i'm watching the first short version first.

he looks like he's been through a really tough time, my heart goes out to him. in the intro he almost breaks up.

ok, really, it doesn't take that long to watch the short version.

i don't want to paraphrase or misquote him.

the longer version i'm going to have to wait to watch it.

I felt bad fr him too! But, I appreciate his giving us this information.

Heat the masks to 160f for 30 minutes. The Covid particles begin rapid decline at 132.5f at a rate of 10,000 particles per 15 minutes according to WHO scientists. Google it for confirmation instead of relying on my sources. Sounds like cooking? Yeah well it is. The particles are protiens and they are covered with a fat layer. Sounds like boston butt to me. The problem is the mask materials might not like the 195f I want to see in the middle of my BBQ. Polymers have real failure issues past 160f-170f. This includes vinyl siding and elastic mask headbands.

I doubt that microwaving would sterilize the mask before it destroyed it. Microwaves seem to be less effective in killing small things. How do I know this? Ants got into a coffee cake that I purchased last week, and I tried microwaving the package to kill them. The coffee cake got hot, but some of the ants were still moving. :ep In the end, it was steam from the coffee cake that killed them, not the microwaves.
You would not want to know how long fleas can last in a microwave. Nor would you want to know how I know.:eek:

I have been making masks for anyone who wants them, basically, but the intent was to send them with my ex-daughter in law to the hospital where she is a nurse, in the ER, no less.
I have found that you can split the wide elastic if that's all you have. The instructions I got called for 1/8" elastic, but that is as rare as hen's teeth. I've been cutting 3/8", and some wider I had, as well.
Also, an article I read today suggested, as an N95 substitute, for personal use, you can use a piece of hepa quality furnace filter, in between two layers of cloth. Needs to be able to separate for cleaning.
Now I see that nurses and others who have to wear those masks all the time are getting open sores behind their ears from wearing the elastic type. So now people are making little strips of fabric (or crocheted), with a button attached to each end, so they can fasten each ear elastic on the buttons in back, not around their ear. Sounds more complicated than it is. I'm going to make some of these to go with my next batch of masks.

Also if anyone is making these that does not have elastic, you can make fabric ties that tie up in the back.

I would think that pieces of a HEPA vacuum bag might be better suited to that application.
