No, washing KN95 masks in the washing machine is not recommended.

In the face of the ongoing global pandemic, wearing masks has become a crucial part of our daily routine to protect ourselves and others from the spread of COVID-19. KN95 masks, with their high filtration efficiency, have gained popularity as a reliable choice for safeguarding against airborne particles. However, as the need for masks persists, questions arise about their maintenance and reusability. One common question that arises is whether you can wash a KN95 mask in the washing machine.

In this article, we will explore the dos and don’ts of KN95 mask care, provide alternative cleaning methods, answer frequently asked questions, and offer some final words of guidance.

Dos and Don’ts of Wash A Kn95 Mask In The Washing Machine


  • Proper Storage: Store your KN95 masks in a clean, dry place. A paper bag or a breathable container is ideal for preventing contamination.
  • Hand Hygiene: Always wash your hands thoroughly with soap and water or use hand sanitizer before handling your mask.
  • Secure Fit: Ensure the mask fits snugly on your face, covering both your nose and mouth. Adjust the nose clip if necessary to minimize gaps.
  • Limited Touching: Avoid touching the front of the mask while wearing it, as this could transfer contaminants to the surface.
  • Regular Inspection: Periodically inspect your KN95 mask for any signs of damage or dirt. If it’s soiled or torn, it’s time to replace it.


  • Washing Machine: Do not wash KN95 masks in the washing machine. This can compromise their effectiveness.
  • Submerging in Water: Avoid immersing KN95 masks in water or using soap, as it can interfere with the mask’s filtration capabilities.
  • Excessive Handling: Refrain from frequent adjustments or touching the mask while wearing it, as this can increase the risk of contamination.
  • Sharing Masks: Sharing masks with others is discouraged, as it can lead to cross-contamination.
  • Reusing Excessively: While KN95 masks are designed for limited reuse, using the same mask for an extended period may reduce its efficacy. Replace it when it becomes damaged or difficult to breathe through.

Steps To Avoid Washing KN95 Masks in the Washing Machine:

Step 1

Remove Carefully: When you’re done using the mask, take it off by grasping the ear loops or ties without touching the front of the mask.

Step 2

Store Safely: Place the used KN95 mask in a clean, breathable bag or container until you can properly dispose of it.

Step 3

Wash Hands: After removing the mask, wash your hands thoroughly with soap and water or use hand sanitizer.

Step 4

Dispose Properly: KN95 masks are typically not meant for long-term reuse. Discard them in a lined trash can.

Alternative Washing Methods For KN95 Masks:

While washing KN95 masks in a washing machine is not recommended, there are alternative methods to ensure your masks stay clean:

  • UV-C Light: Some devices on the market use UV-C light to disinfect masks. Follow the manufacturer’s instructions for proper usage.
  • Steam Treatment: You can use a garment steamer or steam from boiling water to disinfect your mask. Hold the mask at a distance to prevent damage and ensure all parts receive steam.
  • Hydrogen Peroxide Vapor: Some healthcare facilities use hydrogen peroxide vapor to disinfect masks. This method is more advanced and typically not suitable for home use.
  • Alcohol Wipes: Gently wipe the surface of the mask with a disinfectant alcohol wipe. Make sure the mask is completely dry before wearing it again.
  • Rotation: If you have multiple KN95 masks, rotate them to allow each one to rest for at least 72 hours between uses. This helps any contaminants on the mask’s surface to naturally degrade.


Can I use a KN95 mask if it gets wet from rain or sweat?

Answer:  If your KN95 mask gets wet, it’s recommended to replace it with a dry one. Moisture can compromise the mask’s filtration effectiveness.

Can I reuse a KN95 mask after decontaminating it with alcohol or other disinfectants?

Answer:  While disinfecting with alcohol wipes is an option, the effectiveness of the mask may diminish with repeated use. If the mask becomes damaged or difficult to breathe through, replace it.

How should I store KN95 masks when not in use?

Answer:  Store KN95 masks in a clean, dry place, preferably in a breathable container or a paper bag. Avoid placing them in pockets or bags where they can be exposed to contaminants.

Is it safe to use KN95 masks that have an exhalation valve?

Answer:  KN95 masks with exhalation valves may not provide adequate protection to others, as they allow unfiltered air to be exhaled. Consider using masks without exhalation valves in situations where the protection of others is important.

How can I tell if my KN95 mask is genuine and of good quality?

Answer:  To ensure your KN95 mask is genuine and of high quality, purchase from reputable suppliers and manufacturers. Look for certification marks, such as NIOSH or FDA, and check for proper labeling and packaging.

Final Words:

In the battle against COVID-19, using personal protective equipment like KN95 masks is essential. While washing KN95 masks in a washing machine may seem like a convenient solution, it’s important to heed the advice against it. KN95 masks are designed with a special static charge that traps viruses, and washing them with water or soap can significantly reduce their effectiveness.

Instead, focus on proper storage, limited handling, and regular inspection of your masks. If your KN95 mask becomes dirty, damaged, or difficult to breathe through, it’s time to dispose of it and replace it with a new one. By following these guidelines, you can maximize the effectiveness of your KN95 masks and continue to protect yourself and those around you from the spread of COVID-19. Stay safe and stay vigilant.
