The term HEPA means:

The term HEPA means:

• A. High Efficiency Particulate Air (absolute)
• B. Health Environment Particulate Air
• C. Heavy Emission Particulate Air
• D. High Efficiency Particulate Absorber

Answer: (A)

HEPA is a type of air filter that removes a very large share of tiny particles from the air, which is essential in asbestos work to prevent fiber release. The acronym stands for High Efficiency Particulate Air, reflecting its purpose of delivering clean air by trapping most particles as air passes through the filter. In practical terms, HEPA filters must trap at least 99.97% of particles about 0.3 microns in size, making them highly effective for capturing asbestos fibers. The other wording in the options isn’t correct: it doesn’t use absorber, and “Health Environment” or “Heavy Emission” don’t reflect the filter’s name. The term “absolute” sometimes appears to emphasize high efficiency, but the official name is High Efficiency Particulate Air.
