There are two major categories of respirators:
- Air Purifying Respirators. These types of respirators include: - Air Purifying Disposable Particulate Masks; - Air Purifying Half Mask Respirators;
- Supplied Air Respirators. These types of respirators include: - Airline Respirators; - Emergency Escape Breathing Apparatus; and.
An N95 mask or N95 respirator is a particulate-filtering facepiece respirator that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 classification of air filtration, meaning that it filters at least 95% of airborne particles.
The P95 has a 40 hour or 30 day service life (whichever comes first). You can read more about this in the following NIOSH article: NIOSH-Approved Particulate Filtering Facepiece Respirators.
Once the filter is opened, it should compulsorily be changed within 6 months even if it is not used. Even when the cartridge filter is not in use, if it is open, it will keep on absorbing contaminants from the environment. If the filter is not opened and is safely stored, they have a shelf life of up to 5 years.
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. P95 – Filters at least 95% of airborne particles.
I have a 1/2 mask 3M 7500 respirator and am looking for organic vapor cartridges. 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.
N100 – Filters at least 99.97% of airborne particles. P99 – Filters at least 99% of airborne particles. Strongly resistant to oil. P100 – Filters at least 99.97% of airborne particles.
If used in environments containing only oil aerosols, replace filters after 40 hours of use or 30 days, whichever is first.
PAPRs' inherently higher filtration efficiencies (versus N95 masks) provide the best protection. More importantly, they can lead to improved compliance versus N95s. N95 compliance is confounded by high percentages of HCWs not passing fit testing.
Typically, a ventilator is a a device used to maintain artificial breathing or circulate fresh air, while a respirator is a mask used to protect the wearer from particulates in the air.
N95 Respirators. An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. The 'N95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles.
The 3M 2091 P100 (HEPA) Filter is sold by the pair and features extremely fine filtration that traps all but the most minuscule particles. HEPA filtration is rated to remove 99.9% of particles . 3 microns and larger.
Absolutely not. You can smell molecules as small as a dozen atoms across. N95 masks are designed to filter out 95% of virus sized particles, they don't filter out most things the size of molecules.

The N95 respirator is the most common of the seven types of particulate filtering facepiece respirators. This product filters at least 95% of airborne particles but is not resistant to oil.Clean the respirator face piece (excluding the cartridges and filters) with either a pre-packaged respirator cleaning wipe or by immersing in warm cleaning solution, water temperature not to exceed 120° F, and scrub with soft brush until clean. Add neutral detergent if necessary.
3M™ 6291 P100 Reusable Respirator Mask - Medium Size, will help protect against inhalation of a hazardous atmosphere and certain airborne particles . The reusable half face respirator mask comes with a set of P100 filters, and is recommended for working around dust, molds, pets, garage or workshop.
This site provides a listing of NIOSH-approved particulate filtering facepiece respirators. This type of air-purifying respirators protects by filtering particles out of the air the user is breathing. Ninety-five percent is the minimal level of filtration that will be approved by NIOSH.
Each cartridge contains granulated charcoal that is treated to absorb organic vapors from the air passing through as you inhale. Used mainly to protect against solvents, such as those in oil-based paints. Others would include paint thinner, lacquer thinner, turpentine and fuel vapors.
For a specific respirator or respirators, enter the NIOSH TC approval number(s) separated with semi-colon; Each class of respirator must be entered separately. Format with approval code (13F, 13G, 14G, 19C, 21C, 23C or 84A), followed by a dash and the 3 or 4 numbers following.
Once the filter is opened, it should compulsorily be changed within 6 months even if it is not used. Even when the cartridge filter is not in use, if it is open, it will keep on absorbing contaminants from the environment. If the filter is not opened and is safely stored, they have a shelf life of up to 5 years.
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.)
The difference between an N95, N99 and N100 respirator is simply the filter's efficiency level (i.e. N95 = NOT Resistant to solids and liquids which contain oil and provides 95% efficiency). The higher the efficiency, the more particulates the respirator will filter out.
N95 respirators can be safely decontaminated without undermining functional integrity only two or three times, a government study showed.
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. Not resistant to oil. P95 – Filters at least 95% of airborne particles.
However, the good thing is that the CDC states N95 respirators “are capable of filtering out all types of particles, including bacteria and viruses.”
Why use a P2 face mask? (also called N95)
Disposable P2/N95 face masks (also known as P2/N95 respirators) are able to filter out very fine particles from the air when worn correctly, and so reduce the risk of airborne transmission of Q fever and other infectious diseases when working in potentially contaminated areas.N95 Respirators.

The 'N95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles.
