N99 Dust Respirator by Willson |
This lightweight and comfortable dust mask offers excellent protection against hazardous dust. The exhalation valve prevents fogging of eye glasses and improves the facial seal. This Model N99 has a superior full sealing flange (the dark area on the inside of the mask as seen in the picture) and is NIOSH rated to protect against 99% of oil-free particles down to a size of 0.5 microns. Made by Sperian in Tunisia. The stated price is for one mask.
