Respirator Cartridge Recall
SAFETY NOTICE: Comfo® Air-Purifying Respirator Cartridges
MSA recently determined that a small percentage of Comfo Combination Cartridges, manufactured from September 1, 2016 through December 11, 2016, may not comply with the NIOSH required P100 filter minimum efficiency level of 99.97% for particulates. The affected cartridges types are listed below:
Our investigation confirmed that the reduced efficiency is due to leakage caused by separation of the adhesive used to bond the P100 filter component to the cartridge body. The adhesive separation was found to occur after final production and testing. Since this condition is internal to the cartridge assembly, it is not detectable by the user during normal respirator inspections or seal checks.
As a result of this condition, MSA requests that you immediately remove from service all affected cartridges indicated above that were manufactured during the specified time period. MSA has corrected this condition and will replace affected cartridges free of charge.
