COVID - How to protect ourselves

[Kurt]

Regarding the mask/nose issue, the masks we use in Asia (not sure about US since I've never worn one there) have a band across the top of the mask. You are supposed to bend that band to fit closer around your nose. 

I was wearing them all wrong. I kept complaining to my wife that when using a mask outside and having to wear my reading glasses, like at church, the glasses would always fog up. When I started bending that band, the problem cleared up almost completely.

See post #19 of mine above.

In my non-expert opinion I think the biggest design flaw in the DIY masks is not having the little metal strip that forms and seals around the bridge of the nose. My experiments back this up, as does your experience, the gif above with the mist clouds and my research that says a big issue with masks is people don't seal them correctly.

There's 3 things (probably more) that you can use to make the metal seal strip:
pipe cleaner
a straightened paper clip
folded/rolled foil

Then use some duct tape to tape it in place.

The image below shows the little metal strip that you're supposed to bend around your nose to fit...and I believe it's a big deal:
