Lets list details and differences between them according to 3m standards.  Total inward leakage (TIL) -  N95 = nil ,  KN95 = ≤ 8% leakage . Inhalation resistance -   N95  = ≤ 343 Pa , KN95 = ≤ 350 Pa. Exhalation resistance -  N95   = ≤ 245 Pa , KN95 = ≤ 250 Pa . Exhalation valve leakage -    N95  =  ≤ 30 mL/min , KN95 =  0 Pa ≥ 20 sec . Force applied -  N95  = -245 Pa , KN95 =  -1180 Pa . *N95 masks,
