China is on a massive public relations offensive. I don't give a crap so long as they send the supplies, but don't let's forget the realities here. I'm not going to forget they hid the truth from the world, a DELIBERATE action, not a mistake or chance, and even punished their own doctors who were trying to blow the whistle on the new and different pneumonia scans they were seeing. I have a really long memory for every deliberate injury to me or mine, and so should everybody else.
They also want access to our ports and infrastructure. That's what some of the recent agreements have been about. Don't be naive.
N95 is better than N99 for medical purposes. There have been a few articles about it.
KN95 is bigger holes than KN99, how this can be?
KR100 costs 0.2-0.6 E lasts 8 hours of full wear and is much better,
P100 simple costs 0.6-1 E and can be worned till 72 hours from first worn
problem, simple masks are not reusable,
P100 textile with respirator costs a little bit, but reusable if you have spare filters,
ok P100 with filters is just working mask
European norms per product type
EN 136:1998 = Full-face masks
EN 140:1998 = Half masks and quarter masks
EN 143:2000/A1:2006 = Respiratory protections – devices withparticle filters
EN 149:2001+A1:2009 = Particle filtering half masks
EN 14387:2004+A1:2008 = Gas filters and combined filters
EN 14683:2005 = Surgical masks

N95 and KN95 mask is FFP2 category
https://multimedia.3m.com/mws/media...filtering-facepiece-respirator-classes-tb.pdf
mask that is holding bigger than 0.120-.0.130 nanometer diameter,
It is considered the minimum diameter for achieve safety to coronavirus,
FFP2 KN95 N95 is such
