[1/2]Reusable mask test done. Note filtration data is my test aerosol, my face. Data also are all using the Fix The Mask to avoid issues with face seal variation between tests. My pressure drop measurement is not great so take that with a grain of salt(±0.05 typ).

[2/2] Note that most KF94's are all 95+% in this test, and after 40hrs of use are all still 95%. Highlights to me KF94/KN95/N95 provide better protection, even with re-wear and total cost is still less.
