Air cannot get into the system. If there were a place for air to get in there would be water leaking out from that place. It would be possible to suck in air from the pump side but this post is referring to the city water connection.
Yes, I have experienced this phenomenon. I can fill my coffee pot with what appears to be white water. In about a minute it will clear up. What causes it is a mystery but there is no air getting in. It seems to be the worst right after de-winterizing. Eventually the situation goes away.
