Lots of parents, teachers and students have found themselves recently with a timely project: making homemade air filters for classrooms and school spaces to help protect from the spread of COVID-19.

They’re called Corsi-Rosenthal cubes, and they’re not too complicated to make with some air filters, tape and a big box fan. But one epidemiologist at Arizona State University is taking this a step further.

Megan Jehn is an associate professor of global health at ASU, and she also leads the COVID-19 Community Response Teams there. And over the holiday break, she and her kids decided to construct the cube project on a bigger scale. The Show spoke with her to learn about it.
