Which KN95 Masks Are Approved?

In the last few weeks, the US stance on imported respiratory facemasks has changed. To ensure medical staff have the equipment they need to combat Covid-19, Chinese manufactured masks will now be permitted. This policy reversal primarily refers to the KN95 mask, a facemask with near identical properties to the American N95 mask.

Despite the reversal, there are still questions being asked about the KN95 facemask and its ability to protect medical workers. To reiterate, the FDA has deemed these masks suitable and safe for use in the absence of normal N95 supplies. While KN95 masks reportedly fit looser, the lowest protection rating they have received is 89.9%.

This is still miles ahead of a surgical facemask made from paper. So, the FDA is recommending doctors and nurses switch to KN95 masks once their regular supplies are depleted. Let’s take a closer look at what this means for hospitals.

Can Facemasks from Overseas Be Trusted?

The FDA should be your guide on this whether you’re a hospital worker or a citizen who’s worried about catching the virus. If the FDA has approved a foreign made facemask, it has done so because it believes the item to be safe and reliable. This is the case for KN95 facemasks from China though they are not NIOSH approved.

It also includes non-NIOSH approved respiratory masks imported from Australia, Brazil, Korea, Japan, Mexico and most of Europe. All are suitable for use in American hospitals provided the products have been tested and approved ‘in country’ to a similar standard outlined by NOISH. These countries must be able to demonstrate adherence to equivalent standards.

Due to the unprecedented nature of the Covid-19 outbreak, KN95 facemasks and other imported supplies may be acquired without an EUA (for the time being). Where this is the case, importers are asked to take steps to validate the legitimacy of supplies. Where appropriate, the FDA is expediting imports of protective equipment, however, quality control checks are ongoing.

Importers are asked to use the following contact address to ensure requests and concerns are handled as promptly as possible:

Is It Safe to Use Expired KN95 Facemasks?

In normal circumstances, this would not be permitted. However, the FDA has determined expired facemasks (of an appropriate standard) do still provide sufficient protective in most cases. Regardless, this option should be viewed as a last resort. If imported supplies are expired, the manufacturer must make this clear at the point of sale.

The buyer must rigorously inspect the expired supplies before distribution and use. Any facemask with tears, holes or degraded material must be discarded or used for training purposes only.

The expiry date for a KN95 mask can be found on its label. If, for any reason, this is not the case, the manufacturer must provide accurate information.

The Final Word On KN95 Facemasks

The list of approved KN95 facemasks featured in this article is not exhaustive. For a comprehensive list, consult the FDA website. If the FDA has not approved a particular facemask, it should not be used in a medical setting. Currently, the guideline is for medical staff to continue using their regular N95 supplies and only switch to KN95 if these stocks become depleted.

The reuse of N95 and KN95 respiratory masks is permitted provided they are rigorously sterilized between uses. You are strongly advised to limit reuse to five occasions.


How kn95 mask works

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.


what are kn95 masks?

COVID-19 has spread around the globe, leaving many wondering how to best protect themselves and others. While it is commonly understood that wearing a mask benefits everyone in a public setting, there are several different types to choose from. The KN95 masks are currently recommended for Americans.

How To Properly Wear A Mask

Masks help protect contamination from spreading so that the person who is wearing a mask does not spread potentially infectious germs. By wearing a mask, it is less likely the individual will be able to touch their face, furthering the possibility of viral spread.

To properly use a mask, follow these steps:

-First make sure both hands have been scrubbed with soap and water for at least thirty seconds.

-The mask should stretch over the mouth, nose and chin.

-There should be no air gaps along the sides of the mask.

-If the mask should become damp, replace it immediately. Single-use masks are not beneficial after one wear.

Wearing a mask is advised in many situations. If you are visiting a doctor or medical setting, wearing a mask is advised. Health care workers or those taking care of someone sick at home should also wear a mask. Crowded public areas where it may be difficult to stand six feet apart are also situations where masks can greatly reduce viral exposure.

What Is A KN95 Mask?

N95 masks filter at least 95 percent of most particles and are frequently worn in hospitals. KN95 masks are recommended for the public and as a backup if N95s are not available in medical settings.

Respiratory face masks are different than loose-fitting masks. KN95 blocks at least 95% of airborne particles and is manufactured with high-efficiency filtering material. Because they are high quality masks that are approved by Chinese health standards, these masks are a suitable alternative when N95 masks are not easily available.

The KN95 mask and the N95 mask are almost the same. While they both protect the population from spreading airborne illness, the KN95 does require a mask fit test for some people. The vast majority of people can wear a KN95 mask inside or outside of a medical setting.

