Coronavirus: effectiveness of types of masks and manufacture of a homemade respiratory mask

[Macro]

I do not know. It is an endowment from my employer ...

An infox * that I had missed: the looping of CO2 from respiratory masks (FFP essentially, the others do not have enough dead volume to cause a loopback) ...

* in fact it's a half infox, FranceTV is trying to be smart to restore "the truth" but ... try to play sports with a filter mask (like FFP1) and you will see if you do not miss O2 !! https://mobile.francetvinfo.fr/sante/ma ... 75859.html

By cons when we are drunk it's nice: we recycle free ethanol!

In any case, bravo the French !!! Is there a faculty that delivers doctorates for faults in Frenchology?

There are still bankers who have humor (seen in Belfast)

The thing that circulates on RS ...

Honest I think it's too big (too coarse ribs) to be authentic ... Basically the message does not care about the mouth of those who do not want to put a mask ...

If you really have nothing at home, you have this solution!

It turns on the RS ... not checked the scale but it seems plausible (I think the virus is smaller still) ... except that it is wrong since the virus does not fly alone: it is contained in particles of liquid or fine particles ... much larger!
