Nice. So force applied being much higher for KN95 means what? That the mask is theoretically tighter but also much less comfortable?

[how]

A surgical mask is basically open from the entire top and sides and welcomes all airborne particles. N95 masks, even if poorly fitted, will be a much tighter fit around the face, and even if not sealed 100%, will significantly reduce airborne particles compared to surgical. IMHO.

Yes but how much I have no idea.
I had to wear respirator masks for many months. Even a perfectly fitted one is not 100%.
With a beard a fitted mask (N95) will still fit better than a surgical mask. It still filters better so based on that I would say yes but that is only a guess.

So the reasoning is that a 3 ply mask is more porous so the air you breathe will come through the mask. An N95 is less porous so if there is any gap unfiltered air will come through that path of least resistance. So that's why a surgical mask may be better for a beard or if you were not fit tested. Many people still opt for the N95 and try to make sure it's tight but still, everything depends on the mask, beard person
If you do wear a mask make sure to wear it properly. Follow this link for instructions on how to properly wear and remove a face mask

Chinese version of an N95. very slight differences. Many countries have their own regulations. Similar to UL CE

[Yammer]

Didn't see anyone mention N95 until your post. KN95 is not N95.
KN95 is Chinese standard and not equivalent.

Chinese.

There have been many KN95s that have lost FDA approvals over the last few days.

In fact it's not even being allowed into the country now.

Someone else is selling KN-95 masks with a certificate from victesting.com
Anyone know if the company is legit?

Does anybody have any tips for fitting a respirator mask. I'm having trouble on two masks so far sealing it by the nose area.

Is there some sort of tape that I can use to close the gaps?

Wont a surgical mask help if someone sneezes near you (the big droplets wont go into your mouth/nose)

The concern is that the droplets aerosolize and can get past a surgical mask. They aren’t sure how much of a concern this is.

I followed all instructions but wasn't successful. I was successful previously with a mask that had this little foam piece by the nose

the N95 has that foam piece

Any suggestions how to get ahold of N95 or KN95 in Toronto?

Since I can't get the masks that I have to fit I use it even though it leaks. The issue is that my glasses fog up.

A trick I learned a few years ago is to take regular dish soap and smear a very thin layer onto the glasses (both sides). Let it dry then buff it out with a cloth/tissue until it's perfectly clear. This will prevent any fogging up until the soap gets washed off.

Works extremely well. Try putting your glasses in the freezer with soap on only one lens for a few minutes and take it out to see the full effect.

Thought I'd share in case anyone finds it helpful.

Did you try having it sit higher on your nose? Often that's a mistake people make.

Question is if you won't, does the N95 still give some level of protection?

depends how well you pt it on, airtight etc. I noticed some times I can breathe just fine through it, some times I can barely catch my breath...
