What term describes a metal coil covered with a lightweight fabric that attaches to a HEPA machine?

• A. Firestop System
• B. Fire Wall
• C. Flex Duct
• D. Fungi

Answer: (C)

A flexible duct describes a duct assembly built around a spiraled metal core (the coil) that is wrapped with a lightweight fabric or jacket. This construction creates a lightweight, bendable conduit that easily attaches to a portable HEPA filtration unit and routes air to or from a space. In infection control, flexible ducting is commonly used to connect HEPA machines to rooms or exhaust points because it allows quick, adaptable setup without rigid piping, while still maintaining effective filtration. The other terms refer to completely different concepts: a firestop system and a fire wall relate to fire resistance and separation, while fungi are microorganisms and not a type of ducting or attachment for HEPA equipment.
