KN95 INFO

KN95 face masks filter out up to 95 percent of particles, droplets, bacteria and viruses from the air you breath that are 0.3 micron or larger in size. As the COVID-19 virus spreads and becomes more widespread among those around us, it is becoming more and more likely that the air we breath in may contain COVID-19 virus. Therefore, the simple act of taking a breath may infect you with COVID-19. However, if you wear a KN95 face mask each time you go out in public, the KN95 face mask will filter out up to 95 percent of the dangerous particles from the air that you are breathing in. If you purchase and wear our KN95 face masks, and wash your hands regularly, you will protect yourself as much as you possibly can!

According to the Centers for Disease Control (CDC) cloth face coverings are recommended as a simple barrier to help prevent respiratory droplets from traveling into the air and onto other people when the person wearing the cloth face covering coughs, sneezes, talks, or raises their voice. This is called source control. However, the cloth masks do nothing to protect YOU from COVID-19 each time you take a breath. A recent study by Duke University has shown that depending on the type of cloth that is used to make the cloth face mask, the cloth face masks sometimes spread the droplets more than wearing no cloth face mask at all. Duke University found that this is particularly true for neck gators. Further, cloth face masks do not protect the person who wears it from COVID-19 when the person inhales as the cloth is not able to filter out the dangerous droplets from the air they are breathing in. Therefore, while wearing a cloth mask may provide some limited degree of protection to those that are around you from the droplets that you are exhaling, the cloth mask does not protect you from COVID-19 each time you take a breath.

Face masks that are certified as meeting either the N95 or the KN95 standard mean that they will filter out at least 95 percent of all non-oil particles that are larger than 0.3 microns in diameter. The N95 face masks are certified to have met the American NIOSH standard for respirator face masks. The KN95 face masks are certified to have met the Chinese GB2626-2006 standard for respirator face masks. If one reviews the elements for each standard, it is evident that the N95 and the KN95 respirator face mask are equivalent or closely equivalent on most health related features. The following chart lists the features of each of the N95 and KN95 standards.

The American respirator face mask company, 3M, states that “it is reasonable to consider” China’s KN95s “equivalent” to the American N95 standard. The respirator face mask standards for Europe (FFP2), Australia (P2), Korea (KMOEL), and Japan (DS) are also similar to the KN95 and N95 standards in what they filter from the air you breath in. It is important to understand that the KN95 respirator face mask standard is equivalent to the American N95 standard in filtering the air as both masks filter out up to 95 percent of particles that are larger than 0.3 microns in diameter from the air you breathe. Remember that cloth masks that some people wear, do not protect the person who wears them and they only marginally protect those around the person who wears it. However, if you wear a KN95 or a N95 respirator face mask, it will filter the air each time you take a breath of air and help protect the wearer; unlike a cloth mask.

Air filtering face masks are subject to various regulatory standards and compliance guidelines from around the world. These guidelines and standards specify the required physical properties, performance characteristics and functionality necessary for achieving a particular face mask standard within a particular country. During emergency situations such as epidemics and pandemics, health authorities have authorize the use of certain foreign standards of face masks such as N95, KN95, or FFP2 equivalents. The most common face-piece respirator standards from across the globe are as follows:
  • N95/N99 – United States NIOSH
  • FFP2/FFP3 – Europe CE EN 149:2001+A1:2009
  • KN95 – China GB2626-2006
  • Special 1st – Korea KMOEL – 2017-64
  • P95 – Mexico NOM-116-2009
  • P2/P3 – Australia AS/NZS 1716:2012
  • DS/DL2/DL3 – Japan JMHLW-200
In the United States, the most commonly available and well-known face masks are the NIOSH approved N95 face masks which filter up to 95 percent of particles that one breathes and create an air tight seal around the face. FFP2 respirator masks are certified by the European Union to meet the standards of CE regulation EN 149:2001+A1:2009 for filtering up to 94 percent of particles. KN95 masks are regulated by the Chinese government under regulation GB2626-2006 and are rated to filter 95 percent of particles; the same as the American NIOSH approved N95 face mask standard. N95 and KN95 masks both filter up to 95 percent of particles and create an air tight seal around the face. Other differences between N95 masks and the KN95 masks is that KN95 masks often use the ear loop method to secure the mask to the face. The N95 masks use a two head-strap attachments, one that goes around the back of the head under the ears and another that goes on the top over the crown of the head above the ears. It really comes down to personal preference in terms of which one is more comfortable for the wearer as well as which type of face mask is available to use. If you want your family, and you, to be protected from the COVID-19 virus when you inhale, it is critical to wear a KN95, a N95 or a FFP2 face mask and not wear a simple cloth face mask. Remember, a cloth face mask only protects the person that is standing next to you. It does not protect you. The only way you are protected when you breathe is if you wear a KN95, a N95 or a FFP2 standard face mask.

