Washing KN95 masks with soap and water is not recommended. The masks have a special static charge that traps viruses, and washing them can damage the material and reduce their filtration efficiency. Instead, there are several methods recommended for cleaning and disinfecting KN95 masks, including steaming in a microwave, using UV light, or leaving the mask in a paper bag for several days.

Dos and Don’ts of Wash A Kn95 Mask


  • Wear the Mask Properly: Always ensure that you wear the KN95 mask correctly, covering both your nose and mouth. A snug fit is essential for optimal protection.
  • Replace When Damaged: If your KN95 mask becomes damaged, soiled, or difficult to breathe through, replace it with a new one. Damaged masks may not provide the necessary filtration.
  • Perform Hand Hygiene: Before putting on and after removing the mask, practice proper hand hygiene. Wash your hands thoroughly with soap and water for at least 20 seconds or use hand sanitizer with at least 60% alcohol.
  • Dispose of Used Masks Properly: After each use, place the used KN95 mask in a sealed plastic bag and dispose of it in a trash bin with a lid. Avoid touching the front of the mask when removing it.


  • Do Not Wash: It’s crucial to understand that washing KN95 masks with soap and water is not advisable. These masks are designed for single-use, and attempting to wash them can damage the mask and reduce its effectiveness.
  • Do Not Reuse: KN95 masks are intended for single-use only. Reusing them can compromise their ability to filter particles effectively and may not provide the protection you need.
  • Avoid Touching the Front: Avoid touching the front of the mask while wearing or removing it, as this can transfer contaminants to your hands and potentially lead to infection.
  • Do Not Share Masks: KN95 masks are personal protective items and should not be shared with others. Sharing masks can increase the risk of disease transmission.
  • Don’t Ignore Proper Fit: Always ensure that the mask fits snugly on your face. Leaving gaps or wearing it loosely can reduce its effectiveness in protecting you from airborne particles.

Now, let’s explore effective methods for cleaning and disinfecting your KN95 mask.

How To Wash KN95 Mask:

Washing a KN95 mask with soap and water is not recommended, as mentioned earlier. However, there are alternative methods you can use to clean and disinfect your mask without compromising its effectiveness:

  1. Steaming in a Microwave:
    • Place a small bowl of water in the microwave along with the KN95 mask.
    • Heat the mask and water in the microwave for about 2-3 minutes until the water boils, creating steam.
    • Let the mask cool before using it again. The steam can help disinfect the mask without damaging it.
  2. Using UV Light:
    • Some UV sanitizing devices are designed specifically for disinfecting masks. Follow the manufacturer’s instructions for safe and effective disinfection.
  3. Leaving the Mask in a Paper Bag:
    • After each use, place the KN95 mask in a clean paper bag, ensuring it remains dry.
    • Leave the mask in the paper bag for at least 72 hours. This allows any potential viruses to become inactive on the mask’s surface.

These alternative methods can help maintain the cleanliness and effectiveness of your KN95 mask without resorting to washing, which can damage the mask’s filtering properties.