Should Healthy People Wear A Mask?

COVID-19 can affect anyone of any age. Since symptoms do not always occur right away, the spread of contamination is likely if proper precautions are not taken. Even if an individual has been tested and knows they do not have the coronavirus, wearing a mask is recommended when in public places where human contact may be difficult to avoid.

Homemade masks made from fabric or scarves are better than wearing nothing at all, but surgical masks will help the most. Surgical masks are helpful when reducing contamination that happens particularly during the springtime. With allergies and pollen, sneezing and coughing are more likely. To avoid droplets from spreading to others, masks can prevent allergies from becoming potentially dangerous to others.

Socializing with KN95 Masks

Since many people crave social contact, especially since the COVID-19 virus, it can be tempting to stand near someone for much-needed conversation. Even when standing several feet away from someone, germs can be spread through talking. While standing at least six feet away is still advised, wearing a mask can cut down on the possibility of spreading contamination through talking.

Coughing and sneezing are obvious ways that viral infections from fluid droplets can be spread in a relatively quick period of time. Talking and even breathing near someone can also be a mode for emitting fluid particles. Airborne illnesses are spread through cold-like symptoms as well as regular interaction. Wearing a mask that snugly covers both nose and mouth is one way to stop the spread of potentially dangerous airborne contamination.


KN95 masks are designed for public safety. Wearing these masks in the correct way can help reduce the spread of contamination. In areas where it is difficult to stay a safe distance apart from one another, these masks can greatly help in situations where food shopping or visiting a loved one is needed. Even in healthcare situations, KN95 masks are recommended when N95’s are not available. Their efficacy in slowing the spread of COVID-19 is well known.


how to clean KN95 Mask

When it comes to challenging times during the global coronavirus pandemic, people everywhere are protecting themselves. The CDC recommends wearing face coverings in public settings like grocery stores and pharmacies where other social distancing measures are difficult maintaining. That’s where the KN95 mask comes into play. Regulated by the Chinese government, the protective masks are almost identical in performance to N95 masks that hospitals in the United States have been rapidly running out of. Most importantly is knowing KN95 how to clean this mask to maintain its excellent performance as a filtering facepiece respirator against highly contagious COVID-19.

Superb Performance

Not only are healthcare workers on the front lines wearing the KN95 mask but people who are also sheltering in place and those employed in essential businesses. The protective mask has been given the green light by the Food & Drug Administration (FDA) as an excellent alternative to the N95 mask.

Both masks are exceptional at blocking at least 95 percent of airborne particles at 0.3 microns. The KN95 and N95 are manufactured with high-efficiency filter materials.

Avoid Washing Mask

When it comes to a high-performance face mask like the personal protective equipment or PPE, it has been designed to protect the wearer from airborne particles and liquid contaminating the face.

The last thing you want to do is destroy the PPE’s protective capabilities with improper cleaning because you will cause the disintegration of the mask’s material.

Do not wash your KN95 mask in soapy water. The mask is constructed of a unique paper outer and inner layer.

Rubbing alcohol and bleach immersion has also been shown to be ineffective at sanitization.

Remember to never share your protective mask with another person. The CDC advises that KN95 and N95 masks should be properly labeled and stored in their own containers between uses to maintain their cleanliness and avoidance of any damage or deformity.

Sanitizing Your Mask

In a perfect world, the KN95 and N95 masks would ideally be worn for a single-use and then tossed away, but during the coronavirus pandemic, it is impossible to have access to an unlimited supply of this effective PPE. Therefore, experts in the medical field have found ways of sanitizing these masks so that they can be reused and stored properly in the meantime.

One such medical professional on the front lines is Dr. Margarita David from She’s also a well-respected clinical professor with advice on cleaning these masks at her popular YouTube channel.

Dr. Margarita wears a pair of disposable gloves during the process:

  1. Lightly spray Lysol liquid disinfectant into the face mask and on the outside of the mask.
  2. Allow it to sit for 6 minutes to wipe out any microbes that have accumulated.
  3. When the time’s up, take a clean paper towel, and wipe the mask down.
  4. Then, store the mask in a small, clean, plastic container.

Second Sanitizing Technique

The oven method is another way of sanitizing your KN95 mask. Dr. Margarita also shared this process on YouTube:

  1. Preheat the oven to 160 degrees Fahrenheit. Allow it to stabilize at that temperature for a few minutes.
  2. Next, place your face mask on the top rack of the oven, and keep it in there for 30 minutes.
  3. Then, remove it from the oven. Your KN95 mask is intact, fully functional, and the coronavirus, if it were on the mask, has been inactivated by the heat and ready for re-use.

