Real-Time Air Quality Tracking & Family Safety Alerts
By the time you can smell wildfire smoke inside your house, indoor PM2.5 has typically been climbing for two to three hours. That gap is what this page exists to close. The map on this page pulls live readings from EPA and U.S. Forest Service air monitors across Oklahoma County, layered with satellite fire detections from NOAA's Hazard Mapping System, so you see what's heading toward Oklahoma City before your nose does.
We've spent more than a decade manufacturing filters and watching what wildfire smoke does to indoor air in over two million households. Oklahoma sits in a position no other state quite matches. Spring grass fires light up Cleveland, Canadian, and Logan counties almost weekly during red flag warnings. Summer winds drag smoke up from Texas and across Kansas. By late season, Canadian plumes settle into the metro for days at a time. The map below tells you which of those threats is active right now. The rest of this page tells you what to do about it.

The live map on this page pulls real-time data from the AirNow Fire and Smoke Map, built jointly by the EPA and the U.S. Forest Service. It displays active fire perimeters, satellite-detected hotspots, NOAA smoke plume coverage, and PM2.5 readings from monitors across Oklahoma County and the surrounding metro.
Check the AQI reading on the live map above for current conditions at sensors closest to your zip code. Green and Yellow categories (0 to 100) are safe for most outdoor activities. Orange (101 to 150) calls for precautions among sensitive groups. Red (151 and above) means everyone should cut outdoor exposure and run HVAC on continuous fan with a MERV 13 filter.
The map shows two layers of fire data: large fire incidents from the National Interagency Fire Center and satellite-detected hotspots from NOAA's Hazard Mapping System. Click any fire icon to see latitude, longitude, and incident details. Oklahoma's highest local risk runs from March through May during grass fire season. Long-range smoke from Texas, Kansas, and Western fires can reach the metro any month of the year.
Close windows and doors. Switch your HVAC fan to "On" for continuous filtered circulation. Upgrade to a MERV 13 filter. Set up a clean room with a portable HEPA cleaner. Skip indoor activities that generate particles, such as frying, using candles, and vacuuming. Sensitive groups should stay indoors when AQI reaches 101 or higher.

Oklahoma City air quality can be degraded by fires hundreds or thousands of miles away, including in Texas, Kansas, the Western U.S., and Canada.
MERV 13 is the EPA-recommended minimum filter rating for capturing wildfire smoke particles in most home HVAC systems.
Switching your thermostat fan from "Auto" to "On" during a smoke event can reduce indoor particle concentrations by up to 24 percent, per the EPA.
Children, older adults, pregnant women, and anyone with asthma, COPD, or heart disease should take extra precautions when AQI reaches 101 or higher.
Spring (March through May) brings peak local grass fire risk in Oklahoma. Summer and early fall bring long-range smoke drift from Western and Canadian fires.
If commercial air cleaners are unavailable, an EPA-tested DIY box-fan unit with a MERV 13 filter raises clean air delivery by 123 percent.
AirNow runs the data feed powering the map above. EPA and the U.S. Forest Service built it to combine ground-level PM2.5 readings from monitors across Oklahoma with satellite fire hotspots and smoke plume polygons from NOAA's Hazard Mapping System. Click any sensor icon near Oklahoma City to open a dashboard with the current NowCast AQI, recent trend, and any active Smoke Forecast Outlook the Air Resource Advisors have issued for the area.
The Air Quality Index turns raw PM2.5 numbers into a color and a recommendation. Match today's reading on the map widget against the categories below before any outdoor activity:
Good (0–50, Green): Air quality poses little or no risk.
Moderate (51–100, Yellow): Unusually sensitive people should consider easing back on prolonged outdoor exertion.
Unhealthy for Sensitive Groups (101–150, Orange): Children, older adults, and people with heart or lung disease should reduce outdoor activity.
Unhealthy (151–200, Red): Everyone may begin to feel health effects. Sensitive groups should stay indoors.
Very Unhealthy (201–300, Purple): Health alert. Significant risk for the entire population.
Hazardous (301+, Maroon): Emergency conditions. Everyone is more likely to be affected.
Smoke reaches the OKC metro from several directions, and the local geography is what makes Oklahoma City an unusually exposed spot for wildfire impact. The Cross Timbers grasslands ignite fast in dry, windy conditions. The Red River basin south of the city is Texas's exit ramp for grass fire smoke heading north. Prevailing southerly winds from May through September carry plumes from regional fires straight into Oklahoma County and the surrounding metro.
Fires don't have to burn nearby to affect your indoor air. Smoke from Western U.S. and Canadian boreal fires regularly travels two thousand miles or more, settling into the Southern Plains as a haze that pushes Oklahoma City's AQI above 100 even when no local fire shows on the map. The view above includes both layers: nearby fire perimeters and long-distance plume coverage.
NOAA's HRRR-Smoke model and the National Weather Service office in Norman produce 24- to 48-hour smoke forecasts specific to Oklahoma. Spring is when local fire risk peaks, with red flag warnings hitting western counties almost weekly during March, April, and May. By summer and early fall, the threat shifts to long-range transport: fires across the Mountain West and Pacific Northwest can degrade Oklahoma City air for days at a stretch without a single local fire on the map.
Once the AQI climbs into Orange or higher, your job shifts from watching the map to keeping smoke out of your house. Run through these in order:
Close every window, door, and HVAC fresh-air intake or economizer setting.
Switch your thermostat fan from "Auto" to "On" so filtered air keeps moving.
Upgrade to a MERV 13 filter once AQI reaches 101 or higher. That's EPA's recommended minimum for wildfire smoke.
Set up one room as a clean room and run a portable HEPA cleaner sized for that room's square footage.
Skip indoor activities that load the air with more particles: frying, candles, vacuuming, and wood stoves.
Check the filter every two weeks during a sustained smoke event. Heavy smoke can clog a MERV 13 in 30 to 60 days.
"After more than a decade of testing how filters perform during smoke events, we've found that Oklahoma homeowners who upgrade to MERV 13 before the AQI crosses 150, not after, see the biggest cut in indoor PM2.5. The mistake we see most often is waiting until the smoke is visible. By the time you can smell it, fine particles have already settled across your living room and your kid's bedroom. Watch the map for the warning, and use the filter as the response."

