Occupationally I'm a diesel mechanic,so I suppose I could be lumped into the non occupational rocket scientist category. Im learning python.

Yes, we wear n95, but we also get OSHA/niosh specific training on fitment, changing, PPE exposure limit, and appropriate environments. You do not. What people are hoping is that an industrial particulate mask is going to somehow prevent the flu or corona, which honestly I have never understood. Wearing a mask while pressure cleaning a paccar12 engine? Yes, you don't want fine grease mist in your lungs. Powder coating something? Better mask up. Wearing it for a fire? Yes, but change it out once or twice a day and check it often. The flu? How?

I used to be a residential painter. AIUI (and I could be wrong here) biological and water-based molecules are larger than other chemical molecules so can be stopped by the particulate mask. This is why you can wear a dust-cup when spraying with acrylic (water-based), but need a respirator for oil or lacquer-based paint. TBH I'd expect the n95 to work better for infection than a surgical mask because you can get a better seal to your face