People everywhere want to be safe whether it’s on the front lines as medical professionals, working at essential jobs or walking around in public places. That is why a proper face mask like the KN95 is helping everyone dealing with the global pandemic. It is a mask that truly fits the contours of every adult face and offers very good blockage against at least 95 percent of airborne particles at 0.3 microns. The most important step is maintaining the efficiency of your protective mask with the right sanitization. By following the two methods outlined above on KN95 how to clean, your mask will be ready for re-use.


The Top Best Methods for Washing Kn95 Masks

Kn95 is a filtering facepiece respirator designed to protect people from hazardous bacteria and viruses. It is approved in China as one of the facemasks used amid the COVID-19 pandemic. Apparently, due to the crisis, Kn95 is in limited supply. Fortunately, some guidelines dictate how to use and clean these facemasks for safety. However, to prevent the escalation of coronavirus effects, health practitioners recommend total discard and replacement of Kn95 or any other personal protective equipment. Cleaning a Kn95 facemask is a good option, mainly due to their urgent demands. However, before doing any cleaning on your protective gear, you should scrutinize the type of cleaning method to prevent the facemask from losing its quality, and eventually, its ability to prevent the entry of bacteria or viruses.

How to Wash Kn95

The method you intend to use to clean your Kn95 mask must pass the following tests before it is given the go-ahead:

Viral load: The method should have the ability to decontaminate the mask by destroying possible viral load in the mask.

Mask fit: Facemasks prevent up to 95% of harmful pathogens from finding their way into your body. They are made to properly fit on our faces to safeguard your mouth and noses. Cleaning might, however, loosen them, exposing you to danger. A suitable cleaning method is, therefore, necessary to maintain the quality of masks.

Mechanism Ability: Mechanism ability means the mask’s ability to prevent the entry of foreign harmful substances. Such mechanism includes filtration capacity and ionic charge needed to keep away unwanted materials. The cleaning method must not interfere with the mechanical abilities of the mask.

Exposure: The chosen cleaning method must not expose the mask to other external substances such as oil, soil, or any other elements with chemicals.

The following are ways and steps on how to wash your Kn95 facemask.

Cleaning Using Hydrogen Peroxide: Hydrogen peroxide is widely known as one of the best disinfectants and can be an excellent decontaminator for Kn95 masks. A small amount of vaporized hydrogen peroxide is enough to efficiently clean facemasks. Studies have proven that 3% of hydrogen peroxide is enough to kill pathogens.

The main reason why hydrogen peroxide is the most preferred sterilizer is that it penetrates through the fabric-made Kn95 mask and destroys any remaining pathogen while maintaining the original ability of the facemask to prevent harmful pathogens from finding their way. This method, however, is still not employed by many health care institutions.

Deep the kn95 facemask in a hydrogen peroxide solution for some time; this is all you need to do to make your Kn95 facemask safe.

Cleaning Kn95 Masks Using Heat: A good number of organisms find it hard to survive in extreme temperatures, be it too cold or too hot, and bacteria and viruses are not exceptions. Subjecting pathogens to excessively high temperatures make them inactive. Heating the mask at the defined temperature also maintains its ability to prevent infections.

Heat your Kn95 mask for about 75 degrees Celsius for about 20 minutes, and all the damaging pathogens will be gone.

Using UV-light to Clean Kn95: UV-light is one of the contemporary ways of destroying viruses and bacteria. Studies have also revealed that they have the power to eliminate coronavirus. Just like other methods of cleaning Kn95 masks, the UV-light makes pathogens inactive.

You should concentrate UV-light on the Kn95 facemask to kill any foreign viral component.

Using Water and Soap to Clean Kn95: You can clean the mask using clean hot water and soap. To do this;

  • Deep your Kn95 mask in clean, warm water with detergent.
  • Gently rinse the mask.
  • Remove after a few minutes and put it in a drier.

Note that most masks should only be used once before discarding. However, with the limited supply, especially amid the COVID-19 pandemic, you can reuse the mask but ensure that it is not exposing you to the pathogens. The masks have different periods of use. There are the single-use, masks that are meant for one purpose and a specified period. The extended use masks, on the other hand, can be used for an extended period, especially during the current crisis. The best reuse method is to wash the Kn95 facemask before reuse. Nonetheless, you have to follow specified cleaning methods to ensure that you get rid of all the dirt and germs before getting the mask back on your face.
