| I have a ton of P100, 7093C- HF/P100, and 60923 OV/AG P100 filters. In a pinch I will use these. But, anyone else have expired ones and still use. I know the old NATO NBC filters are not good to use if old. Thinking of what to do with totes of these. |
I survived the cockpocalypse of 11/21/2012.

| I used to work for 3M in the division selling these. I have many also. I would NOT recommend them for industrial use at all. However, for personal emergencies, if they’ve been stored in original packaging in climate controlled environments, I personally would not have any hesitancy to use. I do not speak for 3M any longer and this is not professional advice! |

I painted my truck this past weekend using 3M organic vapor/P100 cartridges that expired in February of 2020 and didn't smell any solvent breakthrough. YMMV. Edit to add: The cartridges were stored in their original unopened packaging in a semi-climate controlled environment (garage in SE Texas with a window unit AC that keeps temps in the low 80's in the summer but no heat in winter.) |
