3M 7503 LARGE HALF FACEPIECE ULTIMATE REUSABLE

There was little indication of the size of this mask which is manufactured in small, medium, and large sizes. I had tried on a medium at a local hardware store and it was too small (the bottom of the mask did not go under my chin) and it was the only size they carried. So, I ordered this mask based on the faint "L" on the black nosepiece of the mask. It is indeed the large version of this mask that I received and it fits my male face (I'm 5'8" and have what I'd call a normal size head.) quite well. I haven't tried it yet except to see how easy it is to breathe with the pink particle filters attached. Breathing is easy and the mask felt comfortable (soft silicone). I like that exhaled air is directed downward where it will not fog goggles or glasses.
