How often should airflow be checked for a PAPR system?

• A. Daily
• B. Weekly
• C. Monthly
• D. Before each use

Answer: (D)

Ensuring the PAPR delivers adequate airflow before every use is essential. PAPRs rely on a continuous flow to create positive pressure inside the hood, which helps keep contaminants out. If airflow drops—even briefly—because of a low battery, a kinked hose, a clogged filter, or a loose connection, protection can be compromised. A quick pre-use airflow check catches these issues right before you work, confirming the blower is running properly, the flow rate is within the required range, and there are no alarms. While daily, weekly, or monthly maintenance checks are still important for overall device care, they don’t guarantee safe performance at the moment you put the system on; a pre-use check ensures readiness for that specific use.
