Its a very reasonable question, because a virus was originally defined as a 'filtrable agent' Archived Message Posted by Shyaku on May 11, 2020, 5:44 pm, in reply to "Serious question about masks" Its a very reasonable question to ask, one that I wondered about too for exactly the same reason, because the very original definition of a virus, >100 years ago, was as an 'infectious agent that can pass through a filter'. I can find a link or you can. So if you had a suspension of virus in water and forced the liquid through the N95 filter under enough pressure to overcome the surface tension of the water, the virus would likely pass through. However if you had the virus in a scent bottle and spritzed it at the filter, it would not pass through unimpeded, because the droplets (as opposed to the virus) are larger than 0.3 microns, and have enough surface tension that they stay intact as they hit the filter. Any aerosol droplets clinging to the filter will likely dry on the filter, but the resulting desiccated virus will, I think, bind to the fibers of the filter. That's the best I can do without seeing experimental data.
