ULPA stands for

ULPA stands for

• A. Ultra-Low Particulate Air filter
• B. High Efficiency Particulate Air filter
• C. Containment Secondary Engineering Control
• D. Containment Segregated Compounding Area

Answer: (A)

ULPA stands for Ultra-Low Particulate Air filter. This designation signals a filter designed to capture extremely small particles with very high efficiency, more than standard HEPA filtering. While HEPA (High-Efficiency Particulate Air) is commonly used in containment devices for hazardous drug handling, ULPA represents an even stricter level of filtration. The key idea is that the acronym itself spells out the exact meaning: Ultra-Low Particulate Air filter. The other terms describe either a different filtration standard (HEPA) or refer to containment spaces rather than the filtration device itself, so they don’t fit the expansion of ULPA.
