You may find it difficult to tell the difference between N95 or KN95 masks because they have similar names. What are KN95 Masks and how are they different from N95 masks. This article will help you explain the differences and similarities between N95 masks and KN95.
3M mask manufacturer says that China's KN95s are “equivalent” in value to US N95s. Very similar mask standards are available for Europe (FFP2) and Australia (P2) as well as Korea (KMOEL) and Japan (DS).
N95 and KN95: What is the Difference?
A lot of people care about how many particles the masks capture. These metrics are identical for N95 and KN95 mask made in USA. Both masks have a 95% efficiency in capturing tiny particles (0.3 microns).
Masks N95/KN95 are capable of capturing 95% of 0.3-micron particles. This is why people often mistakenly assume that they can't capture particles smaller than 0.3 millimetres. If this were true, it would be absurd to believe that masks can prevent virus transmission. It's quite simple to capture particles smaller than 0.3 microns.
Difference between KN95 and N95 Masks
Both ratings require that masks are tested for their filtration efficiency in capturing salt particles (NaCl). Both are tested at 85 L/minute. Here are some differences between KN95 & N95.
KN95 vs. N95 – Differences Highlighted
- The majority of these differences are minor and uninteresting for the average user. These are the main differences.
- China requires manufacturers to pass a special mold fit test using real humans. Fit tests are not required by the N95 mask standards.
- This does not mean that fit tests aren’t useful. Fit-testing is a requirement for many companies and hospitals. These are requirements for companies and not the US certification.
- N95 masks require a slightly higher pressure drop when inhaling. This means that they are slightly more breathable than KN95 masks.
- Despite it being difficult to breathe through masks, it is extremely unlikely that will die from oxygen starvation.
- N95s also have more stringent requirements regarding pressure drop during inhalation, which should aid with breath ability.
Bottom Line: There is a difference between N95 and KN95 masks
Both KN95s and N95s have a 95% particle capture rate. KN95 masks do not need to pass fit tests. KN95 mask are good to protect against virus.
