Testing Shows Type of Cloth Used in Homemade Masks Makes a Difference, Doctors Say
Testing was done by the Manufacturing Development Center at the Wake Forest Institute for Regenerative Medicine, part of Wake Forest Baptist.
What the test team found was that the masks’ effectiveness varied widely. The best homemade masks achieved 79% filtration as compared to surgical masks (62% to 65%) and N95 masks (97%). But other homemade masks tested performed significantly worse, sometimes demonstrating as little as 1% filtration, Segal said.
The best-performing design was constructed of two layers of high-quality, heavyweight “quilter’s cotton” with a thread count of 180 or more, and those with especially tight weave and thicker thread such as batiks. A double-layer mask with a simple cotton outer layer and an inner layer of flannel also performed well, he said.
