What is a combination cartridge?

• A. Made of both Chemical cartridge and particulate filter
• B. Made of chemical cartridge only
• C. Particulate filter only
• D. A cartridge designed for gas-phase filtration

Answer: (A)

A combination cartridge is designed to handle more than one type of contaminant in a single unit by pairing a chemical (gas/vapor) filtration component with a particulate filter. This means it can remove gases or vapors and also trap airborne particles without needing separate parts. It’s particularly useful in environments where both hazards are present, offering simpler gear and reducing the chance of using incompatible components. When using this type, you still need to verify the specific chemicals and particle performance (and that the cartridge is compatible with your respirator) because different agents require different sorbents and some combinations have limited protection for certain substances. This is not just a gas-phase cartridge or just a particulate filter; its defining feature is the integrated filtration of both types in one cartridge.
