KF94 is a South Korean general-public mask standard. Most KF94 masks feature a boat-style design and attach to the face using ear loops. The "KF" stands for "Korea Filter."
KF94 masks are certified by the South Korean Ministry of Food and Drug Safety in a manner similar to how the US-based NIOSH certifies N95 respirators. KF94 are not considered equivalent to US N95; a different Korean standard, "1st class" (KMOEL-2017-64) is more like the NIOSH N95 standard. K94 is a general-public mask standard, not designed for industrial or occupational use like NIOSH N95.
In addition to KF94, in Korea there are also "KF80" masks, which meet a less rigorous filtration standard.
The 3M Aura is a N95 respirator with a boat-style design akin to the popular boat-style KF94.
