Unless it degraded the material, I'd disinfect anything that would be touching my face with rubbing alcohol. A filter would be better. I've not worn construction masks, but military style gas masks are absolute misery after a couple of hours because of the weight and the one-size-fits-all approach. A custom fit (because of the thermoplastic deformability) should make something this light weight far more comfortable for hours of use.
