3M™ Particulate Filter 2138, GP2/GP3 provides protection against particulates (P2/P3*), Ozone and Nuisance Level** Acid Gas & Organic Vapours with Low Vapour Pressure. *Higher P3 protection factors only achieved with a 3M Full Face Respirator, otherwise P2 protection level when worn on a 3M Half Face Respirator. **Nuisance Levels are those levels below the Workplace Exposure Standard (WES).

Note that any filtering respirator should not be used for protection at airborne concentrations of contaminants above the relevant Immediately Dangerous to Life or Health (IDLH) levels. This cartridge/filter, when used for protection against the contaminants as specified, is capable of providing the following protection levels:

• With a 3M 6000/7500 Series Half Face Respirator: for particles, for airborne concentrations up to 10 times the Workplace Exposure Standard (WES)
• With a 3M 6000/7800 Series Full Face Respirator: for particles, for airborne concentrations up to 100 x WES
• Organic compounds with low vapour pressures (<1.3Pa @ 25 degrees Celsius) in concentrations up to 10 x WES
• Ozone up to 10 x WES
• Offers relief from acid gases and organic vapours at levels below the WES.
