A YouTuber, Joel Creates, recently developed a filter that can be assembled from furnace filters, 3D printed parts, O-rings and PC fans: https://youtu.be/GpA7-EJpKWU
If you want to DIY these there's a FOSS (GPLv3) parametric builder web app that will output files for 3D printing, lasercutting, or handcut foamcore and calculate the performance of different configurations for you:
I built something similar to the boxfan and 4 air filters when I'm doing woodworking, especially sanding. They work pretty well for that if you are on a budget.

About the same as a Coway
But furnace filters are a lot cheapee than most replacement air purifier filters, and that's before you buy your furnace filters at Costco or surplus.
But repairable, cheaper to operate (power and consumables), and quieter for the CADR than Coway.

Files can be purchased by backing the Kickstarter but they won't be sent until November: https://www.kickstarter.com/projects/joelcreates/oddcube-air...
I think this could be substantially cheaper than a build based on a PC case.

There's no real performance difference between DIY and metal PC fan filter boxes, just durability.

This would be a neat thing for case makers like coolermaster or corsair to do a one-off of while the self build market is slumped.
