Simple Trick To Check If A Mask Is Doing Its Job Or Not

This video that surfaced on Facebook, shows how a lady is testing masks she got from China. In this video, she demonstrates how a lighter on fire, cannot be put out with a good mask on, no matter how forcefully you blow through the mask. She then picks up a mask that she got from China, and displays how effortlessly the fire on the lighter gets put out, despite the mask being on. She says that if you can put out the fire while having the mask on, the mask is not doing its job, and this will not serve its purpose while being used outdoors.
