What's the difference between KN95 and N95?

N95 mask actually is a kind of respirator, a kind of respiratory protection equipment, which is designed to fit the face more tightly than the ordinary mask, and can filter the particles in the air very effectively. The character "N" indicates that it can be used to protect 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 very small (0.3 micron level) test particles.

By design, if ranked according to the priority of the wearer`s own protective ability (from high to low): N95 masks > surgical masks > ordinary medical masks, ordinary cotton masks.

KN95 is an industry-standard and means that the mask provides the intended effectiveness of filtering 95 percent of particles with a mass median diameter of 0.3 micrometers. Therefore, our mask can protect you well from PM10, PM2. 5, and even smaller particles. The Airinum Urban Air Mask can protect you from pollen.

If worn correctly, the N95`s filtering ability is better than the ordinary mask and medical mask. However, even if worn in full compliance ,100 per cent of the risk of infection or death can not be eliminated.

KN95 is one of the levels specified in the Chinese Standard GB2626-2006.

N95 is one of the grades specified in 42 CFR 84.

The technical requirements and test methods of these two levels are basically the same.

are the filtration efficiency reached 95% under the corresponding standard.

How long can a KN95 mask be used?

Nowadays, there is no clear conclusion about the best wearing time of N95 masks abroad, including WHO, and there is no relevant regulation on the use time of masks in China.

Some researchers have studied the protective efficiency and wearing time of N95 medical masks. The results show that the filtration efficiency remains above 95% N95 wearing the masks for 2 days, and the respiratory resistance changes little, and the filtration efficiency decreases to 94.7% for 3 days.
