NIOSH disposable particulate filter face mask Anti-Pollution N95 dust face mask respirator

Product Description

NIOSH N95 STANDARD INTRODUCTION:

N95 mask can block 95% of the last micron (less than 0.3 μ m) particles. The effect of N95 mask on blocking fine particles is quite certain. It is one of the best masks to choose in haze days. However, it has great resistance when breathing, so it is not suitable for the general public to wear for a long time, and it should be avoided to use it repeatedly.​

Performance limitations:

• Infectious diseases of the respiratory tract are not only transmitted through the respiratory tract;

• Preventive measures should precede exposure;

• The tight structure of the mask and high-efficiency filtration will increase breathing resistance and reduce comfort;

• If the mask design is not suitable for the user's face shape, it will affect the suitability and will cause leakage;

• Under the requirements of suitability and correct use, protective masks can effectively reduce the concentration of harmful substances by 90%;

• The government has not established safe exposure limits for pathogenic microorganisms. Respiratory protection can only reduce the risk of illness, but it cannot eliminate the risk.
