ABSTRACT:
Shaped porous filtering structures of substantially uniform thickness and density particularly suited for filtration of gases and vapors comprising spaced adsorbent granules unified into a solid, self-sustaining, unitary, impact-resistant body by adherent binder particles. Respirators incorporating such structures as the gas and vapor filtration elements and methods for making the shaped porous filtering structures are disclosed.
