The difference between KN95 and N95 masks?

ByMike Hall

Due to the similarity of their names, it may be difficult for you to tell N95 from KN95 masks. What’s the difference between N95/KN95 masks? This article will discuss the similarities and differences in N95 and KN95 masks.

3M estimates that China’s KN95s are equivalent in value to the US N95s. 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 KN95 and N95?

Many are concerned about how much particles masks can capture. These are the same metrics for N95 and KN95 mask made in USA. Both masks capture particles as small as 95% (0.33 microns).

The N95/KN95 masks can capture 95% of the tiny 0.3-micron particles. Many people mistakenly believe masks can capture particles smaller that 0.33 millimetres. If this were true, it would be absurd for masks to prevent virus transmission. It is possible to capture particles smaller than 0.3 microns.

There is a distinction between N95 and N95 masks

To meet both ratings, masks must be tested for salt particle filter efficiency (NaCl). Both masks were tested at 85 L/minute. These are the main differences between KN95 and N95.

KN95 vs. N95 – Differences Highlighted

  • These differences aren’t significant, so they are not of interest to most users. These are the main differences.
  • China requires manufacturers to pass a mold-fit testing with real people. Fit tests are not required for N95 mask standards.
  • But this doesn’t mean they aren’t useful. Fit-testing is required by many hospitals and companies. These requirements apply to the company and not the US certification.
  • N95 masks require slightly higher pressure for inhalation. These masks are slightly more breathable than KN95 masks.
  • It is unlikely that you will be a zombie due to oxygen starvation.
  • The N95s have higher requirements for pressure drop during inhalation. This should improve breathability.

Bottom line: N95 and N95 masks are very different

The particle capture rate for both N95s as well as KN95s is 95%. Fit testing is not required for KN95 masks. KN95 masks can be used to protect you from viruses.
