Respiratory Face Mask

Protect the wearer from inhaling harmful dusts, fumes, vapors, or gases. Respirators range from relatively inexpensive single-use, disposable masks to more robust reusable models with replaceable cartridges. Two main categories: the air-purifying respirator which forces contaminated air through a filtering element, and the air- supplied respirator in which an alternate supply of fresh air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants.
