UConn’s Homemade Air Purifiers that Trap COVID-19, Make Cleaner Air Given to Classrooms

FARMINGTON, Conn. — A group of students from the University of Connecticut along with team members at UConn Health in Farmington built an air purifier out of furnace filters, a fan and tape.

It’s called the Corsi-Rosenthal box, and it traps the COVID-19 virus inside.

“It captures fine particular matter in the air about as fine as a commercial filter,” said Marina Creed, APRN of UConn Health’s MS Center.

It also captures dust, mold, pollen and, of course, viruses.

“We’ve found these are incredibly effective at lowering the levels of particles and these particles transmit infectious diseases like COVID and the flu in classrooms,” said Dr. Kristina Wagstrom from the UConn School of Engineering.
