I don't like it [SEP] I have to say this is a mask I don't like. First off it had a chemical in it that burned my nose when I first tried it on. I am asthmatic and have reaction to all kinds of allergens as well as a sensitivity to certain chemicals. So the chemical smell was not a good thing.  I washed it in anti-allergy laundry soap and let it air dry. I tried it on this morning and the smell was gone but my nose still stung so something is still in the material.  I do not like the wire for the nose piece. It feels like it is just a round piece of wire which doesn't hold to nose well.  It also fits small from nose to chin.  Over all I wouldn't buy another mask like this one.  I give two stars only because i had no issue with seller. I will wash again and probably just keep this one at work for times I have to go into the shop or outside for short short periods of time.  This is just not a go-to mask for me.
