The Centers for Disease Control and Prevention listed KN95 masks (the Chinese version of the N95) as suitable alternatives to N95s when N95s are not available.
Figure 1 indicates that a KN95 mask has similar filtration efficiency as a N95 when new. However, it acts differently (larger variation) after H2O2 sterilization and becomes very inefficient after ClO2 sterilization.
So N95 isn’t as negatively effected after these types of sterilizations? Any comments on whether N95 is more practical/​appropriate for everyday people?
