Wake Forest just released a study on best materials and quilters cotton..

was rated very high. Unfortunately, I havent been able to find the full results.

"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.

The inferior performers consisted of single-layer masks or double-layer designs of lower quality, lightweight cotton."
