The N95 mask is one of nine NIOSH certified particle respirators. “N” stands for not resistant to oil. “95” means the concentration of particles in the mask is more than 95% lower than that outside the mask when exposed to a specified number of specialized test particles. 95% of these values are not averages, but minimums.

N95 is not a specific product name, as long as it meets the N95 standard and is approved by NIOSH. The protection level of N95 means that the filtration efficiency of mask filter material for non-oily particulate matter (such as dust, acid mist, paint mist, microorganism, etc.) can reach 95% under the testing conditions stipulated by NIOSH standard.

The KN95 Face Mask Filtering

Below is some of the particulates that the KN95 face mask can filter.

Air pollutants (including PM10, PM2.5)

KN95 is the industry standard, which means the mask provides the desired efficiency of filtering 95% of particles with a median mass of 0.3 microns in diameter. Therefore, our masks can protect you from PM10, PM2.5, and even smaller particles.

 KN95 Face Mask Filter


KN95 mask can protect you from pollen. The filtering efficiency is more than 95% under the particle size of 0.3 livability m, while the particle size of ordinary pollen is around 10-1000 livability m.

Bacteria and bacteria

KN95 mask can help reduce exposure to biological substances such as bacteria and bacteria. However, please note that wearing a mask does not eliminate the risk of infection, as it depends on the correct size of the wearer. KN95 masks are not intended for use in clinical settings such as hospitals or dental clinics.

 KN95 Face Mask Filtering

Automobile exhaust and smoke

The activated carbon layer in our filter deodorizes the air and helps reduce vehicle exhaust in the surrounding air.

Animal allergen

Our KN95 face mask protects you from animal allergens. The efficiency of our filter is more than 95% when it is 0.3m in size, while the particle size of normal animal allergen particles is about 5-10 in size.
