Mask Safety.

I'm seeing a lot more people using masks. That's good. Unfortunately, I'm also seeing a lot that are using masks that only protect the wearer but not those who may come in contact with someone infected who is wearing one.
Notice the valve on this mask. It allows unfiltered breath and coughs to be expelled by the wearer.

The valves are for easing exhaust pressure.

These canister masks have the same issue.

If all you care about is your personnal safety, these masks are fine. For true two way protection avoid them and please inform others of this issue.

The more you know.

I have such masks and it never occured to me the exhalation designed into it.
Of course, if you know you have the virus you should be in quarantine. But you can be contagious without showing any symptoms.
So, masks that cover your breath in and out is needed.
Thanks for pointing that out.

That, in its essence, is fascism--ownership of government by an individual, by a group, or by any other controlling private power. -- Franklin D. Roosevelt --

They say that there's a broken light for every heart on Broadway
They say that life's a game and then they take the board away
They give you masks and costumes and an outline of the story
And leave you all to improvise their vicious cabaret-- A. Moore

Actually, the issue at stake is patriotism. You must return to your world and put an end to the Commies. All it takes are a few good men.

Exit polls not involving George W. Bush or Hillary Clinton tend to be quite accurate.
