Three of the biggest factors we measure for when testing indoor air quality are volatile organic compounds (VOCs), carbon dioxide, and formaldehyde. High levels of these contaminants can be dangerous to both productivity and health, and each is commonly found in buildings that are crowded, under construction, not up to code, or have recently had new furnishings installed. Click below to learn more about how we test for each, and why testing is so important for your health.

VOC Testing

You’ll likely hear this acronym used frequently by Hawk inspectors. VOCs, or volatile organic compounds, can accumulate as building materials emit gases. Because of their prominence and tendency to cause allergic reactions at high levels, we commonly incorporate this approach in testing plans.

CO2 Testing

If carbon dioxide is a natural atmospheric compound, why is it monitored during air quality testing? Excess CO2 can be a telltale sign of insufficient ventilation, and if we detect abnormal levels, it may be time to consider an air filter or other upgrade.

Formaldehyde testing

Formaldehyde falls into the VOC category, but because the EPA recognizes it as a carcinogen at high levels under long-term exposure, it deserves its own distinction. Though traces are present in urban areas with high concentrations of automobile exhaust, this VOC becomes airborne indoors when emitted from furnishings and building materials.
