  5. How Do KN95 Masks Protect from Coronavirus?

Wearing masks has become as controversial as it is practical, and it’s an extremely practical thing to do during a pandemic of a respiratory virus.  However there are many different kinds of masks on the market, with some more effective than others.  It’s important to understand how they work to know why you should be wearing one as we work to fight COVID-19.

N95 and KN95

Two oft heard recommended masks are the N95 and the KN95.  N95 and KN95 masks are very similar, with the primary difference being that N95 masks meet the United States standard for respirator masks and KN95 masks meet Chinese standards.  They are approximately equivalent however.  The ‘95’ in the name quantifies the protection they provide, which is 95% protection against all particles that are greater than 0.3 micrometers in diameter.  This includes-

  • Bacteria
  • Viruses
  • Pollution particles
  • Dust
  • Smog
  • Pollen

Layering System

Both N95 and KN95 are approved by the World Health Organization (WHO) for protection against COVID-19.  This is because of the multiple layers within the mask that work to trap and eliminate particulates in the air.

  • First layer- non-woven fabrics that are breathable and filter out larger particles
  • Second layer- melt blown fabrics which filter out smaller particles
  • Third layer- another layer of melt blown fabrics for dual protection
  • Fourth layer- non-woven fabrics that are soft and won’t irritate the skin

Other Benefits

In addition to not irritating the skin they also feel comfortable.  They are lightweight and built to adapt to the shape of the wearer’s face.  KN95 masks can also be worn in addition to other personal protective equipment (PPE) such as glasses, goggles, and ear muffs.
