This woman is awesome. This is Christa Meagan. She is a Senior Industrial Hygienists. She explains from an expert point of view something that should be obvious to anyone with a few operating synapses. Masks do not work. They leak around the sides..period. The weave is not fine enough to stop a virus. That is with the best N95 masks. Think about all the idiots that run around with piece of terry cloth over their face thinking they are protected.
