Who is NIOSH? The National Institute for Occupational Safety and Health (NIOSH) coordinates with the U.S. Centers for Disease Control and Prevention (CDC) to address national health needs associated with preventing the spread of swine flu and providing information to workers and employers.
What does N95 Mean? The N95 designation is an efficiency rating that means the mask blocks about 95% percent of particles that are 0.3 microns in size or larger.
What is a Micron? Normally particles greater than 5 microns fall out of the air. Particles 1 – 5 microns in diameter can enter upper airways 0.1 – 1 micron particles can enter lower lungs and alveolar ducts
Examples of particle size:
Viruses 0.02 to 0.3 microns
Bacteria 0.5 to 10 microns
Mold spores 1 to 70 microns
Fungi 2 to >200 microns
What’s so special about the N95 mask? Also known as a N95 Respirator. The N95 respirator masks are not regular surgical masks, surgical masks are loose fitting and porous and provide little protection against particles as small as viruses, according to the few trials that have been carried out. N95 masks are similar in appearance to surgical masks, but are designed to form a tight seal against the wearer’s skin. If fitted and worn properly, the masks block out at least 95% of virus particles.
Make sure it fits:
1. Cover front of respirator mask by cupping both hands.
2. Inhale sharply. A negative pressure should be felt inside respirator mask. If leakage is detected at respirator edges, adjust straps by pulling back along the sides and/or reposition respirator.
3. Repeat until mask is sealed properly.
4. User must be clean-shaven. Any facial hair, such as beards or long sideburns, may prevent the respirator from fitting properly. Entry into a contaminated area with an improper fit may result in sickness or death.
Types of masks descriptions:
N95 Filters at least 95% of airborne particles. Not resistant to oil.
N99 Filters at least 99% of airborne particles. Not resistant to oil.
N100 Filters at least 99.97% of airborne particles. Not resistant to oil.
R95 Filters at least 95% of airborne particles. Somewhat resistant to oil.
P95 Filters at least 95% of airborne particles. Strongly resistant to oil.
P100 Filters at least 99.97% of airborne particles. Strongly resistant to oil.
Contrary to popular belief, the brand name of the mask is not nearly as important as the rating. To help prevent the spread of the H1N1 Swine Flu, it is recommended by the Centers for Disease Control (CDC) that you use a mask with a rating of N95 or higher.

Swine flu is very dangerous disease. Its almost fatal. Like its is said, “Prevention Is Better Than Cure”, one should cover face with mask to protect from swine flu virus. The N-95 masks are popular. It is basically a surface for entrapment of the virus from outside, so one should wash the mask on a regular basis followed by washing one’s hands and face.

Because the contours of everyone’s face is different, it tends to vary as to how well an N95 Mask will fit your face. Some brands, such as the 3M N95 masks are availble in two sizes, but since they are non-returnable, if you purchase the wrong size you are stuck with them. Kimberly Clark N95 Respirator Face Masks are designed to fit faces of all shapes and sizes. The only drawback? When you wear it, you sort of look like a duck
