Following these guidelines concerning using and disposing of KN95 protective respiratory face masks is important in maintaining your health and that of your community.
If your KN95 respirator is damaged or soiled, or if breathing becomes difficult, you should remove the respirator, discard it properly, and replace it with a new one. To safely discard your KN95 respirator, place it in a plastic bag and put it in the trash. Wash your hands after handling the used respirator.
KN95 respirators are not designed for children or people with facial hair. Because a proper fit cannot be achieved on children and people with facial hair, the KN95 respirator may not provide full protection.
Ideally should be discarded after each patient encounter and after aerosol-generating procedures. It should also be discarded when it becomes damaged or deformed; no longer forms an effective seal to the face; becomes wet or visibly dirty; breathing becomes difficult; or if it becomes contaminated with blood, respiratory or nasal secretions, or other bodily fluids from patients.
Please note: KN95 masks are NOT NIOSH approved N95 masks. The CDC has recently stated that KN95 masks may be a suitable alternative when Niosh N95 masks are not available.
Filtering facepiece respirators (FFR) are subject to various regulatory standards around the world (see examples below) and provide a much higher level of protection with face form fitting and greater pressure drop. To claim compliance with the particular standard as listed below, these respirators must meet or exceed required physical properties and performance characteristics, which can vary according to the regulatory bodies of different countries.
N95 (United States NIOSH-42CFR84)
KN95 (China GB2626-2006)
FFP2 (Europe EN 149-2001)
