the electro-static properties seem to be about adsorption - so things stick or cling to the mask instead of passing through it.
But the electro-static properties of the mask seem to be about the electro-static forces that were supplied or used in the production of the mask in the first place.
I am not sure that I understand...
What does your mask say about how often you are supposed to change it? Does it say to use a new mask after 4 hours or 6 hours or what?
I have heard something about changing them once they are wet... But the mask I brought from downstairs is wet after around 30 minutes of wear, I would say. Though I suppose the mask I brought is not a cup shaped mask held away from my face. It is a duck-billed one that is not rididly held away from my face and so it tends to suction around my face a bit and get wet from that / get wet in that way.
I do'nt know.
