The 3M 4279+ Half Mask is a maintenance-free respirator for work around organic vapours, gases and hazardous particulates. The cartridge and filters are built in, so it is ready to wear straight from the bag with no parts to fit or change.
It is lightweight, well balanced and low in profile. A centrally positioned exhalation valve helps reduce heat and moisture build-up, which makes it a practical choice in hot and humid conditions.
