Most of us have an old T-shirt we’re able to cut up right into a no-sew mask. It’s one of the most convenient fabrics to work with, but there’s lots of variability in how well T-shirt material performs in diagnostic tests. At the Virginia Tech, a single layer of a well-used cotton T-shirt captured 20 % of particles into 0.3 microns. It captured 50 % of particles as a result of 1 micron. A 2013 University of Cambridge study tested two layers of T-shirt which captured about 70 percent of particles down to 1 micron.
Even the 3M surgical mask performed better with stockings in their study: Testing established that it went from blocking out 75% of small particles to 90% by having a pantyhose overlayer. By comparison, an N95 respirator, which can be built to create a tight seal across the face, blocks out at least 95% of small particles when worn properly.
