University of Arkansas researcher and physics professor Hugh Churchill is creating and testing portable air filters that help remove infectious airborne particles — including respiratory droplets that carry coronavirus — from interior environments using simple, inexpensive supplies available at any general department or home improvement store.

And he wants to teach you how to make your own. Duct tape, a basic box fan and commercially available air filters are all you’ll need.

“While masks and vaccines are polarizing topics, there shouldn’t be anything controversial about clean air,” Churchill said in a UA news release. “These devices facilitate that. They provide an additional layer of protection that could be widely deployed to make our K-12 and university indoor spaces healthier during this wave of the pandemic. And they’re easy and inexpensive to build. My 9-year-old built one.”
