MSA shelf life and change-out statements
Shelf Life of Filter Cartridges: All particulate-only cartridges and filters have an unlimited shelf life. This includes Flexi-Filters, Comfo and Advantage style P100 cartridges. Also, Type HE PAPR cartridges that are particulate-only have unlimited shelf life. These include Optifilter and OptimairTL Type HE cartridges. Chemical and Combination cartridges for all APR have a recommended shelf life of 3 years. Please note that these cartridges do not have an "expiration date" printed on them. PAPR combination cartridges, gas mask canisters, including industrial gas masks, CBRN and Riot control canisters have an expiration date printed on the cartridge label. Generally these are 5 year expiration. While the P100 or particulate performance efficacy of these types of canisters may remain intact following expiration, MSA cannot advocate use beyond the expiration date.
Riot Control Canisters, CBRN Canisters, and Combination Chemical/Particulate Respirator Cartridges (GMA-P100, GMB-P100, GMC-P100, GMD-P100, GME-P100, GMF-P100 and GMI-P100) generally are limited use cartridges and have required changeout schedules.
