Here’s the deal, we’re not trying to be prescriptive—we want you to use what is readily at-hand, easy, and available. There may be a few materials that you have lying around that you didn’t know are great to repurpose for masks, and that’s where we come in…
Woven cotton, cotton/polyester blends, silk, flannel, quilter’s cotton, unused mechanic/car shop towels, non-woven polypropylene (NWPP) and linen. Think—dish towels, T-Shirts, pillow cases, sheets, and scarves.
Pro Tip: You’re going to want to use two layers (four is even better) of these materials to make your masks truly effective.
Why these materials? They’re breathable, accessible, and easy to work with! Breathability is key. If you can't breathe well through the mask you are more likely to adjust it.
Synthetics, polyester, spandex - These are bad ideas because the virus can survive on those surfaces for a long period of time.
(MUST be sandwiched between fabric for safety)
Coffee filters, A 1900+ furnace filter (2 layers), tyvek, vacuum cleaner bag, non-woven polypropylene (NWPP), unused mechanic/car shop towels
HEPA filters have glass particulate that you DO NOT want to be breathing.
Wearing a mask does not mean you do not have to practice other recommended activities: stay at home unless going out for essentials/exercise, avoid groups, maintain social distance of 6+ feet from people, wash your hands, do not touch your face.