Annual report grading air quality across U.S. metros, including Oklahoma City. The report tracks long-term particle pollution and ozone trends, so you can put any single smoke event in context against the metro's baseline air quality.
Numbers tell the story; smoke alone can't. The three statistics below come from peer-reviewed research and EPA testing, each pulled from a unique .gov source. They're the data points we keep coming back to when explaining why proactive filtration beats emergency response — and why upgrading from a MERV 8 to a MERV 13 isn't a small adjustment, it's the difference between protecting your home and reacting after the smoke is already inside.
Peer-reviewed research analyzing data from 2007 through 2018 found that wildfire smoke contributed more than 25 percent of daily PM2.5 concentrations at roughly 40 percent of all regulatory monitors in EPA's Air Quality System for more than one month per year. The pattern held well outside the traditional Western fire zones, including across the Southern Plains.

EPA research found that adding a single 4-inch MERV 13 filter to a basic box-fan air cleaner raises the Clean Air Delivery Rate by 123 percent. For a smaller room during a smoke event, particularly when commercial purifiers sell out, that's a serious protective option built from parts you can find at any hardware store.

Wildfire smoke stopped being a Western states problem years ago. Oklahoma City now catches plumes from local grass fires, regional drift out of Texas and Kansas, and long-range smoke that travels from the Pacific Northwest, the Mountain West, and Canada. After watching that pattern build through the past decade, our position is straightforward: homeowners who do best during smoke events treat filtration as an everyday HVAC system, not an emergency purchase.
Bookmark this map. Check it the same way you check a weather radar during severe storm season. When the AQI crosses 100, your HVAC filter becomes the single most important air quality tool in your house. A MERV 8 will let you taste the haze indoors. Run a MERV 13, and your family won't notice the smoke is outside until they look out the window.
Bookmark this page so you can pull up the live Oklahoma City wildfire and smoke map within seconds during the next event.
Check the current AQI reading on the map above and match it against the category guidance to set today's outdoor activity level.
Pull the filter from your HVAC return and check its MERV rating. Most homes ship from the builder with a MERV 4 to MERV 8 filter, which lets the majority of wildfire smoke particles through.
Order MERV 13 replacement filters in your sizes now, before the next red flag warning, so you have them on hand when smoke arrives.
Set a calendar reminder to check your filter every two weeks during fire season. Heavy smoke shortens replacement intervals fast.
The AirNow Fire and Smoke Map data feeds powering the map above update throughout the day. PM2.5 monitor readings refresh hourly using the NowCast AQI calculation. Satellite fire detections refresh as each new orbital pass completes. NOAA's Hazard Mapping System smoke plume polygons update several times per day. Refresh this page to pull the latest data.
Healthy adults typically start to feel effects when the AQI reaches 151 or higher (Unhealthy, Red category). EPA recommends easing back on prolonged or heavy outdoor exertion at that level. Sensitive groups should take action earlier, starting at AQI 101 (Unhealthy for Sensitive Groups, Orange). That includes children, older adults, pregnant women, and anyone with asthma, COPD, heart disease, or diabetes.
Yes, regularly. Oklahoma City sits directly in the path of wind flows that move smoke between the Southern Plains states. Texas grass fires south of the Red River push smoke into the OKC metro under southerly winds in spring. Kansas Flint Hills prescribed burns in April can degrade Oklahoma County air quality for several days when winds turn northerly.
Yes, with two adjustments. Close any fresh-air intake or economizer setting so your system recirculates indoor air instead of pulling smoke in from outside. Switch the thermostat fan from "Auto" to "On" to keep filtered air circulating. EPA testing shows continuous fan operation reduces indoor particle concentrations by up to 24 percent compared with running the fan on "Auto."
MERV 13 is EPA's recommended minimum for capturing wildfire smoke particles in most residential HVAC systems. Higher ratings (MERV 14 to MERV 16) capture more, but you'll want to confirm your system can handle the additional pressure drop before upgrading that far. After more than a decade of manufacturing filters, our guidance is straightforward: upgrade to MERV 13 before fire season starts, then check the filter every two weeks once smoke arrives.
Local grass fire smoke usually clears within 24 to 48 hours once the fire is contained and the winds shift. Long-range smoke from Western U.S. or Canadian fires can hang over Oklahoma City for three to seven days, and during major fire seasons, the region has seen multi-week stretches of elevated PM2.5. The live map above shows current plume coverage. NOAA's HRRR-Smoke forecast extends 24 to 48 hours out.
You've checked the map, and you know what's coming. The next step is making sure your HVAC system is ready to stop wildfire smoke at the filter before it reaches your kids' bedrooms.
