Air Quality #6: New Respirator

I have the 3M 7500 series as well. It’s amazing how comfortable it is.

#Notw—-not a question I can answer yet. I think Marc Spagnuolo or CharlesA might be able to give you a better answer as I’ve just recently purchased mine based upon Marc’s advocacy of the product. All I can tell you right now is the fit and no fog to my glasses is awesome

People get me and Marc Spagnuolo mixed up all the time . . .

anyway, I change them when I see a build-up on the outside of the pink filters. I’m not a daily user of the mask, so I’m not too concerned with throwing them out early.
