Expired Scott cartridges

I have a few of these:

Still sealed I the foil.
Are they ok for particulate/CS/training? Do they “go toxic” like I have read about some filters?
I’m not expecting my older Scott masks or these filters to save me from sarin gas. Just don’t want to slap one on and get sick.

They should be ok. Even if the activated charcoal is too old, the construction of the filter should still protect against particulates which is what CS/CN is.

Interesting. I have 3 or 4 that are expired too.
