MSA Organic Vapor cartridges are available for the Advantage® Series Respirators. When properly fitted these cartridges protect against Organic Vapors. The addition of a P100 prefilter adds protection against all particulates. Filter cartridges protect against dusts, particles and mists. Chemical Cartridges protect against gases and vapors. Combination cartridges deliver protecton from both particulate and gaseous contaminants. This cartridge does not provide protection against all possible contaminants. Although it is designed to remove many different contaminants, the protection provided by this cartridge is limited to those specific contaminants and classes of contaminants identified in the product literature. Before use, read all instructions and ensure that all contaminants present can be removed by this cartridge. Failure to do so can result in serious personal injury or death.
