I admit I do not have much knowledge on this front, so I would like to ask knowledge here from others for best options to reduce. While I know there is no perfect solution truly, what could be a good resource for reducing?

I don't think that would work well. I did a crude thing with a single furnace filter instead of 4 of them and that worked ok though.

    May have to try and dig out his video. It absolutely worked, but may have been more of a dust filter.

    It might be useful as a desperate improvisation but otherwise get a real filter. You want to filter out very fine particles. AQI is measured at 2.5 micron but you want sub micron filtering if you can get it.
