Indoor air quality management through ventilation and filtration

Indoor air quality is influenced by a variety of pollutants that can accumulate in homes, schools, and workplaces. These contaminants generally fall into three categories: particles (such as dust, pollen, pet dander, and smoke), biological contaminants (including mold spores and bacteria), and gases or chemical pollutants (such as radon, carbon monoxide, and volatile organic compounds).

Effective management of indoor air requires a combination of source control, ventilation, and filtration. While portable air purifiers can reduce airborne particles, they are not a substitute for addressing underlying issues like moisture, radon, or carbon monoxide. Common mitigation strategies include using properly vented range hoods, maintaining fuel-burning appliances, fixing leaks to prevent mold, and ensuring adequate ventilation when using cleaning products or paints. For older buildings, special care should be taken during renovations to avoid disturbing hazardous materials like lead dust or asbestos.
