EPA's AirNow mobile app provides a simple interface for quickly checking current and forecast air quality information for planning daily activities and protecting your health. The app automatically displays the current AQI (Air Quality Index) for your local area or any area you wish to check, and allows you to store multiple areas for quick reference.

What’s New

Version 2.1.0

Updates to EPA’s AirNow App increase public access to information about air quality all year, including during wildfires.

The app updates add two maps to give the public additional, actionable information about air pollution at their location: the popular Fire and Smoke Map, which provides information on fire locations, smoke plumes and air quality from monitors and low-cost sensors; and the AirNow Interactive Map, which shows ozone and particulate matter from air quality monitors across the country.

The AirNow Interactive Map uses data from air monitors operated by experts to reflect particulate and ozone pollution in a given area. While particulate matter (also called “particle pollution”) is the key pollutant in smoke, ozone also can be elevated during wildfires. While the Fire and Smoke Map is the map to use during wildfire season, the Interactive Map shows ozone and particle pollution at any time of year.

Another Update

Yet another update:

This app does NOT give real-time, there are articles online that explain why. It's not a bad app, but I guess it does the job of presenting epa's official aqi?


TO ANYONE IN CALIFORNIA READING THIS, USING PURPLE AIR (browser) INSTEAD OF THIS APP. The visibility in my hometown has suddenly gotten a lot worse (in the past half hour, we have gone from 150 aqi to 500!!), but this app says we are still at 128 aqi!!) This app just does not update quickly enough!! DO NOT RELY ON THIS APP UNTIL THEY FIX IT.


The aqi on the app seems to be straight up wrong. It does accurately show the aqi listed on the official website, but I can't tell if the sensors are straight up wrong or if the data is slow-updating. For instance, last night in my area the aqi finally dropped to around 50's. Visibly the smoke had disappeared and the smell of wildfire smoke gone. Today (this morning) visibly the smoke is back and the smell is stronger than ever. This app (and its website) says that the current air quality is still only 50's aqi?! I cross-referenced with some Purple air sensors (aka community provided sensors), and the sensors near my house seem to be reporting a way-more accurate aqi of 150+. What is going on?! Can I trust this app?!


Great app that shows the aqi of any chosen city. I think it would be even better if it added the interactive map (that's already available on AirNow's website)!

How to delete a place

I really like this app and in general it is easy to use. It took me awhile, though, to figure out how to delete a location from the “places” list. To delete a location, tap “Places” at the bottom right of the home screen. The next screen will be a list of places and an option to add a new place at the bottom of the list. Tapping the settings icon at the top of the “Places” screen will give you the option to delete places from the list.

Worst AQ app ever made

Another government piece of garbage. This is the worst website and app. Do not trust and do not use. We have active wildfires going on. Ash falling from the sky. Air now says everything is fine and the airport is wonderful with a Green smiley face. Meanwhile, in the real world, it burns your eyes and throat and you can’t see to even drive, but according to the government, everything is perfectly fine! And to think, in the pandemic beginning, we trusted the government. Now we all know better!!

Anyway, stay far away from this app. It is not real time and does not show you the correct conditions. They just use this as a way to show that their stupid tree, hugging, go green agenda is doing something. If you want a real air quality reading, use IQ air or purple air. They actually give you real time data!!!
