I expect Blacknet to add to this but I was taught to sniff the air and taste the air. (I was taught this in Mexico....Amazing that )
When you sniff you are checking for anything that smells of oils or car exhaust.
Hopefully there is no taste to the air but i was told to check for metallic tastes, oily tastes, and to feel for numbness or tingling on the lips or tongues.
You can also ask to see the certificates of the air fill station or ask to see the compressor. There is a certain level of certification required but I don't know what it is.
Hope this helps.....
