How can we test the quality of a mask when we buy it? There are the following methods:

 

1.Paper will burn when it encounters fire, and melt-blown cloth will melt when it is involved, and will not burn directly;

2.Masks with melt-blown cloth can have an electrostatic adsorption effect, and qualified masks can absorb a large amount of paper dust; (shred the paper a little before testing);

3. Pour water into the mask, the qualified mask will not leak.
