This is a quick, easy way to make a box that can hold a temperature (between 70C/158F and 85C/185F) to disinfect an N95 mask of Coronavirus without damaging the masks filtration, fit, or elastic. Please see the Sources page for where this number came from.

This is intended for people and groups who need to re-wear a used - but otherwise unsoiled - N95 mask on back-to-back shifts (first responders, nursing home workers, essential retail employees). If you can let the mask sit for 72+ hours before rewearing, this is not necessary!

This can be built for around $40, with no specialized tools. It requires one run to a local big-box hardware store, and one hour to assemble.

Designs are included for boxes that use - with low waste - a half, third, and quarter of a sheet of a 4' x 8' piece of rigid foam insulation.
