Face masks have become an essential part of our dressing whenever we are going out since the Centers for Disease Control, and Prevention (CDC) recommended it in public spaces and also in private spaces shared with other people.
As we are waiting for an effective COVID-19 vaccine, we still have to follow the recommendation laid down by the CDC to avoid getting infected by COVI9 or spreading the virus further. So, people must wear face masks whenever they are in public spaces.
Nevertheless, when it comes to personal protective equipment (PPE), there are several options. The highest quality and highly demanded masks are the N95 or KN95 masks.
The KN95 and N95 face masks provide an intense protection level than other face masks sold in the market. Both N95 masks and KN95 masks are produced from multiple layers of synthetic material (polypropylene plastic polymer) and are carefully designed to be worn over the mouth and nose. They possess straps behind your ear that helps to hold the mask properly. They both filter out and capture 95% of tiny 0.3-micron particles in the air (that's why they have "95" in their names).
Written Below are the Differences Between N95 and KN95:
Normally, the N95s are regulated and certified by the National Institute for Occupational Safety and Health (NIOSH) in the U.S, while the Chinese government controls the KN95s.
Certified KN95s will perform similarly to N95s since they have a similar filtration rate. But the KN95s may have ear loops, while most N95s have head straps. And it's always easy to get the KN95s than the N95s since the demand for N95s keeps increasing daily.
KN95 face masks provide a looser fit than the N95 face masks. Although, the Chinese government demands that the KN95 face masks pass a fit test, with less than 8% leakage. However, the N95 face masks are not needed to pass a fit test by the NIOSH, but some companies may need them.
N95 face masks possess precise requirements when it comes to breathability. The pressure drop on inhalation must be less than 343 Pa and less than 245 Pa on exhalation. KN95 masks are required to possess an inhalation pressure drop of less than 350 Pa and an exhalation pressure drop of 250 Pa. This implies that N95 respirators are a little more breathable than the KN95 face masks.
