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

  1. Use an indoor air quality monitor for VOCs, formaldehyde, PM2.5, and CO2.
  2. Test for radon separately. Air-quality monitors do not measure it.
  3. Address sources such as ventilation and off-gassing materials once you have data.

Common questions

What does an indoor air quality monitor measure?

Most track particulates (PM2.5), carbon dioxide, VOCs, and sometimes formaldehyde over time, which helps connect symptoms to conditions in the home.

Do indoor air quality monitors detect radon?

No. Radon needs its own dedicated test or monitor. Standard indoor air quality monitors do not measure it.

How do I improve indoor air once I have data?

Address the source. That usually means better ventilation, controlling humidity, and reducing off-gassing materials, rather than only filtering.
