Face mask, as the most important protective articles at present, have different classifications.
According to the filtering level, the integrated filter can confirm the performance level of the filter dust:
P1: General capacity filtration efficiency: ≥95.0%;
P2: Medium capacity filtration efficiency: ≥99.0%;
P3: Higher filtration efficiency: ≥99.99%.
The higher the dustproof level of the filter element, the smaller the diameter of the dust particles, and the higher the performance of the dust filter.
In short, the way to choose a mask is to check the type of protection and the level of protection.
