It didn't really come out of academia in that way. It was an innovation borne out of necessity during Covid. I don't think I've seen anybody using a box design for it. If you have a source, I'll be happy to be corrected.

Regardless technology is often named after people who made it popular, especially when original inventors are unknown or too diffuse.

not that much of innovation.

i build one like this back in 2018 during california fires. used it mostly in garage for filtering air when i work on "things". decommissioned it last week.

i guess i am not the only one who came up with this idea prior to covid as this is pretty obvious

They're the ones who did the actual testing/measurements. I had a box fan attached to a single filter (for wildfire smoke) but was unaware of how inefficient it was.

i did think the 4-sided design using the cardboard box as a base was very efficient. one of the contributions here was Corsi and Rosenthal did this in a lab and reported particulate counts, flow rates, and energy usage. So there was some kind of intellectual contribution to broaden adoption by giving it more of an imprimatur of quality

other refinements were using a shroud to prevent back flow

You should tell us your name and publish the result so we can credit you for the work. Would love to call it whatever your name is instead.
