Indoor air quality (IAQ) is an important aspect of maintaining a healthy living and working environment. It's essential to test your indoor air quality regularly to ensure that your living and working space is safe and healthy. Here's what to know about indoor air quality testing

Temperature and Humidity 

High humidity levels can promote the growth of mold, mildew, and bacteria, which can cause respiratory problems. Mold and mildew can also cause damage to books, wood furniture, and walls.

Carbon Dioxide (CO2)

Carbon dioxide is a colorless and odorless gas that is produced by human respiration and combustion processes. High levels of CO2 in indoor air can cause headaches, dizziness, and nausea. Testing for carbon dioxide levels can help you determine if there is adequate ventilation in your living or working space.

Carbon Monoxide (CO)

Carbon monoxide is a poisonous gas that is produced by combustion processes such as burning fuel, including gas, oil, and wood. High levels of carbon monoxide in indoor air can cause headaches, dizziness, nausea, and even death. Testing for carbon monoxide levels is critical, particularly in living spaces with gas or wood-burning appliances.

Volatile Organic Compounds (VOCs)

Volatile organic compounds are chemicals that are released from building materials, cleaning products, and personal care products. High levels of VOCs in indoor air can cause respiratory problems, headaches, dizziness, and other health issues.

Running tests for VOCs can help identify the source of the problem, and determine if changes are needed to improve indoor air quality.

Particulate Matter (PM)

Particulate matter is a mixture of liquid droplets and small particles that are present in the air. These particles can be made up of dust, pollen, mold spores, and other contaminants. 

High levels of PM can cause respiratory problems and other health issues. Testing for PM levels can help determine whether these are the cause of any respiratory symptoms.


Radon is a colorless and odorless gas that is produced by the natural decay of uranium in soil, rock, and water. High levels of radon in indoor air can cause lung cancer, particularly in people who smoke. Radon tests should be run in areas with a high concentration of uranium in the soil.

Contact a service provider near you to learn more about indoor air quality testing. The results gathered from these types of testing can give you a good idea as a homeowner of how to move forward.
