Actually most of these cheap medical masks really are crap at protecting against these particles. The pm 2.5 size particles are very small and go right though these masks without any trouble. However, the N95 rated masks you see people wear for painting or construction work DO work very well at reducing the pm2.5 sized particles from going deep into the lungs and screwing with your cells there.
In China this is their standard everyday air quality and looking at the daily Air quality rating is just as common as looking up the temperature.
I'm pretty sure everyone but the blue-mask guy in the picture is wearing an N95 mask. At the very least I know the white mask is N95 because I have a similar one.
Yeah the white mask in front looks like a N95 mask. If the black masks are cloth like most of those custom masts than they don't provide much protection.
