"PROVIDENCE, R.I. [Brown University] — 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.
“The findings show that an inexpensive, easy-to-construct air filter can
protect against illness caused not only by viruses but also by chemical
pollutants,” Braun said. “This type of highly-accessible public health
intervention can empower community groups to take steps to improve their air
quality and therefore, their health.”
Corsi-Rosenthal boxes, or cubes, can be constructed from materials found at
hardware stores: four MERV-13 filters, duct tape, a 20-inch box fan and a
cardboard box. As part of a school-wide project, boxes were assembled by
students and campus community members and installed in the School of Public
Health as well as other buildings on the Brown University campus.
To assess the cubes’ efficacy at removing chemicals from the air, Braun and his
team compared a room’s concentrations of semi-volatile organic compounds before
and during the box’s operation."
