KN95 mask is a mask with a respirator brake. The function of the respirator valve is to work in hot and humid or poorly ventilated or laborious working environment. The respirator with a respirator valve can help you feel more comfortable when you exhale.

"KN95 [1]" is the gb2626-2006 standard of respiratory protective equipment promulgated by the state administration of quality supervision, inspection and quarantine and the standardization administration of China, not a specific product name.

The best feature of it is that it prevents droplets from spreading from the patient's body fluids or blood. The droplets are 1 to 5 microns in diameter. The U.S. occupational safety and health administration (OSHA) requires health workers exposed to TB bacteria to wear N95 or more face masks.

Matters needing attention:

Depending on personal use and environment, it should be replaced immediately if breathing is difficult or uncomfortable, if the mask is contaminated with blood or droplets, if the user feels breathing resistance, if the mask is damaged.

KN95 mask is as long as it meets the standard of KN95 and passes the standard of respiratory products gb2626-2006. It is used for respiratory protection of certain particulate matter, such as dust from polishing, cleaning and processing of mineral, flour and some other materials, etc. It is also suitable for liquid or non-oily particulate matter produced by spraying, which does not produce harmful volatile gas. It can effectively filter and purify the odors inhaled (except poisonous gases). It can help reduce exposure to certain inhalable microbial particles (such as mold, bacillus anthracis, bacillus tuberculosis, etc.), but it does not eliminate the risk of exposure to infection, illness, or death.
