no but there are patents for the n95 and similar masks that describe what makes it all work. US20100313890A1 - Protective mask with breathable filtering face seal - Google Patents
Stop spreading misinformation. Cotton masks do work. They stop droplets and cut down aerosol intake by 50%. Are they as effective as n95? No. Are they ineffective? Are they no different than being in public without one? No.

i understand the aerosol/bigger particle stoppage, and it being better than nothing.
