Why Home Indoor Air Quality Matters?

In an age where the majority of our time is spent indoors, the quality of the air we breathe within the confines of our homes and workplaces is of paramount importance. Indoor Air Quality, or IAQ, serves as an invisible yet powerful determinant of our well-being. From everyday culprits like dust and chemicals to more insidious threats like asbestos and volatile organic compounds, our indoor environments have the potential to pollute the air we breathe.

In this article, let’s take a closer look at the critical facets of IAQ and its profound impact on human health.

How Poor Indoor Air Quality Impacts Our Health

The impact of poor indoor air quality (IAQ) on human health is an issue of growing concern. Individuals who spend the majority of their time indoors are exposed to a complex mixture of indoor air pollutants, which can have adverse health effects. One of the most notable connections between IAQ and health is its link to asthma.

Indoor spaces can become reservoirs for common indoor pollutants like fine particulate matter, dust, and volatile organic compounds. These pollutants, often originating from cleaning products and the burning of biomass, can have both short- and long-term health effects. According to the World Health Organization, exposure to indoor air pollution is responsible for millions of deaths worldwide.

Common Sources of Indoor Pollutants

Indoor air quality (IAQ) significantly impacts our well-being, and there are several sources of indoor pollutants to be aware of: 

  • Combustion-Related Pollutants: Carbon monoxide, nitrogen dioxide, and particulate matter are common culprits. These pollutants stem from various sources like cooking and heating appliances, fireplaces, candles, or tobacco smoke.
  • Household Products: Cleaning supplies and paints can emit harmful substances into the air. Pesticides used indoors often contribute to indoor pollution.
  • Radon: Radon is a naturally occurring radioactive gas that can infiltrate homes and become an indoor pollutant.
  • Biological Contaminants: Mold, dust mites, pet dander, and pollen are biological sources of indoor pollution. They can exacerbate respiratory problems, allergies, asthma, and can even lead to lung cancer and other illnesses.

Does Outdoor Air Impact Indoor Air?

Many factors, including outdoor air quality, influence indoor air quality (IAQ). Outdoor and indoor air interact through ventilation, infiltration, and natural airflow. Cooling and heating units, often reliant on outdoor air for ventilation, serve as conduits for the exchange between the exterior and interior environments.

To mitigate the impact of outdoor air pollution indoors, it is important to follow the indoor environmental quality (IEQ) guidelines from the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH). These guidelines help improve the occupational safety and health of workers by reducing exposure to indoor air pollutants and health hazards.

How to Maintain a Healthy Indoor Environment

Creating a healthy indoor environment is essential for your well-being. Here are some steps to help you achieve and maintain one:

  1. Proper Ventilation: Ensure good airflow by opening windows and using exhaust fans. Consider using an air purifier to filter out indoor pollutants.
  2. Control Humidity: Keep indoor humidity levels between 30-50% to prevent mold growth. Employ dehumidifiers in moist spaces, and address any leaks promptly to maintain a dry and healthy environment.
  3. Regular Cleaning: Regularly dust and vacuum your surroundings to eliminate allergens and dust mites. Additionally, sanitize frequently touched surfaces to curb the transmission of germs effectively.
  4. Avoid Smoking Indoors: Smoking indoors releases harmful chemicals and pollutants. Establish a strict no-smoking policy within your home.
  5. Limit VOC Exposure: Use low-VOC or VOC-free paints, adhesives, and cleaning products. Allow new furniture or carpeting to off-gas in a well-ventilated area before bringing them indoors.
  6. Address Allergens: Minimize pet dander by regularly grooming and cleaning your pets. Employ allergen-proof covers for mattresses and pillows to enhance your indoor air quality.
  7. Manage Pests Safely: Adopt eco-friendly pest control techniques and traps. Seal all entry points to block pests from invading your home, promoting a safe and pest-free environment.
  8. Store Chemicals Properly: Store chemicals, like cleaning products and pesticides, in a safe and well-ventilated area.
  9. Have Your HVAC Systems Checked Regularly: Maintain your heating, cooling, and ventilation systems to ensure they function efficiently. Change HVAC filters regularly.
  10. Monitor Your Indoor Air Quality: Consider using indoor air quality monitors to stay informed about pollutant levels. Act promptly if you notice any issues with IAQ.

By following these steps, you can create and maintain a healthier indoor environment, which will contribute to your overall well-being and quality of life.


The benefits of improving indoor air quality (IAQ) extend far beyond the immediate environment. It has a direct influence on your well-being and overall quality of life. By taking steps to enhance your indoor environment, you’re not only safeguarding against the adverse effects of poor IAQ but also investing in your overall well-being. Recognizing the connection between a healthier indoor environment and your well-being is the first step towards a brighter, healthier future.
