Material: non-woven, KN95 solvent spray, insulation cotton
Purpose: Anti-virus protection, prevent dust particles, smoke, pollen, dust, bacteria, etc.
In N95 masks:
The N95 mask can isolate smaller particles and fit the face more closely, it is not easy to leak air from the outer periphery, and the filtering efficiency of the particles can reach 95% under standard conditions.
The mask n95 is not a disposable mask. In this special case (resource shortage), it can be reused. But there are conditions:
1. When n95 is contaminated by saliva, blood, tears and other body fluids, it should be replaced.
2. The user obviously feels that the breathing resistance is greater than before and must be replaced
3. The mask is damaged and must be replaced 4. It is recommended to replace it after 4 times of use.
However, if people go to the hospital, come into contact with an infected person or suspect that they are infected, the mask cannot be reused.
Five-layer filtering function:
1. The first layer: spunbonded fabric, filter micron dust
2. The second layer: filter industrial pollutants, automobile exhaust, allergies to second-hand fireworks powder
3. The third layer: activated carbon fabric, benzene and smaller micron filter function
4. The fourth layer: the density of the filter, the smaller material
5. The fifth layer: spunbonded fabric, filtering all kinds of harmful substances
