What do you know about what makes the prized N95 mask so special?
You might think that an electrically-charged N95 face mask would only be good for stopping electrically charged objects, but youLet's start with a simple demonstration you can do at home. Start with a plastic pen and one of those plastic grocery bags. Now rub the pen with the bag. It should become electrically charged. If you can’t get it to work, you might need to change up materials—you could try rubbing the plastic pen against some wool or your hair.
Did you notice in my demo that some of the paper is attracted and then repelled by the plastic pipe? That can happen. When the paper hits the positive pipe, some of the negative electrons transfer from the paper to the pen. Now the paper is also positive and the pen repels it to make it fly away. With an N95 fiber, you don't have to rub it with some other material to get it charged. The fibers in the mask are created from an “electret” material; this word comes from combining electric and magnet. No, it's not an—it is a permanently electrically charged object, just in the way that a bar magnet on your fridge is.
