Air pollution is no longer limited to metro cities. Even tier-2 towns are facing rising levels of dust, vehicle emissions, smoke, and construction pollution. Poor air quality affects children, elders, and even healthy adults. The good news? You can easily monitor and improve the air quality inside your home.
What Is Air Quality and Why It Matters
Air quality is measured using the Air Quality Index (AQI). Lower AQI = cleaner air. Higher AQI = unhealthy air.
- 0–50: Good
- 50–100: Moderate
- 100–150: Unhealthy for sensitive people
- 150+: Harmful for everyone
Common Pollutants in Indian Cities
| Pollutant | Source | Health Impact | Common Scenario |
|---|---|---|---|
| PM2.5 | Vehicles, industry, crop burning | Asthma, fatigue, lung issues | Winter smog peaks |
| PM10 | Dust, construction, pollen | Allergies, eye irritation | High construction areas |
| NO2 | Traffic, generators | Lung irritation | Busy roads |
| Ozone | Sunlight + emissions | Throat irritation | Afternoon summer peaks |
| SO2 | Coal & industries | Respiratory discomfort | Industrial towns |
Note: PM2.5 particles are extremely tiny and can enter your bloodstream,
leading to long-term health problems like asthma, bronchitis, and heart disease.
Health Impacts of Poor Air Quality
- Skin dryness, acne, dull hair
- Coughing, wheezing, asthma flare-ups
- Poor sleep quality
- Long-term heart and lung diseases
