hongkongfooey said: Stay indoors : Bah ha ha ha, the stupid, inane, pathetic HK government tell you to stay indoors on really bad days where the air quality is almost EXACTLY the same as outside ( unless you have air purifiers ). Are people really that stupid to think their flats ( especially here ) are air tight
actually ... some just might be that dumb.. Coz they think that holding a hand in front of your nose will protect you from street level pollution - you see it all the time...
I however advocate the "place extended index finger across your nostrils" method, which realiably filters out any pollutants bigger than a broadbean (or even a pea for that matter) and looks even more ridiculous
@Roxy_Chick_1989
sad but true, the full face filter picture you posted is the only way of getting clean air outside. Not that I'd see anyone wear them, because air pollution doesn't cause acute pain so most people try to ignore it ....
