RESPIRATOR CARTRIDGE AND FILTER COLOR DESIGNATIONS<br />
Color-coded cartridges are available for a variety of air contaminants. In addition to the color-code<br />
convention, the specific contaminant groups are printed on the side of the cartridge or filter. The<br />
most common cartridge and filter colors are described here:<br />
• HEPA or P100 Filter (Magenta): For filtration of particulates, including asbestos, lead, and<br />
silica. The “P” indicates the filter media is “oil-Proof”, and the “100” indicates the filter<br />
efficiency is 99.97% of particles at the 0.3 micron size. “Magenta” color may range from<br />
pink to purple<br />
• Organic Vapor Cartridge (Black): For certain organic vapors. IH will determine service<br />
life based on the specific contaminants when respirators are mandatory for employee<br />
protection<br />
• Acid Gas Cartridges (White): For use in atmospheres with acid gas, such as chlorine,<br />
hydrogen chloride, sulfur dioxide, hydrogen fluoride<br />
• Organic Vapor and Acid Gas Combination Cartridge (Yellow): For use in atmospheres<br />
with organic vapors and acid gas in combination, or atmospheres with either organic vapors<br />
or acid gas<br />
• Mercury Vapor and Chlorine Gas Cartridge (Orange or olive): Useful for protection<br />
against mercury vapor and chlorine gas<br />
• Multi Contaminant (Olive): For multiple contaminant types. This can include certain<br />
organic vapors, acid gases, formaldehyde, ammonia, and methylamine. Olive may be used<br />
for other cartridges such as mercury/chlorine. Care should be taken to check the side of the<br />
cartridge to verify its approved use<br />
