a simple understanding of air pressure will make thigns alot easier


first off just find out which way the wind is blowing....if its blowing in, then the window is a bad option...if not, then ur golden, just blow hits out the window....DO NOT turn the fan on because if u remove air from the room more air will have to fill in to replace it, and it will come in from the window

if the wind is blowing in, just close the window, put a towel on the door and exhale str8 into the exhaust fan with it turned on obviously
