Our KN95 face masks are built to spec to feature variation in the maximum pressure to ensure they are able to withstand pressure during inhalation and exhalation.
To understand the efficacy of our bacteria masks, here are some definitions for the more technical terms:-
Filter Performance
This is the metric used to analyze what amount of concentration of specific aerosols (in this case NaCl) that pass through the KN95 face masks. Our face masks have a filter performance = 95%.
Total Inward Leakage
Refers to the amount of NaCl that entered the KN95 face mask through the faceseal leakage as well as filter penetration while the wearer performed a number of exercises in the test chamber.
Inward Leakage
Refers to the amount of NaCl that entered the KN95 Corona Virus face mask while the wearer inhaled and exhaled for about 3 minutes in a designated test chamber.
Pressure Drop
Refers to the air resistance as the wearer breathes through a medium such as our KN95 face masks.
