N95 or UK FFP2 a particulate-filtering facepiece respirator that meets the U.S. National Institute for Occupational Safety and Health (NIOSH)


KN95 classification of air filtration meaning that it filters at least 95% of airborne particles.

another standard P95, adds that requirement.


The KN95 type is the most common particulate-filtering facepiece respirator.


It is an example of a mechanical filter respirator which provides protection against particulates but not against gases or vapors.


KN95 respirators are considered functionally equivalent to certain respirators regulated under non-U.S. jurisdictions such as FFP2.


Respirators of the European Union. However, slightly different criteria are used to certify their performance such as the filter efficiency test agent and flow rate, and permissible pressure drop.


The KN95 mask requires a fine mesh of synthetic polymer fibers, also known as nonwoven polypropylene fabric.


Which is produced through a process called melt blowing that forms the inner filtration layer that filters out hazardous particles


How to Wear the KN95 Mask

Always read and follow the manufacturer's directions when using an KN95 mask.


It must cover both the nose and mouth to keep you from breathing in mold and dust.


If it does not have a snug fit it will not work properly.


Correct fit of the mask requires contact with smooth skin.


It will not work properly for people with beards or facial hair.


Even one-day beard growth has been shown to let air leak in.


Always use both straps on the mask to hold it in place to keep air from leaking around it.


How to Make Sure the Mask Fits


Do a user seal check, including both positive and negative pressure checks, to verify that you have correctly put on the mask and adjusted it to fit properly.


Negative pressure check place both hands completely over the mask and inhale sharply.


Be careful not to disturb the position of the mask.


The mask should pull into your face.


If air leaks around your face or eyes adjust the nosepiece and straps and repeat the positive pressure check.


Positive pressure check


Put your hands over the mask and breathe out sharply.


If your mask has an exhalation valve  be sure to cover the exhalation valve when you exhale.


No air should leak out of the mask if it fits properly.


If air leaks out, re-adjust the nosepiece and straps and repeat the negative pressure check.


When to Throw Out the KN95 Mask


As the KN95 mask gets clogged it becomes more difficult to breathe.


When this occurs throw it out and use a new one.


Discard the mask if it is wet or dirty on the inside if it is deformed or if the filter is torn.


A deformed mask may not fit properly. An KN95 mask cannot be cleaned or disinfected.
