One helpful Netizen in China’s Northern region, who endured the high levels of air pollution along with the rest of us, posted a before and after picture of the face mask he wore over the past four days.
The man said that he wore the same mask for four days and was outside, exposed to the haze for only an hour and a half every day. The picture shows how the mask has changed color from the white it comes in, to an off-gray color. Not a nice thought for those of us without masks. Hope our lungs aren’t an off-gray color today.
