Recent weeks have seen the kn95 mask thrust into the spotlight as an alternative to the now-famous n95 respirator. With the coronavirus crisis taxing the American healthcare system and personal protective equipment suddenly hard to come by, hospitals and communities have had to look for new ways of acquiring crucial supplies. In the case of masks, the kn95 model, long the preferred respiratory in China, is being imported to supplement the dwindling stocks of the n95 mask typically favored in the United States. But what exactly are these masks, and how do they work?
What Is the kn95 Mask?
The kn95 mask, like the preferred n95 model, is a type of “filtering facepiece respirator” designed for use by medical professionals when extreme precaution is necessary. Many countries and regions around the world have their own variant of this essential protective equipment. But while the specifics might vary slightly, all filtering facepiece respirators serve the same function and operate in essentially the same way. Whereas the n95 mask is the United States’ preferred model, the kn95 mask is the Chinese version. Beyond the difference in origin and a few minor variations, they are basically the same thing.

How These Masks Work
The purpose of filtering facepiece respirators, the kn95 mask included, is to achieve as efficient a level of filtration as possible so that the wearer is protected from tiny airborne droplets and particles while still being able to breathe. While they cannot completely eliminate the chance of contamination, they reduce the passage of tiny particles by at least ninety-five percent. This is crucial in protecting healthcare workers from a disease like Covid-19, which is transmitted through airborne droplets.
In order to be effective, kn95 masks must be fitted correctly. They are meant to be worn very tightly, so that no air passes by the outside of the mask and into the user’s nose or mouth. The mask should make an impregnable seal around the nose and mouth. This need for tightness is so great that children and adults with facial hair cannot reliably use them. For a male healthcare worker during the coronavirus crisis, this means a regular shave is a necessity.
The kn95 mask is designed to act as a filter between the user and the outside air. They protect the user’s respiratory system not just from the aforementioned tiny particles, but also from microorganisms and body fluids. This makes them especially suited to healthcare settings.
Kn95 respirators, like their n95 counterparts, are meant to be disposable. This has become an issue during the coronavirus epidemic, as hospitals run low on personal protective equipment. Experts are seeking ways to sterilize and re-use this vital resource. Nonetheless, the FDA labels filtering facepiece respirators as disposables and meant for one-time use. They are supposed to be discarded once they are soiled or when it becomes exceptionally difficult for the user to breath through them.
Masks Can Cause Difficulty Breathing
Kn95 masks and similar respirators often make it a bit more difficult for users to breathe. While some variants have exhalation valves that cool the face and facilitate easier breathing, these models cannot be used in healthcare settings during the coronavirus crisis because they are not entirely sterile. When fear of contagion is as high as it is now, the normal, valveless models must be used, despite the restrictive breathing they cause. That is why the FDA recommends people suffering from asthma or other chronic illnesses affecting the respiratory system seek permission from their doctors before using a mask.
How They Differ From Regular Hospital Masks
Filtering Facepiece Respirators like the kn95 mask are more effective than regular surgical masks at blocking harmful particles. Surgical masks consist only of a simple piece of cloth stretched over the mouth and nose. These simpler masks can help prevent the spread of the virus, which is why they are recommended for the general population, but they are not as efficient as kn95 masks at filtering particles, which is why healthcare workers must be prioritized in the distribution of the better masks.
As the crisis continues, more kn95 masks will likely be in use around the country. Now, you know exactly how they work.
