Indoor Air Quality: Improve Your Home & Office Air Now

Introduction: Understanding Indoor Air Quality (IAQ)

What is Indoor Air Quality and Why Does it Matter?

Indoor Air Quality (IAQ) refers to the condition of the air inside buildings, including homes, offices, schools, and industrial spaces. The presence of pollutants, ventilation efficiency, humidity levels, and air exchange rates determine IAQ. According to the Environmental Protection Agency (EPA), indoor air can be 2-5 times more polluted than outdoor air, making it a significant concern for human health.

"Indoor air pollution is an invisible but formidable enemy that affects millions globally." – WHO

Primary Sources of Indoor Air Pollution

Several factors contribute to deteriorating IAQ, including:

Particulate Matter (PM): Dust, pollen, pet dander, and fine particles from combustion sources.

Volatile Organic Compounds (VOCs): Emissions from paints, furniture, and cleaning agents.

Carbon Dioxide (CO₂): Poor ventilation leads to CO₂ buildup, affecting cognitive function.

Biological Contaminants: Mold, bacteria, and viruses thrive in humid environments.

Chemical Pollutants: Tobacco smoke, formaldehyde, and nitrogen dioxide from cooking and heating appliances.

How Poor IAQ Impacts Human Health

Long-term exposure to poor indoor air quality can lead to severe health issues. Scientific studies highlight the following effects:

✅ Respiratory Problems: Chronic exposure to PM and VOCs is linked to asthma, bronchitis, and lung infections. ✅ Cardiovascular Issues: Fine particulate matter (PM2.5 and PM10) can penetrate deep into the bloodstream, increasing the risk of hypertension and heart diseases. ✅ Cognitive Decline: High CO₂ levels impair concentration, memory, and productivity. ✅ Immune System Weakening: Continuous inhalation of pollutants weakens immune defenses, making individuals prone to infections.

Key Indoor Pollutants and Their Health Risks

Below is a comprehensive table outlining common indoor pollutants, their sources, and associated health effects:
