How much do you know about the KN95 masks?

According to professionals, KN95 masks are masks with filtration efficiency (greater than or equal to 95%) for particulate matter in China, and N95 masks are tested (standard) in the United States, but the code names are different. Also, from a particulate filtration perspective, the effect is practically the same.

When do I need to replace the KN95 mask?

When the following situations occur, the KN95 mask should be replaced in time:

1. When the respiratory impedance increases significantly;

2. When the KN95 mask is damaged or damaged;

3. When the KN95 mask cannot fit closely with the face;

4. The KN95 mask is contaminated (such as when it is stained with foreign objects such as blood stains or droplets);

5. This KN95 mask has been used in individual wards or patient contact (because the mask has been contaminated).

What are the functions and uses of KN95 masks?

The filtration efficiency of KN95 masks for particles with an aerodynamic diameter of 0.3µm reaches more than 95%. The aerodynamic diameter of air bacteria and fungal spores mainly varies between 0.7-10µm, which is also within the protection range of KN95 masks. Therefore, KN95 masks can be used for respiratory protection of certain particles, such as dust generated during grinding, cleaning and processing of minerals, flour and certain other materials, and also suitable for liquid or non-oily products generated by spraying that do not produce harmful Particulate matter of volatile gases. Can effectively filter and purify inhaled abnormal odors (except toxic gases), help reduce exposure to certain inhalable microbial particles (such as mold, anthrax, tuberculosis, etc.), but does not eliminate contact infection, illness or death risks of.

What should we pay attention to before using KN95 masks?

1. Wash your hands before wearing a KN95 mask, or avoid touching the inner side of the mask with your hands during the process of wearing the mask to reduce the possibility of the mask being contaminated.

2. Distinguish the inside and outside, top and bottom of the mask.

3. Do not squeeze the mask with your hands. KN95 masks can only isolate the virus on the surface of the mask. If you squeeze the mask with your hands, the virus will soak through the mask with droplets, which may easily cause virus infection.

4. Try to keep the KN95 mask in good contact with the face. The simple test method is: after wearing the mask, exhale forcefully, and the air cannot leak from the edge of the mask.

5. The KN95 mask must be in close contact with the user's face, and the user must shave the beard to ensure that the mask can fit tightly to the face. The beard and anything between the mask seal and the face will cause the mask to leak.

6. After adjusting the position of the KN95 mask according to your face shape, use the index fingers of both hands to press the nose clip along the upper edge of the mask to make it close to the face.

Xiamen PinzTec Co., Ltd has various KN95 masks that can provide the increasing of products, and make them more effective, reliable, and consistent.
