The KN95 healthcare respirators are designed to help provide respiratory protection for the wearer against certain airborne particles. They meet CDC guidelines for Mycobacterium tuberculosis exposure control. As disposable particulate respirators, they are intended to reduce wearer exposure to certain airborne particles including those generated by electrocautery, laser surgery, and other powered medical instruments.
The KN95 particulate respirators are personal protective equipment (PPE) that are primarily intended to protect the wearer by reducing exposure to harmful airborne particles which are small enough to be inhaled – typically particles less than 100 microns in size. These include airborne particles that may contain biological material e.g. Bacillus anthracis, Mycobacterium tuberculosis, mold and the virus that causes Severe Acute Respiratory Syndrome (SARS), coronaviruses and Influenza.
