For those of us who wear half-face or full-face respirators and
change our filters regularly - great! When you change those filters,
are you cleaning the masks as well? If not, make that part of your
respirator maintenance program, especially during the winter months.
Since most of us will get a cold during this time, those germs will
infiltrate our masks (and filters).
We will continue recirculating our cold if not diligent in our
cleaning regiment. After I dissemble my mask, I use Dr. Bronner's
Peppermint Soap and hot water to remove any nastiness that has
accumulated, plus it smells wonderful.
Something to think about,
