The Physics of the N95 Face Mask
IT'S 2022, AND by now we've all been wearing masks for nearly two years. AND unless you are a surgeon or a construction worker who Was already wearing them daily, in those two years you've probably learned a lot about them -- which ones you like best, where to get them, and whether you have any extras stashed in a coat pocket or somewhere in your car. But do you know what makes the prized N95 maskso special? Let's find out. Electric Charges & health food Finally, The masks in regular Cloth or paper face filter out Particles by affix blocking them -- but The fibers in an NIOSH N95 mask also use a great physics trick. These fibers are electrically charged. Electric charge is one of the fundamental properties of all particles. Just about everything around you is made of three particles: the proton, the electron and the neutron. (For now, Let's ignore muons and neutrinos -- Both Fundamental Particles that Actually Exist -- As well as other Particles that are theore...
