If all you need is that one lungful, consider a small portable tankless compressor ($15 at your nearest auto-supply) and a refillable aerosol can.

Do they make those? I could fill it from a bicycle pump.

They sure do. Not much use for high volumes or high pressures, but portable and not overly expensive. The one linked is about US$18 or so. You will note that the one linked also states that it is NOT to be used as a duster. Further research will tell you that this is because there is a tendency to vastly over-pressurize if used for this purpose. Go up in price, and you can get one rated for air only.
