N95 respirator masks are a type of protective outerwear used to filter out a wide variety of particles and pathogens from the air, at an efficiency of at least 95% for particle size greater than 0.3 micron. This includes particulates like dusts and microorganisms. P100 respirator filters are even more effective, filtering at least 99.97% of such particles - and some P100s can also help filter out nuisance levels of organic fumes, vapors and gases.

N95 respirator popularity has grown recently, with increased awareness of air pollution, and for their ability to filter out dangerous pathogens, including airborne bacteria and viruses.

3M N95 Mask Benefits and Uses


An N95 respirator is a protective device that fits closely on your face and has a very efficient filtration of airborne particles. N95 masks are far superior to cheaper loose fitting surgical masks in terms of their seal against the face, and their ability to filter out particles (their inward leakage).  


N95 face masks are sometimes called flu masks because they are effective at filtering a variety of airborne pathogens, including bacteria and some viruses. Note: N95 respirators are correctly referred to as respirators and not masks.


N95 respirators are highly effective at filtering human sneeze particles, which is the primary method of propagation for most airborne viruses, including the subgroup of coronaviridae viruses (which include the SARS-CoV-2 virus, and other viruses that cause the common cold, influenza, etc.)


Note that the percentage filter rate for airborne particles (read below) refers specifically to the mask’s ability to filter out all particles above 0.3 microns in size.

Further Information:


There are a number of ways that different respirators can be classified, depending on the region.


United States Classification:


N = Not oil resistant

R = Oil resistant

P = Oil Proof

N95 = Not oil-resistant, filters ≥ 95% of airborne particles.

R99 = Oil resistant, filters ≥ 99% of airborne particles.

P100 = Oil proof, filters ≥ 99.97% of airborne particles.


European Classification:


P1 = Filters ≥ 80% of airborne particles

P2 = Filters ≥ 94% of airborne particles

P3 = Filters ≥ 99.95% of airborne particles

FF1 = P1 = < 22% inward leakage

FF2 = P2 = < 8% inward leakage

FF3 = P3 = < 2% inward leakage


Korean Classification:


KF80 = Filters ≥ 80% of airborne particles

KF94 = Filters ≥ 94% of airborne particles

KF99 = Filters ≥ 99% of airborne particles


Scientific Consensus:


N95 facepiece respirators are effective at filtering out the a large percentage of potentially harmful particles. To work as intended, the facemask needs to fit your face correctly. A proper fit should be snug against the face with minimal areas left uncovered.


The FDA has cleared a number of N95 respirators for use by the public in case of a public health medical emergency. They have also cleared certain N95 respirators for use in industrial and healthcare settings.


The Centers for Disease Control and Prevention (CDC) does not generally recommend facemasks and respirators for use in-home or community settings, though this guidance may potentially change during epidemic periods, when use of masks or respirators may help slow community spread of infectious respiratory diseases, such as influenza or coronavirus-related diseases. Such diseases spread through exposure to the conjunctiva - eyes, nose and mouth - often via one's hands. Therefore, during outbreaks of respiratory disease, simple use of masks or respirators is not adequate to provide good protection, eye protection is also recommended, and frequent hand washing / use of alcohol based hand sanitizer throughout the course of the day when touching frequently touched objects is also an important aspect of risk reduction.




People with chronic respiratory, cardiac, or other medical conditions that make breathing difficult should check with their healthcare provider before using an N95 respirator because the N95 respirator can make it more difficult for the wearer to breathe.


If your respirator becomes damaged or soiled, or if breathing becomes difficult, you should remove the respirator, discard it according to proper technique, and replace it with a new one. For reusable respirators, you can clean the respirator and replace the filters, disposing of the old filters without disposing of the permanent respirator itself.

Note that while respirators are effective at filtering most particles > 0.3 microns in size, they cannot guarantee your safety in a public health emergency. In case of an emergency, pay close attention to public health instructions from the CDC or the relevant authority.
