Which statement about HEPA/P100 filters is true?

• A. To strengthen the strap.
• B. To trap asbestos fibers effectively.
• C. To increase airflow.
• D. To reduce heat.

Answer: (B)

HEPA and P100 filters are made to block tiny airborne particles, including asbestos fibers, to protect the wearer from inhalation. They achieve very high filtration efficiency, capturing the vast majority of particles as small as 0.3 microns, which is essential for asbestos safety. That’s why the statement that these filters trap asbestos fibers effectively is true. The other options miss the core purpose: the filter doesn’t strengthen the strap, it’s not about increasing airflow, and it doesn’t reduce heat—the filter’s role is to protect by filtration.
