MSA 815365 Combination Cartridge/Filter Advantage Bayonet Green

MSA Advantage Bayonet Cartridge/Filter

This MSA Advantage bayonet combination cartridge and filter protects against ammonia, methylamine and particulates with a P100 rating. It fits MSA 1000, 3000 and 4000 series respirators plus Advantage 200 LS and 420 models. The green and magenta colour coding identifies the specific hazard coverage at a glance. Each pack contains two units for immediate replacement or spares.

Bayonet Connection and Installation

The bayonet connection twists onto compatible MSA facepieces without tools, locking with an audible click that confirms a secure seal. Users must verify the respirator series matches the listed Advantage, 1000, 3000 or 4000 families before fitting. A common error is forcing the cartridge onto an incompatible bayonet pattern, which prevents proper seating and compromises protection. Always perform a user seal check after installation.

Sustained Use Performance

Under continuous exposure the P100 filter media maintains its particulate efficiency while the chemical sorbent bed adsorbs ammonia and methylamine until breakthrough. Service life depends on contaminant concentration, humidity and work rate rather than a fixed time limit. The cartridge is not suited for environments requiring protection against gases outside the AM/MA designation or for oxygen-deficient atmospheres. Workers needing broader gas coverage or higher capacity cartridges must select a different filter type.
