Chandler's air is good more often than not, but the East Valley carries two federal nonattainment pollutants at once: windblown dust (PM10) and summer ground-level ozone. Most years the air turns genuinely bad in two predictable windows — a haboob rolling through during monsoon season, roughly June through September, or a run of 110-degree afternoons that cooks vehicle exhaust into ozone smog.
Canairy watches the sensors around your home, your kids' school, and everywhere else you care about, and tells you in plain English when the air changes enough to matter.
Chandler carries two federal nonattainment pollutants
Since 1990, the Phoenix-area PM10 nonattainment area — which covers Chandler and the rest of Maricopa County — has carried a formal "moderate" nonattainment designation under the Clean Air Act for windblown dust. Chandler's own Environmental Management office describes PM-10 as particles "about the size of flour grains" that build up in the morning air and are hardest on kids and older adults.
Ozone is the other half of the story. From May 1 through September 30, Arizona runs the Governor's Ozone Alert Program, and ADEQ announces an alert before noon on the day before pollution is expected to spike, broadcast on local radio. The chemistry is straightforward: tailpipe exhaust and other emissions react with intense desert sun and heat, and Chandler's summer — with highs regularly past 110°F — supplies plenty of both.
The 2011 haboob that put the Valley's dust on the map
On July 5, 2011, a wall of dust nearly 100 miles wide and more than 5,000 feet tall rolled across the Phoenix metro from Carefree down to the Estrella Mountains, turning daylight to darkness over Chandler, Gilbert, Mesa, Avondale and Goodyear. It's still the largest haboob on record here, but it wasn't a one-off — Arizona's monsoon season produces blowing-dust and dust-storm warnings from the National Weather Service most years.
Because dust events form suddenly and move fast, Maricopa County runs a Rapid Response Notification System that alerts subscribers by neighborhood when pollution starts climbing and where the hot spot is. Canairy works the same problem differently: instead of one county-wide reading, it pulls from the dense PurpleAir network across the East Valley, so the number you see reflects sensors near your own house, not a monitor miles away.
Winter has its own rule: No Burn Days
Dust and ozone are warm-season problems; winter brings a quieter one. On cold, still nights the Salt River Valley's temperature inversions trap smoke close to the ground, so Maricopa County declares "No Burn Days" that bar wood-burning fireplaces, chimineas and outdoor fire pits — gas and electric devices are still allowed. The county's "Burn Cleaner, Burn Better" program will put up to $2,000 toward converting an old wood fireplace to gas.
Chandler's own year-round checklist for residents — the city calls it "the Dirty Dozen" — includes cutting car trips on advisory days, skipping gas-powered leaf blowers, not burning yard waste, and keeping bare dirt covered so it doesn't turn into next summer's dust. None of it cancels out a haboob or a 115-degree ozone day, but it's the difference between a bad air day and a worse one.
Chandler air quality FAQ
What is the air quality in Chandler right now?
This page shows the current AQI for Chandler, calculated from PurpleAir sensors across the city and updated continuously. The map below shows every live sensor, so you can check the reading closest to your own neighborhood.
Why does Chandler get dust storms in the summer?
Chandler sits in the East Valley of the Sonoran Desert, where monsoon thunderstorms between June and September can trigger haboobs — dense walls of blowing dust pushed ahead of a storm's downdraft. The largest on record hit on July 5, 2011, a wall of dust nearly 100 miles wide that darkened the sky over Chandler, Gilbert and Mesa. Maricopa County's PM10 nonattainment status reflects how often windblown dust pushes particle pollution past the federal health standard here.
Why do I hear about "No Burn Days" in Chandler winters?
On cold, still nights the Salt River Valley traps smoke close to the ground, so Maricopa County calls "No Burn Days" that bar wood-burning fireplaces, chimineas, and fire pits countywide, including in Chandler — gas and electric fireplaces are still fine. The county's Burn Cleaner, Burn Better program will even put up to $2,000 toward switching an old wood fireplace to gas.
What AQI level is unhealthy?
Under the US EPA scale, AQI 0-50 is Good and 51-100 is Moderate. From 101 the air is Unhealthy for Sensitive Groups - kids, older adults, and people with asthma or heart conditions - and above 150 it's Unhealthy for everyone. Canairy translates these numbers into a plain-English verdict, like whether to close the windows or move a workout indoors.
Where does Canairy's Chandler data come from?
Readings come from PurpleAir's network of laser particle sensors across Chandler and surrounding towns, cross-referenced with government monitors and the Google Air Quality API. You can see every sensor behind your numbers on the live map - there's no black box.
