Researchers find air filtration systems provide an added layer of protection in classrooms

With many students heading back to school soon, researchers are gathering information that can help schools set COVID protocols.

Some devices being studied are portable air purification units, which could add a layer of protection and slow the spread of aerosols and droplets in a classroom setting. In fact, New York City plans to have such devices in its classrooms.

“Good Morning America” got an exclusive look at testing by the Mayo Clinic and the University of Minnesota at the Well Living Lab to examine these devices.
