I bought this for my son who is a Firefighter. He complained that in smaller fires they don't have to wear their headgear but the smoke still bothers him. I am actually scared to wear masks that cover my nose and mouth but I tried this one on and I couldn't believe how easy it was to breath. The air flow is amazing and it's like you're breathing without anything on your face. I tried it when something was smoking on the stove and it really worked. It's very comfortable, you don't feel like you're wearing a mask at all. I can't even wear a hospital face mask without anxiety but I could wear this all day, no problem. I really like it and I hope that our son loves it.
