I purchased these after watching the towers fall on 9/11. Seeing all those people running unable to breath because of the dust and debris I thought a mask would be cheap insurance to keep around the house. I've since replaced these as the kids have grown. Although they are/were NBC rated I have no delusions they would be that effective against something like that.
I have a total of 2 masks available.

Looking for $10 each.
Here's the description from a online site selling these.

Comes with NBC Filter. This mask has been modeled directly from the British style with side-mount screw-on canister, and is currently used by the Canadian military as well as others. The masks have a very comfortable anti-fog mouth and nose cup that keeps the lenses from fogging up. The voice emitter makes it easier to communicate with the mask on. It effectively protects the wearer's respiratory tract, face and eyes against all known chemical and biological agents (NBC). The elastic and nylon head harness that terminates in a nylon pad at the back of the head makes this one of the easiest masks to put on. The deep set round lenses provide for excellent visibility 5D-rings for various configurations and heavy duty snaps and clips.
