I’d guess that a cheaper, wall-mounted version of CleanAirKits/Airfanta would be a better product. It’s just a box with fans and slots for filters, the installation labor is significantly lower, you get better aesthetics, and not everyone has 52 inch ceiling fans at a standardized mounting length already so the market is potentially much larger with a standalone device.
The problem with the ceiling fan is that it’s not designed for static pressure, so its effectiveness at moving air through the filter will depend on contingent factors like the blade area ratio and distance from the ceiling (which determines how much filter area you can fit). 180 CFM @ 33 dB is better than the Coway but only matches a single box with ~7 PC fans on medium; you can do better with a custom designed ceiling fan but at that point the fan needs to be part of the product.
