So, in a lot of homes, fans usually blow air towards the inside. This makes sense if you’re trying to keep the AC from escaping, right? But what about keeping the air fresh?

The results of this video seem very counterintuitive to me. They seem to suggest the best way is to have a table fan pointing out of a window instead of keeping the pedestal pointed inwards. This is something that no one does (Even the makers advertise its use as inward pointing)
