KF94: Korean standard, which means that the filtration rate of particles with an average diameter of 0.4 μm is greater than 94%.

 

N95: American standard, which means that the mask filters more than 95% of non-oily particles with a diameter of 0.3 μm.

 

Comparison: The two standards are different. The US data comes from the National Institute of Occupational Safety and Health (NIOSH), and the Korean data refers to its Food and Drug Administration (MFDS).

 

 

【Protective ability】

 

KF94: can filter out at least 94% of particles with a diameter of 0.4 μm, and both oily and non-oily particles can reach the same level. No anti-spatter ability and bacterial filtration ability are required.

 

N95: Can filter out at least 95% of particles with a diameter of 0.3 μm, only non-oily particles. Spatter protection and bacterial filtration capabilities are also not required.

 

Contrast: In comparison, N95 filter particles are better (filter diameter and filtration rate are better than KF94), but KF94 has more requirements for oily particle filtration than N95. In addition, both of the non-medical masks have no requirements for bacterial filtration efficiency and splash resistance, so they are not as effective as the dedicated medical series.

 

【to sum up】

 

Through the comparison of the above three links, we probably know that compared to ordinary medical care masks, N95 and KF94 masks have better protection performance, and they can give everyone a certain degree of personal protection in daily travel. effect.

 

If you want to give a conclusion: no matter from the perspective of protection ability or economic benefits, it should be more cost-effective to buy masks of the N95 series.

 

But returning to the scenario mentioned at the beginning of the article, today when all types of masks are out of stock, Dr. Wu suggests that whether it is N95 or KF94, you can wear whichever you can buy.

 

The above is the introduction of the relative comparison between N95 and KF94, I hope to help you.
