Are these KN95 or N95?  I am hearing that N95s are the preferred (allowed?) version to use in hospitals but I don't know the exact reason (KN95s are from China, so quality control may be a part of it)

I would clarify KN95 are the Chinese-version, pretty much all the masks are "from China." 

This article discusses how the FDA banned some KN95 masks that failed FDA tests:

Here is the list of FDA-approved N95 and KN95 masks:

Here is a list of FDA (known) manufacturers that are NOT aproved:

And a reminder that masks with a little plastic respirator valve are not encouraged in public settings -- they protect the wearer but enable the wearer to easily breathe out virus. I have a few of these from previous years (due to forest fire concerns) and the recommendation is to wear a surgical mask over the valve to protect others.
