What are the common pollutants found in indoor air?

Indoor air quality is crucial for maintaining a healthy and comfortable living environment, as people spend the majority of their time indoors. According to the EPA, here are the typical pollutants found in indoor air and their sources:

  1. Combustion Byproducts: These include carbon monoxide (CO) and particulate matter, which can be emitted from sources such as tobacco smoke, wood and coal heating appliances, cooking stoves, and fireplaces.
  2. Substances of Natural Origin: Pollutants like radon, pet dander, and mold can originate naturally within indoor environments. Radon, a radioactive gas, can seep into buildings through cracks in the foundation. Pet dander and mold spores are common allergens found indoors, especially in poorly ventilated areas.
  3. Biological Agents: Mold, bacteria, and viruses can proliferate in damp or humid indoor environments, leading to respiratory issues and allergies.
  4. Chemical Contaminants: Cleaning supplies, paints, insecticides, and other household products can introduce volatile organic compounds (VOCs) into the indoor air. These chemicals can off-gas and contribute to poor air quality, especially in poorly ventilated spaces.
  5. Building Materials: Some pollutants originate from building materials themselves. For example, asbestos fibers can be released from deteriorating insulation, while pressed wood products may emit formaldehyde and other harmful chemicals through off-gassing.
  6. Outdoor Sources: Outdoor air pollutants, such as smoke, vehicle emissions, and industrial pollutants, can infiltrate indoor environments through open doors, windows, and ventilation systems. Radon gas can also enter buildings from the surrounding soil.

Other factors affecting indoor air quality include the air exchange rate, outdoor climate, weather conditions, and occupant behavior. Proper ventilation, air filtration, and maintenance of HVAC systems are essential for controlling indoor air pollutants and ensuring a healthy indoor environment.
