Hmmm. I wonder if anyone has looked at which materials create the most static charge, and whether it is maintained in high humidity (breath) conditions. I somewhat doubt the latter, as such a charge is not a permanent (or semi-permanent) “electret” effect. (Electret microphones work ok even though obviously receiving a lot of hot humid breath in use.)
I’d think that surely by now someone has looked at what materials are best for homemade masks.
Of note, breathing through flannel (shirt material) in the crook of one’s elbow seems to almost entirely remove most odors and scents. (No to be gross, but, compared to a virus, how big are the “particles” floating around after one stinks up the bathroom? Or passes gas. Or what’s the final particle size of the air freshener aerosol spray used to combat that?)
Turtlenecks can also filter out smells and fragrances.
And they are very convenient.
