Students unite to take a hands-on, DIY approach to improving air quality

PROVIDENCE, R.I. [Brown University] — Sure, free local pizza can be great — but what truly draws most Brown students to campus events is the opportunity to create, innovate, and solve problems.

On a sunny Friday afternoon in late November, it was MERV 13 air filters that turned out a crowd at Alumnae Hall.

The School of Public Health lured students to a DIY building session with the promise of learning how to use four MERV 13 filters, plus a box fan, to quickly and easily assemble an inexpensive device powerful enough to filter out particles carrying the SARS-CoV-2 virus.

The air cleaner, called a Corsi-Rosenthal cube in honor of its inventors, is currently in use in classrooms and conference rooms in the School of Public Health as an additional measure to support interventions Brown put in place early in the COVID-19 pandemic to ensure optimal HVAC and filtration system operations.
