DIY air filter can effectively filter out viruses, air pollutants: Study

A team of researchers from Brown University's School of Public Health, Brown's School of Engineering and Silent Spring Institute found that simple air filtration devices called Corsi-Rosenthal boxes are effective at reducing indoor air pollutants.

The study, which analyzed the effectiveness of Corsi-Rosenthal boxes installed at the School of Public Health to help prevent the spread of COVID-19, is the first peer-reviewed study of the efficacy of the boxes on indoor pollutants, according to the authors.

Lowering indoor air concentrations of commonly-found chemicals known to pose a risk to human health is a way to improve occupant health, according to lead author Joseph Braun, an associate professor of epidemiology at Brown.
