I do think expanding the ceiling fan air purifier would work well. You could make a frame that takes furnace filters, and purify a lot of air very efficiently and relatively cheaply.
If I were doing this again I would extend the filters down below the plane of the fan, now that I know more about how the Bernoulli principle applies.
If you wanted to take this idea to an absurd level, you could install a dropped ceiling made partially of furnace filters, and a grid of fans above it. Maybe have the outer perimeter of fans blowing up and the inner area blowing down, to try to get one large convection through the entire room.
How do you figure out the optimal filter thickness? If you hypothetically had a very weak fan then it wouldn’t push much air through even furnace filters. If you had a magic constant air flow source then you would want the thickest filter possible.
I guess I am just wondering if you could use something better-looking and cheaper, like semi-transparent paper with lights behind it or a washable sheet/tapestry.

There’s probably a way to do this with physics, but I do a lot with trial and error ;)
How do you measure results?
Put particles in the air and measure how quickly they’re depleted. ex: Evaluating a Corsi-Rosenthal Filter Cube
