What does HEPA stand for?

• A. High Efficiency Particulate Air
• B. Heavy Equipment Particulate Air
• C. High Efficiency Particulate Atmosphere
• D. High Efficiency Particle Air

Answer: (A)

This question tests your knowledge of what HEPA stands for and the type of filtration it represents. HEPA stands for High Efficiency Particulate Air. This means a filter that is very effective at trapping tiny particles from the air—typically at least 99.97% of particles around 0.3 microns in diameter. In lead inspection and abatement, using HEPA equipment helps prevent dust from spreading during cleanup and sampling, which is why this term is important. The other options mix up the wording: they either say "Equipment" instead of the filter’s purpose, use "Atmosphere" instead of "Air," or use the singular "Particle" instead of the standard "Particulate."