According to the Mayo Clinic, “ . . . a cloth mask is intended to trap droplets that are released when the wearer talks, coughs or sneezes. Asking everyone to wear cloth masks can help reduce the spread of the virus by people who have COVID-19 but who don't realize it. Cloth face coverings are most likely to reduce the spread of the COVID-19 virus when they are widely used by people in public settings.” However, it is important to remember that cloth face masks do not protect the person who is wearing it. It only protects the people around you from the droplets that you release when you exhale or cough. The idea is that if everyone is wearing a cloth face mask, then everyone in the group will be protected. However, we know that many people are refusing to wear face masks. Therefore, while you may be protecting others when you wear a cloth face mask, you have no protection for yourself when you take a breath. You may be infecting yourself each time you inhale. The only way to protect yourself and your family from COVID-19 is to wear a face mask that filters out 95 percent of the airborne water particles that you breathe in from the air that surrounds you. The only face masks that filter out 95 percent of airborne particles are face masks that meet the American N95 standard or the Chinese KN95 standard. Unlike cloth face masks, our KN95 face masks are very effective at protecting you from the COVID-19 virus as they all filter out 95 percent of airborne particles each time you take a breath. Our KN95 face masks filter out up to 95 percent of all particles, droplets, bacteria and viruses, 0.3 micron in size, from the air your breath in.

John Hopkins Medical Center says that “according to the CDC, recent studies indicate a significant portion of people who have COVID-19 don’t show symptoms, and the virus can spread before they realize they are sick. This research, combined with the fact that the corona-virus can spread through close proximity to others, often by speaking, coughing or sneezing, led to their recommendation for the general public to wear cloth masks in public, especially in situations where physical distancing may be difficult, such as grocery stores or on public transportation, and in areas where there is a significant amount of community transmission.” Therefore, you should always wear a N95 or a KN95 face mask that protects you each time you take a breath from the COVID-19 virus. Cloth masks offer you little to no protection from the COVID-19 virus when you take a inhale or breath in.

The vent value in a face mask is a one way door that is designed to let hot moist air out of your face mask when you exhale but not let in any outside air when you breathe in. A face mask with a vent value is very useful if you wear glasses. The value vents the hot moist air out of your face mask when you exhale and minimizes the fogging on your glasses that often occurs when you wear a face mask. The vent value will also make wearing a face mask more pleasant as you don’t have the hot moist air around your face all the time. Of course, by venting your hot moist air out of your face mask when you exhale, if you have the COVID-19 virus, your face mask is not containing 100 percent of your particles within your mask when you exhale. This may put those around you at a higher risk of becoming infected when you exhale. Many of your moist particles will still be captured within your mask as you exhale but some will escape out of your mask through the vent valve. Therefore, one should consider when and where to wear a KN95 face mask with a vent valve. It is useful to have both a vented KN95 face mask and one without a vent valve so you can choose which one to use in appropriate situations.
