What Do Indoor Air Quality Monitors Test For? (And Does It Include Radon?)
Understanding the difference between consumer air monitors and professional environmental testing for Metro Atlanta homes.
As awareness around home health increases, more homeowners in Gwinnett, DeKalb, and Fulton counties are asking: "What do indoor air quality monitors actually test for?"
Whether you are buying a consumer-grade monitor off the shelf or hiring an environmental specialist to assess your home, it is critical to understand what is being measured—and more importantly, what is being missed.
What Do Standard Indoor Air Quality Monitors Test For?
Off-the-shelf indoor air quality monitors use basic sensors to track the most common pollutants. These standard devices typically measure:
- Particulate Matter (PM2.5 and PM10):These are tiny particles of dust, soot, and smoke. While a monitor can tell you the amount of particulate matter is high, it cannot tell you what the particles are (e.g., harmless dust vs. toxic black mold spores).
- Volatile Organic Compounds (VOCs):Chemical gases emitted by paints, cleaning supplies, new furniture, and building materials.
- Carbon Dioxide (CO2):High CO2 levels indicate poor ventilation and stale air.
- Humidity and Temperature:Crucial metrics, as high humidity directly fuels mold growth and dust mite populations.
Does Indoor Air Quality Testing Include Radon?
No, standard indoor air quality testing does not automatically include radon.
This is one of the most dangerous misconceptions for homeowners. Many people purchase an expensive "smart" consumer air monitor (like Airthings or Awair) and assume their home is perfectly safe because the light is green. However, radon is a naturally occurring radioactive gas that requires completely different sensor technology to detect.
Because radon gas seeps up from the granite bedrock common in Georgia (especially in DeKalb and Gwinnett counties), it bypasses standard air filters and PM2.5 sensors entirely. Radon is the second leading cause of lung cancer in the United States, and it is completely invisible, odorless, and tasteless.
To test for radon accurately, especially for real estate transactions, you must use a dedicated professional-grade continuous radon monitor. For example, consumer monitors like Airthings can take weeks to average out a reading and lack tamper-resistance. We use Professional-Grade Breeze Environmental Monitors. These devices are annually calibrated, highly sensitive, and feature built-in tamper-resistance (logging if the device is moved or loses power). This ensures our 48-hour short-term tests provide fast, highly accurate, and legally defensible data that is accepted by real estate agents, attorneys, and insurance adjusters.
The Professional Difference: True Environmental Diagnostics
While a DIY monitor acts like a "check engine" light, a professional assessment acts like the mechanic's diagnostic computer. At Micro Clean Restoration, our comprehensive Indoor Air Quality (IAQ) testing utilizes laboratory analysis to provide a detailed breakdown of the exact particles in your air.
Instead of just telling you "particulates are high," we tell you exactly what those particulates are—whether it's Stachybotrys (black mold), pet dander, fiberglass from deteriorating ductwork, or insect fragments. Furthermore, we always recommend pairing our IAQ tests with our dedicated Radon Testing to ensure your entire home ecosystem is truly safe.
When Should You Call a Professional?
You should schedule a professional, whole-home environmental assessment if:
- You are experiencing unexplained chronic allergies, headaches, or respiratory issues.
- Your DIY air monitor consistently shows poor air quality, but you don't know the source.
- You notice a persistent musty odor in your home or crawlspace.
- You are preparing to buy or sell a home in Metro Atlanta.
- You have never tested your home for radon.
Micro Clean Restoration is Metro Atlanta's authority on whole-home environmental health. We don't just treat symptoms; we diagnose the root cause, providing clarity, documentation, and permanent solutions.
