Soap and water and a shop vac.
At lunch and at 4P.
Air dry.
Change cans and filters as necessary.
And good ventilation otherwise, anyway.
Happy lungs.
Happy me. :)
Yes, that was our work schedule. I have since read many places that surgical masks, including during surgeries lasting longer are to changed every 4 hours. I also believe that was the time limit of our CBR masks too.
I now teach at med schools and long since not needed a respirator or a mask.
