air a room

[Itasan]

'air a room' = to let fresh air into a room
Is this (air a room) BrE? If so, what is the
American equivalent?
'air out a room'?
Thank you.

well yes "air out a room" makes sense and is what we would say. usually if there is a reason the room needs air (it smells, its smokey), conversationally, you usually wouldn't say "air out the room", you'd just say "open some windows" or whatever needs to be done. it wouldn't be wrong though. "air the room" doesn't sound right, we don't use that expression.
