If you’re buying a box fan for this project, Lasko makes one that’s designed to have a filter. No DIY needed.

a piece of cardboard on the front to create a circle will help keep airflow consistently in the forward direction

i did a project on these “DIY air filters” this past semester! they actually work very well! i saw a significant reduction of PM2.5 and NOx gasses in my bedroom after having installed it. very good and easy alternative for expensive air purifiers

this just kinda made me realize how tiny and probably useless/inefficient the ones you buy at the store are

I have several fancy air filters but built one of these (but the 3 filter, square version) last summer into my basement while I was sorting through a bunch of old boxes and DANG was it soooo efficient in getting a wild amount of dust out of the way. Those filters were black & caked with dust in less than a week and it was an excellent reminder of just how efficient they are. Absolutely worth the few mins of effort!

The nice thing about this is that you don’t have to worry about silly things like a discontinued replacement filter

I built a similar one but since we always have extra filters, we used four and the fan points up. and, we based it on an actual pre built air purifier we had so we knew it worked
