The Conventional Face Masks testing methods

If it is a 3-ply mask, logically, it would need to have 3 layers. Cut open the mask and you should see a very obvious 3-layers, as shown below. The 3 layers would typically consist of a Translucent piece (top), White piece (middle), and the coloured piece (Green, Blue, or even White).

 

2、Water Test

Surgical masks, not only protect others from your cough and sneeze, they also provide protection against others’. Therefore, the outer layer is designed to be waterproof!

Fold your mask such that the outer side forms a funnel and pour some water into it. You should be able to see that the mask is holding up the water properly. Apart from that, touch the bottom of the funnel, make sure it is not wet or damp. The following video illustrates this test.

 

3、Fire Test

The middle layer is a filter, not a piece of paper. Therefore, if you were to light it with a flame, it WILL NOT catch fire! The following video illustrate the outcome of burning the middle layer, compared with burning a piece of tissue.
