I was asking because I already have a microwave blower motor. My microwave died a while ago and I pulled it out before throwing the rest of it away, so no cost. I know this is unscientific, but it feels like it could be pulling more CFMs than a box fan. It’s small, but really powerful.

I actually built this setup but I feel like it isn’t doing anything. I have maybe about 8 inches of gap between the top of the filter and the ceiling so that the outlet air flow isn’t obstructed, but it probably doesn’t do too much in terms of actually circulating the air.

The plan was to see if I could build a better filter with the small blower motor before just buying an overhead air filtration system.
