How to Use - AirWars
Step 1: Enter Two Cities
- Enter City A in the first input field (e.g., Delhi)
- Enter City B in the second input field (e.g., Beijing)
- Click "Start Battle" to compare air quality between the two cities
Step 2: See The Winner
- Winner: The city with lower AQI (better air quality)
- Cleaner Percent: See how much cleaner the winning city is
- Lower AQI = cleaner air = winner
Step 3: Review Side-by-Side Stats
- AQI: Compare Air Quality Index values (lower is better)
- Main Pollutant: See which pollutant is dominant in each city
- PM2.5: Compare fine particulate matter levels
- Cigarette Equivalence: See daily cigarette equivalent for each city
Step 4: Understand The Insight
- See how many cigarettes worth of smoke you'd save per week by moving
- This helps visualize the health impact difference between cities
- Use this for relocation decisions or travel planning
💡 Tip: This tool is perfect for comparing air quality between cities. Use it to make informed decisions about travel, relocation, or understanding pollution differences.
Frequently Asked Questions
The city with the lower AQI (Air Quality Index) wins. Lower AQI means better air quality. The tool also shows the percentage difference between the two cities, helping you understand which city has significantly cleaner air.
This shows how many cigarettes worth of smoke you'd avoid by living in the cleaner city. It's calculated by comparing PM2.5 levels and converting to daily cigarette equivalence (using the Berkeley Earth rule: 22 μg/m³ ≈ 1 cigarette), then multiplying by 7 days.
The tool fetches real-time air quality data from the AQICN API, which is updated hourly. Data timestamps are shown for each city so you know how current the comparison is.
Yes! The tool works with any cities that have air quality monitoring stations. Enter city names and the tool will fetch real-time AQI, PM2.5, PM10, and other pollutant data for comparison.
The tool shows which city has better air quality, the percentage difference, main pollutants, and health impact comparisons. It helps you understand the real-world difference in air quality between locations.
