#M50 gas mask filter life how to
Just FYIĮxactly, if you are relying on CBRNE PPE to save your life you best know how to maintain it and validate a good test fit.

Varies A LOT with type of filter and usage.ĥ. See #2 Most do not protect against things as people think they do.Ĥ. Some have 'shelf lives' even if never used, even if sealed in a package especially if the packing is opened.ģ. especially any 'flapper' valves, you may need to learn about those.Ģ. You need to know that the 'rubber' deteriorates over time or heat, sun, etc.
#M50 gas mask filter life full
Reusable 3M Respirators, full face vs half face. M40 Gas Mask, Dod just replaced them with the M50 so alot of surplus floating around.Īvon which makes the M50 also makes a style with screw on filters, called the C50. 3m, Scott, MSA, Draeger, North, Honeywell, Survivair come to mind. I would suggest limiting your choices to known, established international industrial safety manufacturers. They are cheaper, lighter and easier to breathe through. If you're not interested in general survival/chemical protection and strictly worried about riot control agents, all you need are P100 filters.
