Particulate matter (PM2.5 and PM10) from cooking, candles, smoke and HVAC systems Chemical vapors (VOCs) from paints, cleaners, new flooring and furniture Carbon dioxide and carbon monoxide, which point to ventilation and combustion problems Temperature and relative humidity; sustained humidity above 60 percent is a warning sign Radon (optional), measured against the EPA action level of 4.0 pCi/L When should Chesterfield homeowners test indoor air quality?

These are the situations and Chesterfield home types where a test pays off: Allergy or respiratory symptoms that ease when you leave the house After a renovation, new flooring or new furniture Humidity that stays high, or a musty smell from a basement or crawl space Before buying or selling a home Two-story and walkout-basement homes in the subdivisions off Clarkson Road and Olive Boulevard Homes in the older parts of Chesterfield built before the city incorporated in 1988 How does indoor air quality testing work in Chesterfield?
