FFP2 mask analysis| KENJOY

There are a lot of different opinions about masks on the Internet. In order to protect yourself, it is necessary to have a clear understanding of FFP2 masks.

What is the meaning of the alphanumeric letters on FFP2 masks?

Letters stand for different national standards. The N series is the U.S. standard, the KN series is the Chinese standard, the FFP series is the European standard, and the KF series is the Korean standard. The number behind refers to the protection ability, the greater the protection level is also higher. The 90 series does not have the same level of protection as the 95, but it can resist more than 90 percent of the particles. In FFP series, 2 basically corresponds to 95, and 3 has a higher filtration efficiency of 99%. Numbers with a "V" at the end indicate a breathing valve.

What is the difference between medical and non-medical masks?

Masks such as N95 and KN95 are available in both medical and non-medical types. Masks with the "medical" mark can be used for front-line protection for medical workers, while masks without the "medical" mark are not recommended for medical workers and can be used by ordinary people.

The main difference between the two is that the outer surface of medical masks is hydrophobic, that is, blood and sweat cannot be soaked. Without this waterproof layer, frontline health care workers are at risk of getting wet. As the water molecules become liquid, the attraction between the molecules increases, effectively breaking through the mask barrier and allowing viruses to enter. Medical staff are likely to be exposed to patients' blood and body fluids, and the risk will be greater.

How does FFP2 mask protect against the virus?

Viruses usually do not exist alone in the air, but attach themselves to particles such as droplets, dust and dander. The filtering mechanism of N95 masks is precisely to block these fine particles through the high-performance filtering layer in masks to build a protective barrier. Therefore, when wearing a mask, you should pay attention to the face and learn the correct way to wear and remove it.

Is it better to wear more masks?

The key indicator of FFP2 mask protection also depends on air tightness. As long as a qualified product is properly worn, only one mask can achieve the desired protective effect. If you go to crowded places and do not have a medical grade KN95 mask on hand, it is also possible to add a surgical mask outside the anti-haze KN95 mask, and the surgical mask outside can be changed at most several hours.
