KF' stands for 'Korean Filter'. Korean masks must be certified by the Korea Food & Drug Administration (KFDA) and will be rated KF80/94/99 depending on their performance. Korean masks are required to test for CO2 clearance, which prevents CO2 from building up inside the mask. Masks are equivalent to P2 filtration and filter out 94% of particulate matter.
