Researchers at Cambridge University tested a wide range of household materials for homemade masks. To measure effectiveness, they shot Bacillus atrophaeus bacteria (0.93-1.25 microns) and Bacteriophage MS virus (0.023 microns in size) at different household materials. They measured what percentage the materials could capture and compared them to the more common surgical mask.

I saw that, earlier! I thought...hmmm...not sure I want to use a vacuum cleaner bag, for mask making...lol.
I like the dish towel.
I wish they’d tested felt. I was thinking that would work nicely, in between outer fabric and lining.
I have felt that says Made in the USA.

After watching "Raising Arizona", my daughter wondered if a pantyhose mask would work! 🤪🙀🦇

Nowhere can I find that states exactly what brand of dishtowel/tea towel they used. I’ve yet to see one that isn’t so loosely woven you can’t see daylight through them a mile away.
