“Breathing and talking generate particles around 1 micron in size, which will be collected by N95 respirator filters with very high efficiency,” said Lisa Brosseau, a retired professor of environmental and occupational health sciences who spent her career researching respiratory protection.

Health care precautions for COVID-19 are built around stopping the droplets, since “there’s not a lot of evidence for aerosol spread of COVID-19,” said Patrick Remington, a former CDC epidemiologist and director of the Preventive Medicine Residency Program at the University of Wisconsin-Madison.

Fact check: What's true and what's false about coronavirus?
Size matters, but not how you think

But that’s not the only logical flaw in this claim.

The N95 filter indeed is physically around the 0.3 micron size. But that doesn’t mean it can only stop particles larger than that. The masks are actually best for particles either larger or smaller than that 0.3 micron threshold.

It has to do with how particles of various sizes travel. Small particles are subject to Brownian Motion, which causes them to bounce around like a pinball, which makes them easier to capture since they're unlikely to move through the filter in a straight line.

>What's the /sci/ence behind this when the virus is already small enough to pass through an N95 mask?
So this has already been cleared up in the thread, but the ideal if a respirator isn't available is to wear a mask with decent filtration ability underneath a well-fitted mask, which will result in a seal and give similar efficacy to a respirator.

.3 microns is the size it works worst at. It works better above and below that. There are two competing factors in stopping a particle, size and mass. Smaller particles have less mass and are easier to stop due to that. .3 microns is the point where the two effects achieve a minimum of their sum.

This doesn't matter at all. N95's working principle is not a filter, or anything similar, educate yourself. I've always been wearing a disposable mask over my N95, because I like to keep it as clean as possible. I'm surprised the rest of the world is barely catching on to my standards of back in March.

>> No.12695257

I'm curious how wearing a loose fitting surgical mask over an N95 alters the efficacy. The majority of air goes around the edges of a surgical mask. That could result in particles hitting the respirator at an uneven rate.

>I'm curious how wearing a loose fitting surgical mask over an N95 alters the efficacy.
Whenever you touch your mask, you touch the surgical one instead of the N95. Then when you remove them there's less cross-contamination risk because the N95 is untouched.

Nothing about this pandemic will be answered truthfully until a decade has passed after it ends. Only then will it be so far back in people's minds that honest research and data can be released. No politician wants to give their opponents fodder for campaign ads so the narrative will always be "We did everything right" and any flaws were due to interference by people of another ideology.
