Taher Saif, Professor of Mechanical Science and Engineering, and students Onur Aydin and Bashar Emon are testing common household fabrics to better inform those making homemade masks to help stop the spread of COVID-19. “The droplets released during coughing and sneezing come in various sizes and velocities. The fabric for any mask should be breathable and impermeable to high- and low-velocity droplets,” said Saif.
The study found that breathable materials, such as t-shirt fabric, are good options for homemade masks. Find out more and watch videos of the tests.
