3M 7501 / 7502 Half Facepiece Respirator

The 3M half facepiece respirator covers the nose and mouth and filters hazardous airborne contaminants to protect the respiratory system. It is lightweight, compact and easy to maintain. The straps stay fixed to the facepiece, so it sits in the same position each time it is worn, and the head cradle adjusts for an individual fit. Filters last 500–800 hours per set; only the cartridges are replaced, and the facepiece is reused.
