Reusable respirator - Half-mask
--
The 3M(TM) 6291 (Medium) Half-Mask Respirator Kit includes the 3M(TM) 6200 Half-Mask Respirator and the 3M(TM) 2091 Particulate Filter. It helps provide respiratory protection in environments containing certain oil-based and oil-free particles.
The P100 2091 3MMC Particulate Filter provides respiratory protection against exposure to lead, asbestos, cadmium, arsenic and MDA. The filter is effective at concentrations up to 10 times the permissible exposure limit with half-facepiece respirators, or up to 50 times the permissible exposure limit with full-facepiece respirators that have undergone quantitative adjustment testing. This filter protects against a wide range of oil-based and oil-free particulate contaminants. 3M's advanced electrostatic filter provides a combination of comfort and lightness without restricting breathing. 3MTM Particle Filter 2091 is commonly used for welding, brazing, flame cutting, metal casting and soldering. This filter is both flame-retardant and water-repellent. Industries in which this filter is commonly used include agriculture, construction, general manufacturing, pharmaceuticals and primary metals.
- NIOSH-approved against certain oil-based and oil-free particles
- Its compatibility with bayonet restraints means it can be used with many models of 3M? half-mask and full-mask respirators.
- Advanced electrostatic filter provides a combination of comfort and lightness without restricting breathing
Choosing an N95 or P100 respirator?
N95 masks protect against 95% of airborne particles. 3M's P100 mask has a 99.97% leakage rate and offers the highest level of virtually airtight protection.
Respirator Rating Letter Class
Respirator Rating Number Class
-
95 - Filters out 95% of particles with a diameter of at least 0.3 microns
-
100 - Filters out 100% of particles with a diameter of at least 0.3 microns
3M™ Particulate Filter 2091, P100 helps provide respiratory protection against exposure to lead, asbestos, cadmium, arsenic, and MDA. The filter is effective for concentrations up to 10 times the Permissible Exposure Limit (PEL) with half facepieces, or 50 times PEL with quantitatively fit tested full facepieces. This filter helps protect against a wide range of oil and non-oil based particulate contaminants. 3M's Advanced Electret Media (AEM) provides a comfortable lightweight, easy-breathing combination. The 3M™ Particulate Filter 2091 is commonly used for welding, brazing, torch cutting, metal pouring and soldering. The filter is both flame and water resistant. Industries where this filter is commonly used include agriculture, construction, general manufacturing, pharmaceuticals and primary metals.
- NIOSH approved for environments containing certain oil and non-oil-based particles
- Bayonet compatibility allows use with many 3M™ Half and Full Facepiece Designs
- Advanced Electret Media (AEM) provides lightweight, easy breathing comfort
P100 is the highest grade for particulate filtering. The "95" refers to the percentage of gunk these masks can protect you from. N100 and P100 masks are therefore even more effective.
