kn95 vs N95


What is kn95 mask?


KN95 is china standard according to GB2626-2019. "KN" means used to protect non oily particles (such as virus, bacteria, dust, etc.); "95" means that the filtering efficiency of the mask is ≥ 95% under the detection conditions specified in the standard. Kn95 mask can effectively protect particles suspended in the air.

Before 2020, KN95 non-medical mask is according to china standard GB2626-2006. At July 1st, 2020, China government update the standard of KN 95 to GB2626-2019.


What is N95 mask?


N95 masks are particulate protective masks certified by NIOSH (National Institute for Occupational Safety and Health). The filtration efficiency of particles with a physical diameter of 0.075±0.020µm reaches more than 95%, effectively resisting bacteria, viruses, dust, etc. N95 masks use high-standard water electret meltblown fabric, the biggest feature is to prevent the spread of droplets which caused by the patient's body fluids or blood splashes.

(2) Leaking rate

China government requires mask factory to manufacture kn95 mask with ≤8% leakage while n95 mask standard does not have this requirement.


This does not mean that leakage tests aren’t helpful. Many hospitals and companies have their own standard to test kn95 or n95 mask, not GB2626-2019 or Niosh standard.


★What is leakage: The leakage rate of the mask refers to the inhalation of particulate matter in the ambient air after the user wears the mask and performs the specified action under specified conditions.


(3) Inhalation and exhalation resistance

Kn95 vs N95 masks, the latter has higher requirements for pressure drop while inhaling and exhaling. That is to say n95 mask is more breathable than kn95 masks.


No worries. Although it is sometimes difficult to breathe when you wear a kn95 or n95 mask, there is a small chance of dying from hypoxia while wearing a mask. The government issued standards have been repeatedly tested and the damage to human body can be negligible.


(4) Usage Scenarios

When kn95 mask vs n95, kn95 masks are more suitable for use in high-density public places, such as shopping mall, KTV, bar, chess and poker room...

N95 masks are tended to be used for doctors and nurses, because n95 mask has function of blocking blood blood and body fluid splashes, which can better protect the safety of medical staff themselves

Similarities between kn95 and n95?


(1) Structure

kn95 adopts 5-layer structure design, 2 layers non woven fabric, 2 layers melt blown fabric and 1 layer of hot air cotton. N95 uses same design as kn95 mask. However, they still have a slight difference. Due to the different requirements of mask factories & customers, the gram of each layer can be changed. AnDum kn95 mask is as follows, 70g outer layer non woven fabric, 30g hot air cotton, two layers 25g melt blown fabric, 28g inner non woven fabric.


(2) Filtration

GB2626 2019 certified kn95 requires particulate filtration efficiency (PFE) over 95%, Niosh 42CFR84 certificated n95 requires PFE ≥95%. Higher filtration efficiency effectively protects our breath away from dust, pollen, saliva, etc.
