I’m trying to circulate air in my house. We have a split level home (lower, middle, upper, in a zig zag sort or arrangement. I hate it, but that’s beside the point) and the lowest level is always too cold and highest level too warm. I want to move air from the lower level to at least the middle level.

I need a fan, preferably small or thin profile that blows 90° from intake. Ideally a box fan that has a horizontal intake but exhausts up or sideways. What I’ve done in previous years is have a rotated fan that pointed up, intake from below, and was raised off the ground.

The closest I’ve found is a carpet dryer drum style. It has round intakes on the side and a rectangular vent on the front. That would totally work (point the intake at the cold room and the exhaust up towards the middle room) but it’s way over powered for my situation. Also, it’s a bit wider than ideal, though slimmer than what I used last year.
