Introduction: Easy Virus Deactivation Kit for Reusing Mask

First the disclaimer: Do not reuse soiled and wetted masks! Do not share masks! THIS IS NOT A PROPER METHOD FOR MEDICAL STERILIZATION. This should only be used to reduce waste and extend mask usage when no other methods are viable.

The principle of virus deactivation by temperature method is based on the paper

Human Coronaviruses: Insights into Environmental Resistance and Its Influence on the Development of New Antiseptic Strategies

"Sensitivity of SARS-CoV to temperature has also been assayed. The exposure of the virus to a temperature of 56 °C over 30 min reduced virus titer under an undetectable level."
