Try boiling water in a vessel.Even before the water starts boiling, bubbles appear on the inner side. These are air bubbles illustrating that water has air dissolved in it.

The quickest way is to heat it up. You'd want a thermometer to help validate that gases are leaving the water and it isn't boiling (just check that the temperature is below 100oC), but if you see bubbles at those lower temperatures, it's air.
