Usage recommendations

Use only with compatible 3M cartridges and filters selected for the identified hazard. Ensure fit testing where required and replace filters or cartridges according to exposure, breathing resistance, or manufacturer instructions. Do not use in atmospheres that are immediately dangerous to life or health unless the selected cartridge is rated for that hazard and organizational procedures permit such use.
