Seattle · Washington
Every CO2 supplier we could find in the Seattle area (Washington) was checked one by one, and 22 of them made the list. 3 will refill the cylinder you walk in with. 10 only swap it for a different tank, which matters if yours is new or an odd size. 9 would not confirm either way, so those are marked call to confirm rather than guessed at. 8 confirm food grade CO2 for anything you actually drink; the common sizes here are 60L, screw-in and quick connect, soda canisters; most cover soda, welding, homebrew.

Seattle, WA · delivery / mail-in, no walk-in counter
Hours Order online; most morning and early-afternoon orders delivered same day, otherwise next day
Doorstep delivery service, not a walk-in counter. Leave your empty canisters outside and they are collected when the full ones are dropped off, so you get a different filled canister rather than your own back. Delivers within Seattle city limits, free to most zip codes and $5 otherwise. Pickup can be arranged in North Seattle near the Northgate exit off I-5, which they say customers from Bellevue, Issaquah, Tukwila, Renton and Lynnwood use. Handles both screw-in and quick connect soda canisters, which fit most machine brands including SodaStream, Drinkmate, Aarke, Ninja and Breville. Unusually, they accept expired canisters as long as the cylinder is visually sound, which most suppliers will not do. The owner confirmed in October 2026 that the CO2 is beverage grade, which for drinking purposes is the same standard as food grade.
