The Bielcor N95 B201 mask provides a good fit on your face with no detectable leakage, especially around the area of the nose. I know this because I wear glasses and other masks have caused my glasses to fog up but not this one. Also, when I place my hands over the outside of the mask and breathe in, I can feel the mask pulling into my face. I always feel safe when I wear the mask indoors with crowds about.
