Is there no other option for you rather than reusing your Kn95 mask? Then, the thing that you must make sure is – a good sanitizing of every inch of the mask. How can you do it perfectly? Keep following to learn in detail.

How to Sanitize Kn95 Mask  

To kill the germs of Covid-19 of your Kn95 mask only shortlisted methods are recommended:

Heat

Another group of researchers at the University of Tennessee have made an experiment with heat. The researchers took a used Kn95 mask and heated it up at 70C for 30 minutes at a stretch. To their utter surprise, they found that the germs of Covid-19 are no more and the filter is all okay.

Ethanol spray

Just like the previous three, ethanol spray is also a tested way to sanitize Kn95 mask. For this, your ethanol solution must be pure and the solution must be everywhere of the mask.

The last note for you is that not any of the methods is approved by the manufacturers but amid such a crisis, you are left with no other option rather than adopting any of our recommended procedures. 

UV radiation

Using UV radiation to sanitize your Kn95 mask is another promising method, already being adopted by some hospitals. While performing this method, you must make sure that radiation falls all over the mask properly with 260/285 nm. Otherwise, all your attempts will go in vain.

VHP

VHP, the acronym of Vaporized Hydrogen Peroxide has been a popular means of mask sanitization since the outbreak of Covid-19.The researchers of Duke Health have already granted this method - sound. They have found that vaporized Hydrogen Peroxide is immensely successful in permeating the layers of the mask and killing the Covid-19 germs. They have also stated that using vaporized Hydrogen Peroxide doesn’t cause any type of deterioration to the mask. 

So, you can adopt the method with the utmost reliance although amid the lockdown getting vaporized Hydrogen Peroxide mightn’t be easy. 

Warning

Don’t do the following two things with your Kn95 mask:

  • Saturating the mask with liquid alcohol or aerosol 
  • Washing using soap solution

You may perform any of the procedures with your mask but that will leave you with unseen danger.Because, sanitization with any of these destroys filter medium material of the mask. Eventually, your mask will lose its effectiveness. 

Again, using ethanol spray often reduces the effectiveness of a Kn95 mask. So, you better try to avoid this method as much as possible.

Final words

To sum up, the best thing for you is - discarding the Kn95 mask as long as possible. But, when reusing becomes the only solution, sanitizethe current one with utter care following any of our recommended methods. And, as soon as you get a new mask, throw away the used one to ensure the ultimate safety.
