These are cheaper than you can get at most stores! They fit very well and are comfortable. I think these are the best kids you can get as far as N95.
Buy in bulk! I keep a couple of these in every BOB and at home & work. In any emergency that fouls the air, or if you are helping someone who is injured, you want to have these. I'll never buy unvented again. This is the way to go.
These are very good for any illness, pandemic, volcanic eruption etc. These are also a cheaper alternative to gas masks also, without looking completely crazy. I wear these also when working with paints, chemicals and sanding wood as well. Keeps bad things out of your nerves and lungs.
It does the job. Fits comfortably, I wouldn't mind having to wear it for extended periods of time (if I had to). Definitely spend the extra money for the vented masks. Even with the vent, exhaling gets warm, I wouldn't want to know how the non-vented ones feel.
