The thing I liked about these was the valve that allows better airflow (out) and filters the air coming in. (caution: If you are the one infected, it doens't protect others)
It also closes around the face much better. Of course there’s still airflow and risk of infection, but while a common paper mask is better than no mask at all, this mask is better than the ordinary mask.
Also, the mask comes in a very flat presentation, ideal for my bag. I kept it in the compartment where I keep a small emergency kit, and well, because of that it was there when I needed it.
Guys, the idea isn’t to go nuts running paranoid because of this. Just maybe use it in situations where you logically see a greater risk of infection. Besides this, it earns a place in the kit in case of smoke, dust, debris and dust after accidnets, atacks etc. Weights nothing, occupies little space and air being kind of important for you survival, it makes sense to have one around.
Here’s the link of where I found the pic, but I have no idea if the price is ok. Better to look around.
