3M™ Particulate Respirator Mask 9211 N95 with Valve - 10 Pack, is the right choice when comfort due to extended wear is most important. Designed and rated for workers and occupational use, but equally useful at home, the disposable 9211 (N95) offers optimum comfort, value and convenience whether you're grinding metal, sanding plaster or just working in the yard. The NIOSH N95-rated∗ respirator reduces inhalation exposure from allergens, dust, bacteria, viruses, mold, non-oil based mists, and other fine 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. In fact, the 9211 (N95) was cooler than all other disposable respirators tested by 3M.  Box contains ten (10) individually packaged masks.

NIOSH N95 approval rating signifies that the mask filters at least 95% of non-oil based particles as small as 0.3 microns. The "N" means it is not oil resistant.

Do Not Use For:

Gases and vapors, oil aerosols, asbestos, or sandblasting; particulate concentrations that exceed either 10 times the occupational exposure limit or applicable government regulations, whichever is lower. In the U.S., do not use when OSHA substance-specific standards, such as those for arsenic, cadmium, lead in the construction industry, or 4,4’-methylene dianiline (MDA) specify other types of respiratory protection. This respirator does not supply oxygen.

Biological Particles:

This respirator can help reduce exposure to certain airborne biological particles (e.g., viruses, mold, Bacillus anthracis, Mycobacterium tuberculosis, etc.) but cannot eliminate the risk of contracting infection, illness or diseases. OSHA and other government agencies have not established safe exposure limits for these contaminants.
