With the shortage of mask materials, many people order masks from abroad, such as the kf94 face mask in South Korea, do you know the difference between it and kn95 face mask?

KN95 face mask
In fact, there is no difference between these two types of protective face masks. The KN series is a Chinese standard, and the KF series is a Korean standard. Their filtering effect is similar, that is, KN95 = KF94.

"KN95" is the GB2626-2006 standard for respiratory protective equipment promulgated by the National Quality Supervision, Inspection and Quarantine Bureau and the National Standardization Management Committee, and is not a specific product name. As long as it meets the KN95 standard, and can pass the respiratory protective equipment GB2626-2006 standard, it can be called "KN95 mask".

KN95 or KF94, these two masks have one thing in common-KN masks and KP masks have no anti-permeation requirements. Both masks are not aimed at medical standards and cannot be used for medical institution protection. However, these two masks are enough for our ordinary people's daily protection, you can choose with confidence.

Regarding whether the face mask can be reused, both of them can be reused, but there is no official number for the specific number of times. According to personal use and environment, the mask must be replaced in time when the following situations occur:
