3M™ Particulate Respirator 8233 N100 with Valve, is well suited for those who want NIOSH's highest-rated filtration efficiency (99.97% of particles to 0.3 microns) for non-oil based particles in a maintenance-free, disposable respirator. Designed and rated for workers and occupational use, the 8233 (N100) is ideal for heavy-duty jobs at work or at home. The NIOSH N100-rated∗ respirator reduces inhalation exposure from allergens, dust, bacteria, viruses, mold, non-oil based mists, and other particles you want to avoid. 3M's Cool Flow™ Valve releases exhaled breath quickly and effectively for temperatures inside the facepiece averaging 7.5°F cooler than similar masks tested without the valve. 3M's high-performance Electret filter media also makes breathing cooler and easier.  Package contains one (1) disposable mask.

NIOSH N100 approval rating signifies that the mask filters at least 99.97% of non-oil based particles as small as 0.3 microns. The "N" means it is not oil resistant. "N100" means highest NIOSH filtration rating in this class.


  • Disposable, valved respirator mask carries NIOSH's highest N100 rating for non-oil based particle filtration
  • Best choice for extended wear in hot, dusty or physically demanding conditions
  • Can be worn comfortably for longer periods than unvalved respirators, including the 3M 9210 N95
  • Cool Flow™ Valve means your face stays 7.5°F cooler and eyewear doesn't fog
  • Advanced 3M media filters out small particles and improves breathability
  • Adjustable dual head straps and foam faceseal ensure comfort and fit
  • Pliant nose foam and adjustable nosepiece form a secure seal
  • Lightweight and cool for increased wearability
  • Soft inner material adds comfort
  • Latex free
