Understanding Air Quality

A comprehensive guide to interpreting AQI levels and protecting your long-term health.

Air Quality Awareness

How to Read AQI Levels

AQI values are grouped into specific ranges. Each range corresponds to a level of health risk. Understanding these numbers is the first step in prevention.

0–50
Good

Air quality is satisfactory, and air pollution poses little or no risk.

51–100
Moderate

Air quality is acceptable. However, there may be a risk for some people who are unusually sensitive to air pollution.

101–150
Unhealthy for Sensitive Groups

Members of sensitive groups may experience health effects. The general public is less likely to be affected.

151–200
Unhealthy

Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.

201–300
Very Unhealthy

Health alert: The risk of health effects is increased for everyone.

301+
Hazardous

Health warning of emergency conditions: everyone is more likely to be affected.

Why AQI Ranges Matter

  • Decide whether it is safe to exercise outside.
  • Protect vulnerable family members (children, elderly).
  • Plan travel and daily commutes safely.
  • Reduce long-term cardiovascular risks.

Health Effects

Breathing polluted air affects both short-term performance and long-term longevity. Even healthy individuals can experience symptoms during high pollution spikes.

Health Effects Infographic

Short-Term Effects

  • Irritation of eyes, nose, and throat
  • Coughing and chest tightness
  • Shortness of breath
  • Fatigue and headaches

Long-Term Risks

  • Chronic respiratory disease (COPD, Asthma)
  • Reduced lung function
  • Cardiovascular disease and stroke
  • Impact on reproductive health

Vulnerable Groups

Certain individuals are more susceptible to the adverse effects of air pollution and require stricter precautions.

Children

Children

Developing lungs and higher breathing rates make them highly susceptible.

Elderly

Elderly

Often have weaker immune systems or pre-existing conditions.

Respiratory Issues

Respiratory Issues

People with asthma or COPD can suffer immediate attacks.

Pregnant Women

Pregnant Women

Pollution can impact fetal development and maternal health.

Protection Strategy

If you belong to these groups, use air purifiers indoors and wear N95 masks if you must go outside during poor AQI days.
