Moist heat decontamination is
achieved by treating masks with
149°F steam for 30 minutes.
Key steps include 1. placing the
mask(s) in a paper bag, 2. filling
the multi-cooker with a half inch
of water and 3. setting the bag on
a rack inside of the multi-cooker.
S&T verified these conditions inactivate
the virus below detectable
limits in culture media and
simulated saliva, while the masks
still meet performance specifications
after five treatments.
Further research will determine if
the virus is also inactivated in
lung fluid, and whether this process
is effective for additional

(Vital PPE such as filtering facepiece respirators (FFRs) is in limited supply due to high
demand. The S&T has identified programmable multi-cookers with a sous vide or equivalent
setting, as a suitable means to treat FFRs using moist heat at home. Courtesy of Department
