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.
