KN95 face masks are comfortable and well-fitting. They have a Bacterial Filtration Efficiency* (BFE) value of ≥95%. 95% filter efficiency level provides better breathability and protection
*Bacterial Filtration Efficiency (BFE) means that the filtering capacity is measure in both directions. The fewer bacteria penetrate the material, the better the efficiency. It is comparable to N95 face masks and complies with the BFE ≥95%.
