I did this for a cheap dust filter when demoing a ~7 cu ft concrete shower pan in my house. Pretty incredible how much material it pulled out of the air; I ended up running through 3-4 filters total throughout the whole process.

I prefer to mount a high-power fan in the bathroom window for demolition.

This bathroom had no window unfortunately, so that was the best solution I could come up without venting it elsewhere in the house.
