The goal of our mask is to stop droplets. So you want to go for something that filters those out.
|
||
|
|
Then again, you need to be able to breath through your mask, so we want fabric that breathes, without letting droplets through.
|
||
|
|
|
||
|
|
In addition, we want the inside to be comfortable on our skin. So here I'd suggest a tightly woven cotton or viscose/rayon.
|
||
|
|
For the outter fabric, cotton again, or a tightly woven wool.

Note that fabric that is *breathable* is not the same as fabric your can breath through.
|
||
|
|
There's many so-called waterproof breathable fabrics — or MBFs — that are used for outdoor gear because they
|
||
|
|
repel water and are *breathable* but would make a poor choice for a face mask.
|
||
|
|
Look no further than your umbrella for an example. Chances are it's more from a fabric you can breath through,
|
||
|
|
but only with substantial effort, which would not work for our face mask.
