What Are The Best Materials for Making DIY Masks? - Smart Air Filters
Ripped apart a white tee this afternoon and wore a mask out while grocery shopping. Took no more than 5 minutes, using a pair of scissors to cut a strip of white tee that was about a foot and a half long and half a foot wide.

Bottom line: Test data shows that the best choices for DIY masks are cotton t-shirts, pillowcases, or other cotton materials.
These materials filter out approximately 50% of 0.2 micron particles, similar in size to the coronavirus. They are also as easy to breathe through as surgical masks, which makes them more comfortable enough to wear for several hours.
Doubling the layers of material for your DIY mask gives a very small increase in filtration effectiveness, but makes the mask much more difficult to breathe through.
