Every CO2 supplier we could find in the Salt Lake City area (Utah) was checked one by one, and 12 of them made the list. 3 will refill the cylinder you walk in with. 1 only swap it for a different tank, which matters if yours is new or an odd size. 8 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 1.5 lb to 75 lb, SodaStream, paintball; most cover soda, welding, homebrew.

Owner confirmed by email (Sep 2026): customer chooses refill or exchange, and tanks are filled on site while you wait. All CO2 is food grade. Fills any size from 1.5 lb up to 75 lb, including paintball tanks and SodaStream cylinders. One of the few places in Salt Lake City that will fill a customer's own tank on the spot.
Official current pages confirm this Salt Lake City fill plant, CO2 supply, food and beverage applications, empty-for-full cylinder exchange, and customer-owned cylinder filling. Exact CO2 cylinder sizes were not published in a branch-specific portable-cylinder format. Email source: https://www.allbiz.com/business/djb-gas-services-inc_1c-801-908-7800.
Official current site explicitly states that State Cylinder performs in-house CO2 cylinder filling and refilling and serves food and beverage, paintball, industrial and welding customers. The site does not explicitly identify the CO2 as food-grade or publish refill sizes. Email is corporate/general contact; Email source: https://statefire.com/.

Official current branch page explicitly lists Carbon Dioxide among gases available. A current local listing includes an October 2025 review specifically praising CO2 exchange. Same-cylinder CO2 refill and food-grade status were not established. Email is corporate/general contact; Email source: https://stores.lindedirect.com/. May not be same day: a local supplier reports customers are often asked to leave a cylinder and return for a different one rather than swapping on the spot. Worth asking before you go.
Current local listings and BBB records verify the Salt Lake City depot. NuCO2's official current site identifies Beverage Grade CO2 and commercial beverage carbonation service. This is primarily commercial installed-system service; portable customer-cylinder refill versus exchange was not established. Email is corporate/general contact; Email source: https://www.nuco2.com/Home/Contact.
Official current branch page verifies this Salt Lake City location. RMA's current CO2 page offers gas and liquid CO2 for pickup or delivery and identifies food and beverage applications; its food and beverage page states it provides food and beverage grade gases. Portable customer-cylinder refill versus exchange and sizes were not established. Email is corporate/general contact; Email source: https://rockymountainair.com/contact/.
Service not confirmed. An earlier claim here came from a 2024 community discussion rather than from Airgas, and a local supplier reports this branch no longer handles walk-in refills or exchanges, focusing on larger accounts. Airgas branches elsewhere generally exchange cylinders rather than refill your own. Call before making the trip.
Official current branch page confirms industrial gas supply at this location. Humphries' current catalog explicitly offers carbon dioxide cylinders, including medical USP CO2, but branch-specific portable customer-cylinder refill versus exchange behavior and food-grade CO2 were not established. Email is corporate/general contact.
Official current Admiral Beverage page verifies M&M Distributing at this Salt Lake City address as an active beverage distributor. A current business directory categorizes this exact location under beverage CO2 tank refill. Because the CO2 service detail is not stated on the official page, refill versus exchange and food-grade status remain unknown. Email source: https://www.utah.gov/pmn/files/1312081.pdf.
Current local listing verifies the Salt Lake City industrial location. Norco's official industrial-gas page states it operates a Salt Lake City fill plant and provides Carbon Dioxide. Portable customer-cylinder refill versus exchange, food grade, and supported sizes were not established. Email source: https://www.norcoindustrial.com/salt-lake-city.

Current local business listings verify the active homebrew store. A 2024 Salt Lake City discussion describes The Beer Nut as a place to exchange a beverage CO2 tank. Same-cylinder refill and food-grade certification were not established from a current authoritative source. Email source: https://homebrewersassociation.org/directory-shopstest1/listing/the-beer-nut-inc/. Turnaround may be long: a local supplier reports empty cylinders are collected weekly by an outside gas company, filled off site and returned, which would mean leaving your tank for up to a week rather than swapping it over the counter. Not confirmed with the shop, so ask about timing before you drop a tank off.
Current business directories identify this Salt Lake City ICEE facility and categorize the location under beverage CO2 tank refill / beverage dispensing equipment. The current corporate site does not expose branch-level CO2 service details, so moat fields remain conservative.
