🌎 Why Check Air Quality by ZIP Code?

Air quality can vary dramatically within the same city. Industrial zones, busy highways, and dense urban cores often have PM2.5 levels 3 to 5 times higher than suburban or park areas just a few miles away. Checking by your exact ZIP code gives you the most relevant reading for where you actually live, work, or plan to exercise.

This tool pulls real-time data from the nearest verified WAQI monitoring station to your postal code, covering 180+ countries with over 30,000 stations worldwide.

❓ Frequently Asked Questions

Does this work outside the United States?

Yes. Select your country from the dropdown. We support postal codes from 18+ countries including the UK (postcodes), India (PIN codes), Canada, Australia, Germany, Japan, and more. Coverage depends on monitoring station density in your area.

How accurate is the data for my specific location?

We find the nearest official monitoring station to your postal code. In dense cities the station may be within 1 to 2 km. In rural areas it may be 15 to 30 km away. The AQI shown reflects that station’s readings, which are the best available estimate for your area.

How often does the data update?

WAQI monitoring stations update hourly. Some high-traffic urban stations update every 15 to 30 minutes. The data shown is always the most recent reading available from that station.

What is a safe AQI reading?

The US EPA standard: 0 to 50 is Good, 51 to 100 is Moderate, 101 to 150 is Unhealthy for Sensitive Groups, 151 to 200 is Unhealthy, 201 to 300 is Very Unhealthy, and above 300 is Hazardous. Outdoor activity should be avoided at Hazardous levels.

What does cigarettes per day mean?

Berkeley Earth researchers found that breathing air with PM2.5 of 22 micrograms per cubic metre for 24 hours delivers a comparable particulate dose to smoking one cigarette. Dividing the current PM2.5 reading by 22 gives an intuitive sense of pollution exposure.
