Is there a difference between KN95 and N95?
The n95 mask is actually a respirator, a respirator that is designed to be more tightly attached to the face than a common mask and can filter particles in the air very effectively. where n denotes notresistanttooil, which can be used to protect against non-oil suspended particles;95 means that the filtration efficiency is greater than or equal to 95%, indicating that after careful testing, this respirator can block at least 95% of the very small (0.3-micron grade) test particles.
From the design, if ranked according to the priority of the wearer`s own protective ability (from high to low): N95 mask > surgical mask > general medical mask > ordinary cotton mask.
If worn correctly, the N95 filters better than the normal and medical masks. However, even if worn in full compliance, the risk of infection or death cannot be eliminated 100%.
KN95 is one of the levels specified in the Chinese Standard GB2626-2006.
N95 is one of the levels specified in the US Standard 42 CFR 84.
These two levels of technical requirements, testing methods and so on are basically the same,
The filtration efficiency is 95% under the corresponding standard.
