In reply to: Just an FYI, Osterholm came out today and posted by Steelhop
movement in or out."
Let me add he didn't say there were issues with n95 masks and that is my input. But N95 are more expensive, need to be well fitted to work and need to be either cleaned or replaced regularly.
if he was talking about just an individual or if they dont matter if everyone is wearing that type of mask.
Either way, I think its been known for a while that the surgeon mask was not nearly as effective as an n95. Yes, they are more expensive, its one of the reasons people like myself think Trump failed us originally by not making a full on effort to make more of these types of masks. More supply would presumably make the costs low. Biden may have to start doing the same thing, but the delta variant outbreak is no where near where we were pre vaccine obviously. But it would be nice if N95s were offered for free to those who cant afford them.
Or is there a difference?
I have a couple boxes of KN95's.
An N95 has to be fit tested so their is no leak. Males cannot have much facial hair as even stubble can interfere and cause a leak.
A KN95 is made of the same material but it is not fit tested so there isn’t a tight seal.
chinese approved. They are supposedly similar but i would assume N95s are a bit better. But the CDC said KN95s are a suitable substitute.
I would guess the hierachy of masks goes
cloth covering
surgeon mask
KN95
N95
SonoMask
Israeli grade Gas mask
Mostly kidding.
