poor design
This mask has a valve that lets the wearer expel breath outward thus not providing much protection for those around them.

I wont be ordering any more of these.

Nice N95 mask with braided straps
I recently developed an allergy to the elastic straps on some of the 3M N95 model masks and was relieved to discover this N95 mask with braided straps. In addition it is built with a significant bulge that makes breathing easy. It is a bit large - not too large for my face but it comes very high near my eyes. Also the straps attach with staples and I was worried ...

Excellent for a person w/ glasses
Directs exhalation away from glasses on cold days reducing foggy glasses.

Strap is too short - makes the mask uncomfortable
It seems like its a one size fits all - but it isn't! If you are willing to modify the strap it will provide the seal around the nose and mouth comfortably

N95 Masks
They are good. Comfortable but a bit tight specially for those with big heads.

Cool and comfortable
For a mask that actually fits correctly (tight to the face) it is very comfortable. The vent keeps the mask from becoming hot and sweaty when worn for hours. I wear glasses and the metal nose piece when adjusted properly keeps air from escaping and fogging up my glasses. However the straps can start digging into the skin. I started wearing a baseball cap and had t...

Wish I could buy more N95 respirators
Glad I was able to purchase a box before the N95 respirators totally vanished.
