i do not like it [SEP] i have to say this is a mask i do not 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 does not hold to nose well it also fits small from nose to chin over all i would not 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
