HEPA stands for?

• A. High Efficiency Particulate Air
• B. High Efficiency Particulate Aerosol
• C. Heavy Efficiency Particulate Air
• D. High Energy Particulate Air

Answer: (A)

HEPA describes a filter designed to trap very small particles from the air. The acronym stands for High Efficiency Particulate Air, which communicates both the high capture efficiency and that it targets particulates in the air being filtered. In practice, true HEPA filters capture at least 99.97% of particles as small as 0.3 microns, a standard used to ensure effectiveness against common dust and lead-containing particles encountered during cleanups. The other options use terms that don’t match the established name: Aerosol instead of Air, or Heavy and High Energy, which aren’t used to describe HEPA filters.
