These are expired riot control canisters made by MSA. Originally, this filter (P/N 817590) would allow for the MSA Advantage series of respirators to gain NIOSH approval for CS, Chrlorobenzylidene Malononitrile, CN, Chloroacetophenone and all particulate aerosols including oil based aerosols.
The sealed filters are expired and the out-of-bag filters we can't guarantee for any other purpose besides training or display as all the filtering properties are, well, expired. These make great placeholders for display or LARP/Airsoft use, and if you're not dealing with literal chemical warfare tier gas & dust could be incredibly handy to have for projects around the house. That said, please exercise caution and consider buying new, unexpired filters for usage around more dangerous-to-inhale materials such as Asbestos.
Many of these will have an intact P100 filter as those don't have chemical properties that would make them expire. Even if you're not paranoid about COVID 2™ somehow appearing, A P100 filter is extremely handy for a long time, and only stops working once it gets clogged.
- Compatible with all MSA Advantage series respirators that accept bayonet style filters
- For display or training purposes only
- Not compatible with NATO style gas masks without an adapter - please note that even with a new filter, many of these DIY adapters may have an improper seal!
New In Sealed Packaging: Filter is in the original MSA sealed foil packaging.
Excellent: Filter is outside of the original MSA packaging, any use of the filter is unknown. Given the state of the gas masks in this shipment, we're guessing these filters were seldom used if ever.
