Gas mask filter question

[James Green Dragon]

Can anyone tell me the shelf life of filters for the M-10 gas mask?

Thanks!

There should be a exp date printed on them.
If the seal is not broken the filters should be able to hold up 10+ years of shelve life

If not sealed, the life of the filter deepnds on the humidity in your area.

IIRC 6 months after opening is the general guidline.

I believe that the M10 is designed to be effective against tear gas and not much else.
