While the CDC states, "any mask is better than no mask," you want to wear the most protective mask you can. You also want to know for sure what you are wearing. A false sense of security could put you in a situation where you unknowingly expose yourself or others to COVID-19.

Unfortunately, 60% of the KN95 masks that the National Institute for Occupational Safety and Health evaluated in 2020 and 2021 were deemed counterfeits. To protect yourself, you must learn to recognize red flags when buying these items.

A KN95 mask covers the mouth and nose. It has two elastic ear loops so you can secure the mask to your face. A KN95 mask filters out 95% of particles as small as 0.3 microns. For comparison, human hair is roughly 70 microns wide. While SARS-CoV-2 particles are smaller, the virus bonds to something larger, such as water droplets or aerosols. These items are larger than 1 micron, making the KN95 effective at reducing your chance of becoming infected by SARS-CoV-2.

A counterfeit KN95 mask may allow particles much larger than 0.3 microns to pass through the material. If this is the case, aerosol droplets that carry the SARS-CoV-2 virus can infect the wearer.

While it might be tough to distinguish an expertly copied mask from an authentic one, there are a few key red flags that tell when you should be wary.
