Swirling Smoke carries solids along with gas. Usually these particulates are coated with chemicals created by the fire. As smoke enters the airways, it not only chokes off the air supply; it carries the particulates into the mouth, throat, and lungs. Tissues become irritated, lose their ability to absorb oxygen, and ultimately are destroyed. Suffocation and death follow.

Specially formulated material inside the pillow-like filter traps particulates before they can reach the mouth and throat. Breathing is free and easy; throat and lung tissues are protected. Much can be survived in a fire if the throat and lungs are protected from particulate matter; even serious burns can be survived, but a small amount of smoke can damage for life - or even kill.
