Of course, you can also hold your breath for a vaccine:)

This is better than telling people not to touch their face, which is not a problem unless you touch eyes, mouth or nostrils, or eat with unwashed hands.

But above all pray (see tag).

Wrong. Unless you are in very close contact with a carrier, you are unlikely to breathe in the virus.

3M N95 masks captured over 95% of particles down to 0.007 microns. That’s over 10 times smaller than the coronavirus. What might be surprising to some is that the surgical mask was able to capture 80% of the tiny particles...

Here is where that maks fails - in the fitting. If the mask does not provide a solid SEAL against the face, air moves in around the mask.

The ideal mask provides the mentioned level of filtration, makes a solid seal on the face, is easily replaceable and in the long term, is not expensive. Currently, I have found these types of masks costing $10 for a two pack. Even if you dispose and replace once per week, a couple months supply starts to approach $100.

This is where I see an opportunity and I am using my 3d printer to develop a mask that is low cost (target $30 to $35), that provides HEPA 13 or better filtration, can easily replace the filters at a minimum cost, and is chemically resistant to detergent / sanitation / dishwasher safe. Yes they would be initially more expensive, but would last multiple years, and the filters could be even made at home but cutting up a standard HEPA house filter.

Ok, now test this one, this is what I'm stuck with:

The way I see it masks are more for other people’s protection than your own, especially in this case, you could be infected already. If you are breathing through your mask, you reduce the chance of giving what you got to others, at least by some factor.

...What’s more, they work surprisingly well even while people are wearing them...

This one has me stumped. Do they work better when left in the box? Do they work best for animals? What was this attempting to convey?

You don't necessarily need to capture the virus particles themselves, but you need to capture the liquid droplets that transport the virions.

The Lancet, Volume 361, Issue 9368, 3 May 2003, Pages 1519-1520, "Effectiveness of precautions against droplets and contact in prevention of nosocomial transmission of severe acute respiratory syndrome (SARS)."

Practice of droplets precaution and contact precaution is adequate in significantly reducing the risk of infection after exposures to patients with SARS. The protective role of the mask suggests that in hospitals, infection is transmitted by droplets.

I bought 40 3m 8511 masks 5 weeks ago, enough for my entire extended family to have 2 each, dirt cheap.
Everyone should be wearing them, everyone.
The only reason for not donning a mask are short supply, caused by industry outsourcing EVERYTHING they can overseas.
I will not be guilted for being proactive and smarter than the average sheep.

yes, It will scare people away from you at least 10 ft or more!
