3M Face Mask - P100 Particulate Respirator

A 3M P100 particulate respirator face mask, model 8293, NIOSH TC-84A-2561, with cool flow valve.

 

Dust masks are rated with a letter (N means not oil resistant, R means resistant to oil, and P means oil proof); and a number (95%, 99%, or 100% particulate removal). For example, N95 masks are not oil resistant and remove 95% of particles at least 0.3 microns in diameter size.
