When you think of air pollution, you probably envision smokestacks and cars spewing toxic fumes. But what about the air inside your home or business? Your indoor air quality can suffer pollution from the following five sources:

Carbon Monoxide

Carbon monoxide (CO) significantly affects indoor air quality through its non-irritating but highly toxic nature. CO emissions from unvented gas space heaters, gas stoves and improperly vented furnaces can easily build up in enclosed spaces, leading to potentially harmful concentrations. High levels of CO can cause headaches, dizziness, weakness, nausea and even death, making it a serious concern for IAQ.

Volatile Organic Compounds

Volatile organic compounds (VOCs) are a group of chemicals used in many household products, such as paint strippers and air fresheners. Some building materials, furnishings and office equipment can also produce VOCs. Exposure to high concentrations of VOCs can irritate the eyes, nose and throat, as well as headaches and dizziness.

Biological Pollutants

Biological pollutants, such as microbes, pollen, pet dander and dust mites, are allergens that can trigger an allergic reaction or asthma attack in people who are sensitive to them. If you notice that your family members suffer from allergies or asthma, it could be from the biological pollutants in the air.


Radon is a naturally occurring radioactive gas that is likely to enter homes and buildings through cracks in the foundation. They can accumulate to dangerous levels over time. Long-term exposure to radon increases your risk of lung cancer.

Pet Dander

Pet dander is microscopic pet hair and saliva particles that can linger in the air for hours. When inhaled, it can trigger an allergic reaction or asthma attack in people who are sensitive to them. To reduce the amount of pet dander in your indoor air, regularly clean your carpets, furniture and other surfaces where it can accumulate.
