#COVID #BringBackMasks

@rchusid Now we just need @WHO to mention #N95, #N99, #P100, #FFP2, #FFP3, #P3, #KF94, and/or #KN95 #elastomeric #respirators -- the ones which *work* -- rather than just vaguely saying "masks".
Cloth & surgical junk masks are 30% effective -- better than nothing.
#N95 and reusable #P100 #elastomeric #respirators are >95% effective -- MUCH better. And they're cheap enough.

Wide spread use of masks, not respirators would significantly reduce transmission. It is almost as good as ventilation, filtration, and air disinfection. But the latter can be achieved without infringing on behavior and without the very annoying social barriers masks put between us.
Why isn’t WHO talking about these much more socially acceptable interventions?

One thing that I would like to add is that earloop respirators(such as the KN95 and KF94 formats) have no downsides when compared to surgical masks. They offer better filtration, easier to breathe in, more protection(2x-7x) and easier to talk in. So to me there is no "cost" to moving the minimum to an earloop format. N95's and headband respirators start to have some trade offs. Widespread use of earloops would even be more impactful at very little cost

I found disposable #N95-style headband respirators a pain to take on and off.
However, the 3M 6300, which is a #P100 #elastomeric, was *easier* to take on and off as an earloop mask, because the neck part of the headband has a "snap" or fastener in the back. REALLY easy.
Earloop masks have more leakage around the sides than headband masks, according to studies, due to wiggling ears. And the stress on the ears hurts.
So I now recommend #P100s

Tested 2/18/22. 99.73 filtration efficiency. Not too shabby! 😷
