Which item is NOT a typical IAQP component?

• A. Ventilation
• B. Filtration
• C. Source control
• D. Noise mitigation strategies in ductwork

Answer: (D)

The main idea is that IAQP components are focused on controlling indoor contaminants through three main avenues: source control, ventilation to dilute contaminants, and filtration or air cleaning to remove them. Source control means preventing or reducing emissions at the source, such as using low-emitting materials or proper storage of chemicals. Ventilation provides outdoor air to dilute indoor pollutants, and filtration captures particulates from the air. Noise mitigation strategies in ductwork, while important for comfort and system performance, do not affect contaminant concentrations and therefore aren’t considered part of IAQP’s typical components.
