Matthias Wandel's secondary YouTube channel has a lot of recent videos about retail air purifiers compared to homemade ones using box fans. I'm not up to snuff on the science of it all, but he does a lot of cool comparisons on the effectiveness of each. Worth a look if you're interested in this sort of thing. https://www.youtube.com/channel/UC3_AWXcf2K3l9ILVuQe-XwQ/vid...

I like his channel. He is one of the few people you will see out there with almost an entire shop full of very useful, but completely diy woodworking tools.

It depends on the purpose, but air purifier should be at the floor because dusts finally fall at the bottom, isn't it?

Earlier quoted context omitted.

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.
