KN95 Mask


KN95 masks are masks that meet the KN95 standard and comply with the Respiratory Protection GB2626-2006 standard. Where "GB" refers to the national standard, the standard is non-oily particulate filtering efficiency ≥ 95%.


What is KN95?

KN95 as the Chinese standard mask, from the national standard GB2626-2019 "respiratory protective equipment self-absorbing filtered anti-particulate respirator". This standard is a mandatory national standard in China, proposed by the State Administration of Work Safety, and categorized by the National Technical Committee for the Standardization of Personal Protective Equipment (SAC/TC 112). "KN95" is the standard for respiratory protective equipment published by the State Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration, and is not a specific product name. The most important feature of these masks is that they can prevent droplet transmission caused by splashes of bodily fluids or blood from patients.


Medical VS fee medical KN95

As we know, there are also medical and non-medical KN95 masks. The difference between them is that medical masks have a hydrophobic treatment of lotus leaves that repel water. This will be the medical personnel often contact with alcohol, blood, etc. blocked. We, ordinary people, are not likely to come into contact with alcohol or blood, so we just need to change the mask regularly.


KN95 can do

The KN95 protective mask is used for respiratory protection against certain particles such as dust from grinding, sweeping and handling minerals, flour and certain other materials. It is also suitable for liquid or non-oily particulate matter that does not produce harmful volatile gases due to spraying. Can effectively filter and purify the inhaled abnormal odor (except toxic gases).


KN95 can not do

◆ Respiratory infections are not only transmitted through the respiratory tract;

◆ Fit - A mask that is not designed to fit the user's face will cause leakage;

◆ The mask's tight-fitting construction and efficient filtration can increase breathing resistance and reduce comfort;

◆ Protective masks can reduce the concentration of harmful substances by up to 90% when fit and proper use requirements are met.

◆ The government has not established safe exposure limits for pathogenic microorganisms, and respiratory protection only reduces the risk of illness but does not eliminate the risk.

◆ May help reduce exposure levels to certain respirable microbial particulate matter (e.g., mycobacteria, Bacillus anthracis, Mycobacterium tuberculosis, etc.). However, it does not eliminate the risk of exposure to infection, illness, or death.


Note on use

The function of the breathing valve is to help you feel more comfortable when exhaling in hot and humid or poorly ventilated work environments or workloads with a breathing valve.

Use time: Depends on the individual use and environment, but when you find breathing difficulty or discomfort, the mask is contaminated with foreign objects such as blood stains or droplets, the user feels a greater breathing resistance, and the mask is damaged, etc., you should replace it immediately.
