It may sound like a "what???" thread but soon you will know more about masks and particularly reusable ones. I'm getting my reusable masks from Europe. They are not anywhere near as good as n95, but since n95 are several months away from public availability, better then nothing. People need to clearly understand something. They MUST BE PURE COTTON MASKS. They need to be boiled to kill everything and normal plastic based cloths can't take that. Plus the additional ironing and several steam puffs at full power pretty much destroys ALL non exotic plastic based cloth. This is critical because on the rush to buy them, there is no public knowledge. Now YOU know and pass it on. Anything you want to know about masks, ask me. .

I read an article yesterday about DIY masks that quoted Peter Tsai who, according to this article, was instrumental to the development of the N95 mask. He was suggesting non-woven material (ie: like the blue shop towels found in Canadaian Tire) as a possible material: www.washingtonpost.com/lifestyle/wellness/masks-diy-coronavirus/2020/04/01/20830f5e-7420-11ea-85cb-8670579b863d_story.htmlPLEASE NOTE: I'm not putting this here to contradict you Cranky. I'm just totally confused. Just this past Monday, Teresa Tam was saying that the general public shouldn't be wearing masks. Yet Michael Garron Hospital has ordered DIY masks from a group in Toronto to give to visitors & discharged patients. Wish they could get together with one message.

Yet Michael Garron Hospital has ordered DIY masks from a group in Toronto to give to visitors & discharged patients. Wish they could get together with one message. Do not be confused and absolutely follow my lead. All my life, through a few thousand directly and a 5 figure amount indirectly, masks were the first line of defense in metal, paper and woodworking environment that I managed. Through directly talking to engineers who made the masks to my implementation....I'm the "for masks" guy. The other issue of do we need them now? Absolutely. I'm heading out for a shopping trip to Buffalo....no...wait. cancelled. Later on tonight, I will post a running battle I have at HF about masks. In it, the reason, logic, how to, issues, differences and more. Look, we never met, if you don't wear one, it wont make a direct difference to me, but I feel that I need to push something that I fully believe in because it may be your life, or my life, or someone else's life that may be saved. Later on...

Two posts on the arguments I made on HF about masks.
Some of the more important are bold.
I feel I need to push masks based on my knowledge, actually, expertise. As a manager/CEO/owner, I made it my business to thoroughly study the problem/issues as much I could and DICTATE safety policy. After all, the safety of my people was ALWAYS my responsibility and the blame stopped at MY desk.
If I can push this and save even one life, I would would feel humbled and kiss the sky.

So by expired masks, they mean that the mask still works but the % is lower? When I hear "expired" on the news it comes across as useless. I have never heard anyone explain it until I read your post.
I was going through my painting supplies recently & came across a 3M N95 mask that I bought at least a year ago because I was sanding furniture & drywall. I only wore it a couple of times.
Am I correct in assuming that this would still be effective?
Interesting details about cars. I was thinking about getting my snow tires off but then I realized some stranger would be sitting in my vehicle. Ugh!
Until I can find someone that can do it without getting in the car, the snow tires stay on. I'm not going anywhere anytime soon.

Until I can find someone that can do it without getting in the car, the snow tires stay on. I'm not going anywhere anytime soon. Expired SEALED masks are ABSOLUTELY NOT useless. Their mesh structure is fine, but they may have additional protections that degraded. One of the major failures is the rubber band degrading because of ozone. Which is not really that much of a failure if they are sealed. Any Canadian politician who opens their mouth about masks should be taken to a basement...and get acquainted with a phone book. A thick one. Your mask.....unless they were sealed, throw them away. When you breath, you introduce moisture that will then combine with whatever is trapped there. Let's say it was wood. Now you got tiny wood particles that got moisture and now you got mold. Mold directly into the path of your breathing. Not good. Plus the enormous time that they are in the open has introduced all kinds of particles on them. You don't really want to give them a direct path to your body. Sorry. Do you or your wife or your family sow? Read my post on making masks. It's NOT as good as even out of date masks, but, it's something. Always remember that you are playing the odds. The more and better protection, the lesser the probability of infection. Here is a site about DIY masks. The choice of cloth is absolutely critical and there is not enough knowledge out there about what to look for. Again, I touched on the subject in my posts above. smartairfilters.com/en/blog/best-materials-make-diy-face-mask-virus/

Thanks very much for the info.
My sister asked for the this link & I passed it along a couple of days ago. She's an excellent quilter do perhaps she can come up with something.

Make sure she uses a sewing machine with very fine pattern and don't use pins. Remember it has to be pure cotton to be able to boil them. Post it....it's our personal war weapons.

I went through all our pure cotton cloth we have in the house. With a flashlight, i could see sharp points of light through ALL of them including those two layers of t-shirts. Only my heavy fleece sweatshirt showed very sporadic points of light light and when I put two together, no points, but it was definitely hard to breath through it. Obviously easier if I had more fabric area by design. Also no boiling since it's synthetic.
The sharp points of light means there is clear open space for .3 micron to whip through unimpeded. Probably up to 10 micron. The purpose of the mask is to present an obstacle course to the smallest droplets and hope they stick, not a highway.
I'm getting a whole lot of "huh?" about the tests on that site. While I fully buy into the fabric mask, I think it needs more search for right fabric and then the right design.
This is right up my alley as far as material research, including front and back lit stereo microscope, but....there are no stores open and the search can be worse when the cure.
All those DIY masks out there....well....I'm wondering about their material choices.
Stay tuned...

This debate about the public wearing masks is OVER. FINISHED. DONE.
All the talking heads on tv, the CDC and WHO can go eff themselves with their lies.
Anyone who keeps debating "we don't need them for the public" is a flat earther.

A mask made from a bra.....like NOBODY will notice that. I'm waiting for the cloth stores to open to get some half decent cloth to make some. I found a non cloth solution AND a very tight fleece that I "should" use, but need to see it first. It may also be found ion heavy sweat shirts. No use making a mask that barely works.

Here is a running discussion about making masks in Ontario. What irks me is politicians saying "we could do it right here" which is a great soundbite, but full of baby brown stuff. Then you get the masses screaming "sure we can", but too many of the masses are as clued about running or building a business as my pet hamster. Maybe less.
