How must filters be identified?

• A. Labeled and color-coded with approved NIOSH labels
• B. Identified by part number only
• C. No labeling required
• D. Color-coded but not labeled

Answer: (A)

Filters must be clearly identified with approved NIOSH markings, and they should be color-coded to indicate the type of filter and its hazard protection. This combination lets you verify that a filter is officially approved for use with the respirator and for the specific conditions you’re protecting against, while the color cues help you distinguish between different cartridge or canister types at a glance. The official labeling (including the NIOSH approval number) provides traceability and confirms compliance with safety standards, which is essential for protection, regulatory compliance, and proper maintenance. Relying on a part number alone doesn’t prove NIOSH approval, and using filters with no labeling is unsafe and noncompliant. Color-coding without labeling can be confusing or misleading if labels wear off or if different manufacturers use similar colors.
