What is the difference between KN95 masks and N95 masks?

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 masks and KN95? This article will discuss the similarities and differences in N95 and KN95 masks.

According to 3M China's KN95s are equivalent in value to US N95s. Similar mask standards are also available in Australia (P2) and Europe (FFP2) as well as Korea (DS) and Japan (DS).

KN95 and N95: What is the Difference?

Many are concerned about how many particles masks can capture. These are the same metrics for KN95 Mask made in USA. Both masks capture microscopic particles at 95% (0.3 microns).

The N95/KN95 masks can capture 95% or more of the 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 difference 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 aren't of much interest to the average user. 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 valuable. 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.

Despite the fact that oxygen starvation can be fatal, it is unlikely you will go insane.

The N95s have higher requirements for pressure drop during inhalation. This should improve breathability.

Bottom line: Masks N95 and N95.

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.
