It is important to understand that requirements for KN95 certification are the same as US N95 filtering facepiece respirators. That is why both KN95 and N95 provide the same protection level by international standards and certifications .
The Chinese government regulates KN95 medical masks under regulations GB2626-2006, GB262-2019, and GB19083-2010. The mask is usually available to older people in April 2020 to help the Chinese people and other countries fight the COVID-19 epidemic. The KN95 filtering facepiece respirator is also used by healthcare professionals, as the FDA rules and international standards approved the mask.
When it comes to the KN95 mask, it is designed to fit snugly around the face due to its ability to create airtight seals. This mask features an ear loop as a type of wear, unlike other types of masks that use headband attachments that go either behind the ears or behind the neck. When it comes to public opinion, many favor the KN95 mask design, as the mask can be put on quickly and easily, and it fits very well in the area from the nose to the chin (to prevent particles from entering the nose and mouth).
What KN95 mask protects you from?
The KN95 mask is believed to provide effective respiratory protection against all types of particles, including bacteria and viruses. The KN95 medical mask also offers 95% protection against all particles larger than 0.3 µm in diameter. This means that the mask helps you reduce the risk of bacteria, viruses, pollutants, particulate matter, dust, fog, and pollen.
The KN95 medical mask is a multi-layer mask, usually with 5-layer protection. The parts are made from high-quality, nonwoven fabric, warm air cotton, and melted blown fabric.
How long can you use the KN95 mask?
Both US N95 and Chinese KN95 masks are manufactured and designed for one-time use. This means that a new mask will be needed for each new use. However, due to the shortage of N95 and KN95 masks, the CDC has recommended the reuse of disposable filtering facepiece respirators as an emergency capability strategy. Strategies for the extensive use of masks such as N95 or KN95 are available at the National Institute for Occupational Safety and Health.
According to NIOSH, masks such as N95 and KN95 can be reused only if used properly and used by only one person. They can be used for extended periods of time, meaning that they can continue to wear the same mask. A period of one day, after which the mask should be removed due to frequent contact and close contact).
Experts emphasize that, unlike cloth masks, both N95s and KN95 require fit-testing. But as long as the respirator is properly connected, there is little reason to worry about choosing N95 versus N95.
