Not gonna lie, that website (including that it's "selfrely.com") looks extremely sketchy. I worry even having clicked on it.

Starts right there with the leaders what they refuse to say, refuse to do, and what they do symbolically or not. Once shown the ignorant, easily impressionable, sheep, etc. etc. can run many different ways and the polarizing leadership in the US has had a field day in seeding this polarization.

It says that if you have "symptoms" you shouldn't use an exhalation valve.
The RULE with CV-19 is that everyone can transmit as if they have symptoms.

END.

I thought you still can transmit when you are asymptomatic.

That's what @FlyBitcoin said

What about exhalation valve masks that have one or two layers of liner on the inside, over the actual valve?

FlyBitcoin

Nobody else will know that.
Wear a paper mask over the valves or wear one without valves.

Huge spike where I live. I watched it play out with the deniers full bore. Tons of no masks since Memorial day. Just in full follow up the ECMO consult I got, eventually got better and is now on the floor with oxygen. The patient did not need anti-thrombotic or steroids. Also was a teenager. Just got a notice about a 40 something with cystic fibrosis and Covid+. That may not go well.

I just took a field trip to my garage and took pictures of 2 types of N95s with valve. The first one has a valve in the center, with a circular rubber flap. As you can see where I used a nail to demonstrate, when you exhale the valve opens and allows air and droplets to escape in all directions unimpeded (perhaps blocked a bit straight in front, but what goes up will come down). There’s no cloth or filter; when that flap opens it’s open. The second does have a bit of directionality but not much -- air/droplets can go out down/slightly forward and sideways.

These simply aren’t meant to prevent droplets from leaving the wearer’s face, which is fine for most dust/fume/industrial uses. Whether someone who makes money selling them calls that out or not.

I’m not saying there aren’t others that do have some sort of filter or cloth in addition to the valve (but I don’t understand that completely, since the whole mask is the filter), but virtually all of the ones I’ve seen people wearing are like above. As Flybitcoin says, a simple cloth or mask over it solves the problem.

At this point, anyone in a position of authority advocating non mask use should be criminally charged for endangerment of public health and the like. Same for any organizer of large indoors events with no masks, and any public official.

I am actually surprised that the medical associations have not demanded public health measures to curb the spread. I would have threatened strikes of the health care workers statewide to deal with this lunacy.

Asymptomatic Transmission, the Achilles’ Heel of Current Strategies to Control Covid-19

Unlike police departments, healthcare workers tend to show up to their job in suboptimal conditions all the time.

And when someone quotes the one WHO person as saying asymptomatic transmission is rare -- she was being overly scientific and only referring to "never symptomatic", not including the much higher spread prevalance from "mildly symptomatic" (like the doofus in Texas that held a surprise party with a mild cough he thought was from working construction, until he put 3 relatives in the hospital) or "pre-symptomatic" (the tons of people who feel fine today and start having symptoms tomorrow, when it's too late to go back and wear that mask around all the people you breathed on yesterday) cases.

It all boils down to THIS being the one factor that makes this virus so different.
It is less lethal than SARS-1 and MERS, so we let our guard down at first, thinking it would just fizzle out like the other two. But by the time we figured out the asymptomatic part, it had already broken out around the world. I don't think we will ever have a way to identify the first day one becomes infected and contagious.

In the end, this is why the mask is such an essential piece of control for this virus, and we cannot settle for "features" like one-way valves.
