The N95 is made by various manufacturers under different names, from MSA's "Affinity Foldable Respirator" to 3M's "Particulate Respirator." Look for "NIOSH N95" on the package; the "N95" is a government efficiency rating that means the mask blocks about 95 percent of particles that are 0.3 microns in size or larger.
These are filtering facepiece half-mask respirators, sometimes referred to as N95s. A filtering facepiece respirator covers the nose and mouth, and is a tight-fitting, air-purifying respirator in which the whole facepiece functions as the filter.
Choose a Cartridge and/or Filter
- Resistance to oily mists.
- Filtration efficiency.
- Organic vapors from solvents, such as those in paints and thinners, require a cartridge with a black label.
- Cartridges approved for acid gases, include gasses such as chlorine, hydrogen sulfide and sulfur dioxide, have a white label.
A P100 rating is the highest for personal respiratory protection. As long as your mask fits properly a P100 filter will block 99.9% of particles . 3 microns or larger. (If you're interested in the nitty-gritty the CDC has a comprehensive and fairly unreadable guide to particulate respirators.)
3M 2091 P100 Particulate Filters replace the filters that come with the 3M 6291 P100 Reusable Respirator sold by National Allergy.
The 3M 6001 Organic Vapor Cartridge is NIOSH approved for a wide variety of organic vapors. Each cartridge contains granulated charcoal that is treated to absorb organic vapors from the air that passes through the cartridge as you inhale. It is used mainly to protect against solvents, such as those in oil based paints.
The 3M Daily Face Masks are washable and come in a resealable pouch that can be used to store your mask when not in use. These masks are not intended for medical use and do not eliminate the risk of contracting any disease or infection.
If cartridges are open or not packed in air-tight packaging, they should not be used. Even cartridges in original packaging have expiration dates that should be checked before purchase. Also, over time your mask can get old and break down. Keep your mask in a clean, dry place, away from extreme heat or cold.
As a general rule of thumb, filters can be used up to seven times. However, this will also depend on how often you wash your mask, as these filters cannot be cleaned.
As you notice strong odors that weren't there before, it's a sign that it's time to replace your cartridge. When replacing the 3M 60926 Multi-Gas P100 Cartridge, the charcoal-filled multi-gas cartridge and the P100 filter are locked together, so you will need to replace them both at the same time.
Store them as soon as they are dry so they don't collect dust. Store clean, dry respirators in nonporous, sturdy, airtight containers, like a zip-sealed plastic bag. Store cleaned respirators separate from cartridges. Store respirators in a cool, dry cabinet specifically designated for storage.
P3 dust mask offers higher protection than the P2 and P1 mask and is used in workplaces with a higher concentration of dust. Workers who handle hazardous powders like the ones that are used in the pharmaceutical industry generally use P3 masks.
This cartridge/filter can help reduce inhalation exposures to certain airborne biological particles (e.g., mold, Bacillus anthracis, Avian Influenza viruses, Mycobacterium tuberculosis, etc.), but cannot eliminate the risk of contracting infection, illness, or disease.
N95 – Filters at least 95% of airborne particles. Not resistant to oil. Surgical N95 – A NIOSH-approved N95 respirator that has also been cleared by the Food and Drug Administration (FDA) as a surgical mask. N99 – Filters at least 99% of airborne particles.

Please visit our Service Life Software and use the table for surrogates for the TR-600 and TR-800 PAPR System cartridges. Cartridges must be changed earlier if contaminant taste, odor or irritation is detected by the user, or system alarms indicate filter loading.
If the filter is not opened and is safely stored, they have a shelf life of up to 5 years.

They do not protect against hazardous dusts, gases, or vapors. What is a respirator? A respirator is a NIOSH approved device designed to protect the wearer from inhaling hazardous dusts, fumes, vapors, or gases. An N95 is one type of respirator that protects the wearer from inhaling hazardous dusts.
PM2. 5 is an ISO standard referring to tiny airborne particulate matter that are the less than 2.5 microns (0.0025mm) wide – or 3% the size of human hair. A PM2. 5 filter is designed to filter airborne particulate matter smaller than 2.5 microns.

It probably goes without saying, but we'll say it anyway: You can't wash your cartridges. Next, hand wash the respirator facepiece in warm water. Use a disinfectant soap. Check with the manufacturer to see if there are recommended brands.
Respirator Selection Air-purifying vs.Atmosphere-supplying Respirators
- Particulate Respirators. Capture particles in the air, such as dusts, mists, and fumes.
- Combination Respirators. Are normally used in atmospheres that contain hazards of both particulates and gases.
- Gas & Vapor Respirators.
The many types of respirators available include (1) particulate respirators, which filter out airborne particles; (2) “gas masks,” which filter out chemicals and gases; (3) airline respirators, which use compressed air from a remote source; and (4) self-contained breathing apparatus, which include their own air supply.
Time Use Limitations1. If filters become damaged, soiled, or breathing becomes difficult, leave the contaminated area immediately and replace the filters. 2. If used in environments containing only oil aerosols, replace filters after 40 hours of use or 30 days, whichever is first.

Those smallest flu particles could squeeze their way through a respirator filter. Respirators are still a worthy line of defense, however, as a recent CDC study found that a properly-fitted N95 respirator mask blocks 99.6% of flu particles.
