• Best For: Crews needing HEPA-level filtration in a compact 6-quart Sandia Raven backpack vacuum for hallways, commercial spaces, and allergen-sensitive accounts.
• Highlight: The Sandia HEPA Raven captures fine particulate through full HEPA filtration, including a HEPA bag and HEPA filter, in a lightweight 6-quart backpack worn on the back.
• Expert Note: The 6-quart HEPA Raven trades a little capacity for maneuverability; it is a strong pick for healthcare, labs, and schools where exhaust air quality is the priority.
