Made in Korea DOBU N95 USA certification Mask(30P)

A company that's been making masks for 50 years.
It is a mask that is certified as NIOSH in the U.S.
KF94 mask is also very good, but it is made with more adherence than KF94.
Masks certified as NIOSH in the U.S. are also supplied as actual medical masks.
I trust DOBU mask more because it is a supplier of the Korea Centers for Disease Control and Prevention.
