This is great, and we should all applaud it, but what if you don't have a sewing machine? What if you want an N-95 mask, but they are all sold out?

What matters is the HEPA cloth filter, not how it attaches to your face.

You beat me to it!   

I was trying to figure out where to acquire the good material, and saw this article.

Almost no vacuum cleaners require a bag anymore. DOH!

As an ER nurse, I can critique this jury-rigged mask with one word: Nope.

It has gaps. You have to have a way to effectively seal all contact points with the face. Just one gap- a tiny one- is all it takes to allow a virus into your respiratory tract.

That is why, every year, we are fit-tested for N-95 use. Guys with beards (like me) are not allowed to wear them and must use CAPRs when providing any care for patients with highly-contagious respiratory infections.

You will also notice that N-95 masks are pre-contoured to fit the face. You can't just cut something out and mash it up into some semblance of a mask. You may as well wear a bandana for all the good that this jury-rigged bad joke will do you.

Stupid, uninformed crap like this is what gets credulous people killed.
