Indoor air quality, renovation dust, or symptoms at home
Stuffy air, new-construction or renovation fumes, or unexplained symptoms.
Indoor air monitors track particulates (PM2.5), carbon dioxide, VOCs, and formaldehyde over time, which helps connect symptoms to conditions. Radon is a separate, invisible risk worth its own test, especially in lower levels of the home.
What to do
- Use an indoor air quality monitor for VOCs, formaldehyde, PM2.5, and CO2.
- Test for radon separately. Air-quality monitors do not measure it.
- Address sources such as ventilation and off-gassing materials once you have data.
Where to go next
General information to help you find the right test and an accredited lab. This is not medical, legal, or safety advice. For a confirmed exposure or a health concern, talk to a qualified professional, and always confirm a lab's current accreditation with the certifying body.
