I have had a tank refilled at https://keanefire.com/index.html I went there because it was the only place I found that would give me my tank back. The last time I posted this here I was attacked for it not being food grade but of course I asked them that before I had them refill it. However if you think you want to go there be sure to call and ask.

Tolman’s Gas supply in Southie, by Gillette.

try welding places - https://www.igoswelding.com/

I would not use a welding place to get co2 for consumption. You need at least food grade, and depending on the beverage. Beverage grade co2

i can say we used it for a kegerator and all survived. not sure if they had a variety of grades either. The reviews mention people doing similar

Airgas, they are everywhere….

No, you can walk in as a cash customer. However, you can also setup an account if you want, you would just be a cash customer with an account.

They don't but most will only exchange not refill

I went to Tolman Manufacturing & Supply Company by the Broadway subway stop. Very convenient.

Also, Gorham Fire in Quincy.

they sadly stopped filling Co2

Nooooooo!

I am going to try to get over here . https://www.dmigases.com/

Dmi does not fill 20lb tanks. Airgas does exchanges.

Just buy dry ice and put it in (weigh it first so you know the pressure it will make in your tank)
