Indoor Air Quality in Chesterfield, MO

Indoor air quality in Chesterfield, MO is measured, not guessed. Air Sense Environmental runs a continuous monitor in the home for 48 hours or more, tracking particulate matter, VOCs, carbon dioxide, carbon monoxide and humidity, and the St. Louis County homeowner gets a written report and a plan.

What does an indoor air quality test measure in a Chesterfield home?

• 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?

Chesterfield splits into two very different foundations: the Chesterfield Valley, the Missouri River floodplain once called Gumbo Flats, with deep silty soil, and the hills above it where 1970s to 1990s subdivisions sit on clay over bedrock. 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?

1. Monitor placement. One or more continuous monitors go in the rooms where the family spends its time.
2. 48 hours of data. Readings are logged at one-minute intervals through normal daily life.
3. Written report. You see each pollutant against its healthy range, with the specific fix for anything outside it.

What happens after the indoor air quality results?

The report names the problem, and Air Sense Environmental installs the fix it calls for: an AprilAire whole-home dehumidifier for high humidity, an energy recovery ventilator for stale air and rising CO2, or a radon mitigation system when radon is at or above 4.0 pCi/L. The main indoor air quality testing page covers the equipment and the full process.

How much does indoor air quality testing cost in Chesterfield, MO?
