Which statement best describes VOCs under 62.1?

• A. VOCs are not addressed by 62.1.
• B. VOCs are addressed by filtration and source control.
• C. VOCs are addressed only by humidity control.
• D. VOCs are addressed solely by increasing outdoor air.

Answer: (B)

VOCs are tackled in 62.1 through two main approaches: source control and filtration. Source control means reducing or eliminating VOC emissions at the source—using low-VOC paints, adhesives, cleaners, and furnishings, so fewer contaminants enter the space to begin with. Filtration refers to removing what’s already in the air or attached to particles, and it can include specialized filters (such as activated carbon) that adsorb VOCs as air passes through the HVAC system. Ventilation (bringing in outdoor air) helps dilute VOCs, but it’s not the sole method and can be insufficient on its own. Humidity control mainly affects moisture-related issues rather than VOC concentrations. So the statement that best describes VOCs under 62.1 is that they are addressed by filtration and source control.
