How is the classification of protective masks?

If there are only harmful gases, the general tank selection can meet the requirements; if it contains dust, then the tank should be integrated. According to the filtering level(3 Ply Face Mask Wholesale), 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(Nonwoven Face Mask On Sales) of the filter tank, the smaller the diameter of the dust filter particles, and the higher the performance of the dust filter.

All in all, the way to choose a tank is to check the type of protection(Dustproof Face Mask Supplier), check the protection level, and see if there is dust.
