KN95 Masking Instructions

protect the cave KN95 mask instructions banner


  • If possible, wash or sanitize your hands immediately before and after putting your KN95 on and immediately before and after taking it off when planning to reuse it.
  • New KN95 masks are folded. Unfold the mask and carefully flatten the metal nose clip. This step is not necessary when reusing your mask.
  • Cradle the mask in your hand with the interior side up and the nose clip toward your fingertips.
  • Place your chin into the lower part of the mask and the nose piece onto the upper part (bridge) of your nose.
  • Place the straps of the mask over each of your ears while supporting the mask.
  • Adjust the metal nose clip using fingers from both hands to mold the clip to the shape of your nose.
  • Adjust fit as necessary to create a seal against your face.
  • Exhale rapidly to check for air flow in the area around the nose clip and your chin area. Adjust again to remedy the air flow issue.
  • If you still feel significant air flow, you may be able to tie a small knot in the ear loops to shorten them or use an ear relief device to improve tightness of fit.
  • Significant facial hair (more than 3 days growth) adversely affects the ability of the KN95 to form a tight seal around your face and thus reduces the KN95’s effectiveness at protecting you from COVID-19. Therefore, parts of your face that come in contact with the KN95 should be free of significant facial hair.
  • If you wear glasses and find fogging to be a nuisance, wash the lenses with soapy water and shake off the excess before putting on your mask (wipe off nose piece to minimize skin irritation).


  • DO NOT attempt to wash or sanitize your KN95 with any type of chemicals. With proper care, your KN95 should be reusable for an extended period of time.
  • To keep your KN95 clean between uses, store your mask in a safe location that other people cannot access and where it will not get wet or be subjected to excessive heat. A dry paper bag works well for storing your KN95.


  • You should replace your KN95 when it:
    • Becomes soiled
    • No longer covers the nose and mouth
    • Has stretched out or damaged ties or straps
    • Cannot stay on the face
    • Has holes or tears in the fabric
  • A KN95 may be disposed of in the normal trash.
