Certified or not (or even fake) they will still protect you and others around you to varying degree.
Certified mask doesn't mean you won't get infected, nothing is 100%.
The certification weren't even tested to protect you against Covid19 virus specifically anyways, so the 95% doesn't technically apply. (I'm not saying n95 is useless against Covid19, it is probably the best that we have against it, but focusing too hard on the "95" is a waste of time)
Similar to how there are no scientific number against how effect are cloth masks and DIY masks.
The point is, they ALL help.
Heck, unless the fake n95 has a big hole in it, it'll probably still work better than a medical mask.
Agreed.

The NPPTL lab results show 1 out of 30 respirators with an 89% filtration efficiency. The remaining 29 respirators performed between 96-99%. That a heck of a lot better than any surgical mask.

If you want to reduce the likelihood of fogging, get the 9210+ because it has an embossed top panel. The 9211+ has an embossed top panel and exhalation valve which further reduces fogging.
Thanks! I was looking into getting these:

Exactly, just use common sense.

These are labeled non-medical use meaning they will likely fail a personal fit test due to gaps, and filter penetration isn't guaranteed. However they'll be better than a face covering or a cheap procedure mask, just don't count on it for high personal protection like a fit tested 3M N95 or F2100-11 Level 3 mask that wraps tightly around your face.

Those masks have a filter efficiency of 5-10%, assuming a perfect fit.

The KN95 respirators in this thread are 89-99%. It's a completely different product.

KN95 have, as the name suggest, a 95% filter efficiency, and only if properly mask fitted. We are using these and they have extremely poor quality control.

I am confused now.

This person said so below:



@chatbox The above person said to get an exhalation valve based mask to avoid fogging.
I never had fogging issues with any of the 3M n95s im fitted for including the Aura. The only fogging issues I have are with the normal blue face masks made from China due to the wire being not as wide.

The vent is for easier breathing if you need it for the elderly to be more comfortable.

Damn those prices are 4x what they were for those filters in March.

I would reccomend the cartridge filters over the round ones, cuz the the filter are exposed and will clog up faster.
