We understand your needs and concerns with respirator safety especially when protection is essential for different types of emergencies including chemical/biological and nuclear threats. We carry respirator masks that are first choice for federal, state and local government. An air-purifying respirator gas mask will filter or clean chemical gases and possibly particles out of the air as you breathe. We offer half-mask respirators and full-face respirators that protect against most vapors, acid gases, dust and fumes.  A full-face shield protects the face and eyes from irritants and contaminants.  We offer Survivair respirator gas masks. Gas masks do not provide oxygen and is typically designed for use in emergency exit in low oxygen levels and from hazardous atmospheres.
