KN95 spec allows a percentage of unfiltered air to be inhaled which kinda defeats the purpose no?
Every mask will allow some fraction of unfiltered air to be inhaled. The question is: how much is permissible?

Wouldn’t that be true of any mask?

#13Given that there have been various reports of fake masks and test kits coming out of Chinese factories, I kind of don't blame them for this one.

#15Are people so cynical as to believe the US Gov will arbitrarily deny necessary medical supplies?
There is more variables at play than just '# of masks'. It is necessary to ensure the masks actually work, as defects will cost the lives of frontline workers.
My country, Canada, is doing the same thing: https://www.chroniclejournal.com/news/national/canada-will-m...

I'm not sure what this has to do with anything. If they are fakes, they could just as easily be falsely labelled N95 as KN95, right? What am I missing?
The FDA would also not allow N95 masks bought here if they weren't from an approved facility.

#17Kill you once by spreading virus with its social media control. Kill you 2nd round by selling you faked products. Is this kill you the third cut by doing a PR war that not accepting this Trojan Horse is political.
How many cuts you need to kill the western world.

Yesterday, I read some paper from 2010 which found near identical filtration results for one type of N95 mask vs. 2 types of N99 mask... Basically none of these masks will filter all the particles, hence healthcare worker will eventually infect themselves unless you go full warzone (e.g. hazmat suites for everyone). All of this stuff is about managing risk (as is running around with simple masks and social distancing).

Exactly. So what's the relation between this article about fake/inferior masks from an unapproved factory, and the parent article about a variant standard of mask (KN95) that hasn't been approved in the USA?
