[local] gourmet air tasting

Nitrogen makes up almost 80% of the atmosphere, with oxygen taking 20% and everything else totalling to a couple of a percent.   The nitrogen is mostly inert, so you can replace it with another mostly inert gas, say, helium.

If you then filled a large enclosed space up with this mix, say, a sealed mattress bag, you could sit in there and breathe

You always have such interesting ideas! Do you have both oxygen and helium tanks? Or did you use something like scuba air depressurized?

A friend ordered my custom atmosphere for me at a scuba shop. It came in one tank. I have some amusing videos from the experience, which I will post soon.
