terrible
I bought this mask for the occasional use. For some reason-I assumed that it has to be some filter inside to filter polluted air, but the mask is only piece of cloth. I washed it and it shrunk to half size and the pretty pattern faded accordingly. I will post the photos to prove it. The description on the box says: filtering efficiency depends on proper fitting. It doesn't fit, period, and cannot protect. Very expensive. I will return it.
