowing before you drive. 5 would not confirm either way, so those are marked call to confirm rather than guessed at. 4 confirm food grade CO2 for anything you actually drink; the common sizes here are 60L, 5lb; most cover welding, soda, homebrew.

Official current branch page confirms the active Charlotte gas and welding store and carbon dioxide availability. A current April 2026 Charlotte discussion specifically identifies the Airgas store near the airport for kegerator CO2 and reports filling a 5 lb tank there. Food-grade status was not explicitly confirmed. Email is corporate/general contact. Same-cylinder refill is not confirmed. The report of a tank being filled here came from a community discussion, and Airgas branches elsewhere consistently exchange rather than refill. Ask before you go if keeping your own tank matters.
