Which component carries the contaminant to the air cleaner and then to the outside area?

• A. Inlet
• B. Duct
• C. Air Cleaner
• D. Outlet

Answer: (B)

The main idea is how air and contaminants travel through the system. The duct acts as the transport pathway that moves air from the source toward the air cleaner and, after filtration, toward the outside area. It connects the space, the filtration unit, and the exhaust, so the contaminated air is carried into the air cleaner where contaminants are removed, and then the cleaned air is pushed out to the outside through the duct network. The inlet is just the entry point for air, the air cleaner performs filtration, and the outlet is where cleaned air leaves; none of these by themselves transport the contaminant from the source to the cleaner and then to outside as effectively as the duct does.
