Information on how long Gas Mask/Respirator filters last.
Gas mask filters are often given best before/expiry dates of about 5-15 years depending on the filter. Filters will last longer than this when sealed properly but the amount of time is unknown.
Once a filter is open depending on what the filter medium is exposed to will affect how long the filter lasts.
The size of the filter will also make a big difference, Russian EO-14, and EO-16 canister/coffee can filters will last far longer than compact filters designed to be light-weight and mount to the side of a gas mask.
The internal components of a filter will affect the lifespan as well, for example, a filter with a chromium layer will last longer than a filter without chromium that relies on activated charcoal alone.
Lastly, particulate filters have an independent lifespan from carbon inside the filters.
