Air in cold water

in THE MAIN WALL
In the morning while running the cold water for brushing teeth, noticed air spitting out of facuet. I'm on a municipal water system and do not have a backflow preventer in the main line, nor do I have any bladder tanks for pressure control. Any idea where and why I'm getting air in just the cold water? Hot water no problem.

    Cold water holds

    more air in solution than hot water. Heating water releases air (you may get a small puff when opening your hot tap but it is not likely in solution in your water). Your aerator give your cold water a last swirl before you see it. Nothing to be concerned about.
