Thanks for writing this! I referenced this in a shortform about how commercial air purifiers can be improved upon.
I’m curious how the fan has enough pressure to get the measured airflow. I would think that ceiling fans are extremely unoptimized for pressure, but maybe they move so much air that 180 CFM is a small fraction of their max airflow?
Since writing this I’ve learned more about how the air flows around ceiling fans, and I expect that (a) using slightly taller filters that extend below the blades and (b) adding a cowl would help a lot.

My guess is it’s just that the fan is really big?
