These are expired CBRN canisters made by MSA. Originally, this filter (P/N 10046590) would allow for MSA respirators (or any other 40mm respirators) to gain NIOSH CBRN Standard (TC-14G-0254) by effectively removing harmful gasses, vapors and particulates so that the user can confidently breathe safely.

The sealed filters are expired so we can't guarantee these filters against chemical weapons due to oxidation of the internal filler. However, the P100 particulate filter is still good. Unlike the chemical warfare countermeasures the P100 component is just a HEPA filter. It doesn't stop working until you clog it with trapped particulate. In essence, this is just a heavier, cheaper P100 filter. With a bonus roll for chemical resistance.
