Home made mask info

Today they said it is OK to wear a mask to the store. I wouldn't recommend wearing one to the bank however . . .

Here is what we have been making:

Not using hair ties or double side tape.

I am using furnace filter media N=?

I used a pc of 14 gage copper wire, ends bent to snag around the nose fabric - this is key
to getting it to seal.

Good luck everyone!

A bunch of folks in our town have been making masks and delivering them to the local hospitals. They aren't for use with covid-19 patients. Apparently the hospitals are happy to get them. I read where they take about 45 minutes each to make.

I also read that cut up vacuum cleaner bags apparently do a pretty good job (95% effective) filtering 1 micron cooties. Of course the virus is much smaller than a micron, but even for sub-micron virus sized things the vacuum bag material is 86% effective. Compared to a cotton t-shirt at about 50%. Info is from tests conducted by Cambridge Univ. And, BTW, even the common dishtowel can filter out almost 75% of sub-micron particles.

Yea I intended to use vac bag as filter but then I read that it has too much restriction, so the air just goes around it.
I had a spare furnace filter & dissected it for the media. When I breath thru the mask it collapses a little so I think it is doing something.
Everyone stay safe!

Just a touch of mask humor....... :LOL2:

A mask information article in the ATLANTIC. Seems on point.
Be safe.

Just be sure to use a new one and not a used one.

I saw it mentioned about using the blue shop towels as filters.
One thing that I have noticed with people wearing masks, if they aren't worn properly, and don't seal, they might as well not be wearing anything and offer little to no protection.

My GF was a seamstress and she made some, they look like what I called a "Uni-Bra"
