Is there a difference between KN95 masks and N95 masks?

Due to the similar names, it may be hard to tell N95 and KN95 masks apart. What are the differences between N95 and KN95 masks? This article will discuss the similarities and differences among N95/KN95 masks.

3M estimates that China’s KN95s are worth the same as the N95s in the USA. Similar mask standards are also available in Australia (P2) and Europe (FFP2) as well as Korea (DS) and Japan (DS).


What is the difference between N95 and KN95?

Many are concerned about how many particles masks trap. These measurements are applicable to both the N95 or KN95 mask made in USA. Both masks can capture particles as small as 95% (0.33 microns).

The N95/KN95 masks can capture 95% of the tiny 0.3 micron particles. Many believe masks can capture particles smaller that 0.33 millimetres.


The distinction between N95 & N95 masks

To meet the requirements of both ratings, masks must be tested for salt particle filter efficiency (NaCl). Both masks were tested at 85 Liters per Minute.



KN95 vs. N95 - Differences Highlighted

  • These differences aren't significant so they are of little use to most users. These are the main differences.
  • China requires manufacturers to pass mold-fitting testing. N95 mask standards do not require fit tests.
  • But that doesn't mean they aren’t valuable. Fit-testing is a requirement in many hospitals and businesses.
  • N95 masks require slightly higher pressure to inhale. These masks are slightly more breathable than KN95 masks.
  • It is unlikely that you will become a zombie due to oxygen starvation.
  • For inhalation, N95s need a higher pressure drop. This will increase the breathability.

The bottom line: N95 andN95 masks are very distinct

Both KN95s and N95s have a 95% rate of particle capture. KN95 masks do not require fit testing. KN95 masks can protect you from viruses.
