I see people post this all the time, but I really don't think an axial fan can pull air through a HEPA-like filter. You need to spend $150 on a real solution. It's really not much, includes the filters, and looks a hell of a lot better to boot.

This Old House has a really good breakdown on filtration and air volume and have a pretty clever DIY box fan approach using multiple filters. Still costs under $100. The Wirecutter recommended Coway filter is $185 on Amazon. https://youtu.be/aw7fUMhNov8 https://youtu.be/aw7fUMhNov8

Plus mine has a sensor too, so the fan is only loud when it needs to be.
