Air filtering devices, especially designed to be inserted in the facepiece of the mask. The filters remove from the air passing through them toxic and/or irritating chemical vapors, gases, and particulate contaminants (dusts, fumes, mists, fogs, and smoke), including biological organisms likely to be used in warfare. They may filter industrial dusts, fumes, mists, fogs, and smoke, but are not designed to remove industrial type gases or vapors.
