KN95 mask refers to a mask that meets the KN95 standard and complies with the GB2626-2006 standard for respiratory protective equipment.
"KN95" is a respiratory protection product standard published by the National Quality Supervision, Inspection and Quarantine Bureau and the National Standardization Administration, not a specific product name. The biggest feature of this type of mask is that it can prevent droplet infection caused by the patient's body fluid or blood splash.
"KN95" is the GB2626-2006 standard for respiratory protection products published by the National Quality Supervision, Inspection and Quarantine Bureau and the National Standardization Administration, and is not a specific product name. As long as it meets the KN95 standard and passes the GB2626-2006 standard for respiratory protective equipment, it can be called a "KN95 mask".
In the GB2626-2006 standard, KN95 is the standard for dust protection, which is cheap and easy to adopt by related dust industries. N95 masks are used for occupational respiratory protection, including certain dust particles (such as dust, smoke and other non-oily particles protection).
The biggest feature of the KN95 mask is that it can prevent droplet infection caused by the patient's body fluid or blood splash. The size of the droplets is 1 to 5 microns in diameter. The U.S. Occupational Safety and Health Administration (OSHA) stipulates that medical personnel exposed to tuberculosis bacteria must wear masks above the N95 standard for medical institutions.
KN95 respirator is a respirator with a breathing lock. The function of the breathing valve is to work in hot and humid or poorly ventilated or labor-intensive working environments. Using a respirator with a breathing valve can help you feel more comfortable when you exhale.
Use time: It depends on the personal use situation and environment, but when breathing is difficult or uncomfortable, the mask is contaminated such as blood stains or droplets and other foreign objects, the user feels that the breathing resistance is increased, the mask is damaged, etc., it should be replaced immediately.
Respiratory infections are not only spread through the respiratory tract;
Preventive measures should precede exposure;
The tight structure and high-efficiency filtration of the mask will increase breathing resistance and reduce comfort;
Suitability-If the mask design does not fit the user's face shape, it will cause leakage;
Under the requirements of suitability and correct use, protective masks can reduce the concentration of harmful substances by 90%.
The government has not established a safe exposure limit for pathogenic microorganisms, and respiratory protection only reduces the risk of illness, but does not eliminate the risk.
