HEPA stands for the term used in asbestos control. Which is the correct full form?

Explanation:
HEPA stands for High Efficiency Particulate Air. This expansion describes filters that are designed to remove very small airborne particles, which is essential in asbestos work to prevent fibers from becoming airborne. In practice, HEPA filters capture at least 99.97% of particles about 0.3 microns in size, making containment and worker protection effective. The parenthetical “(absolute)” isn’t part of the official expansion, though some contexts use “HEPA Absolute” to emphasize the high efficiency; the standard form remains High Efficiency Particulate Air. The other phrasings mix up the words and don’t reflect the true acronym used in asbestos control.
