In June 2020, the Bighorn Fire turned the Santa Catalinas into a nightly orange glow the whole city could see, and the smoke drifted down into Tucson neighborhoods for weeks. That is how wildfire smoke usually shows up here. It tends to arrive quietly, often before you catch the smell. The live map on this page tracks the fires and smoke moving near Tucson, AZ right now, today, so you can read your air before you plan your day. We've shipped filters to families through plenty of smoke seasons, and the households that stay comfortable indoors are the ones who look early and get their homes ready.
Open the map at the top of this page. It pulls active fires, smoke plumes, and Tucson's current AQI into one view and refreshes throughout the day. Here's how we read it fast:
Active fires: red markers flag forest fire activity near Tucson and across Pima County.
Smoke plumes: the smoke layer shows where haze is drifting over the metro right now.
Local AQI: The color band tells you whether today's air is safe for time outside.
Your move: once the AQI passes 150, stay in, keep the windows shut, and run your HVAC with a MERV 13 filter.
Tucson sits right against the Coronado National Forest, so smoke from a forest fire can reach the metro in a few hours.
The live map puts active fires, smoke spread, and your current AQI in one place, updated throughout the day.
Once the AQI passes 150, the air is unhealthy for everyone, not only sensitive groups.
Fine smoke particles work their way indoors through windows, doors, and your HVAC system.
A MERV 13 pleated filter is the simplest thing standing between outdoor smoke and the air your family breathes.
Our live fire map for Tucson, AZ, gathers active incident data in one spot, so you're not bouncing between five tabs during a bad-air morning. Red markers point to active fires. Shaded outlines show how far each one has spread. Most of the fires that gray out Tucson's sky start on the forest land around us, where dry brush and triple-digit heat can turn one spark into a fast run. If you want the background on how wildfires start and spread, the basics of ignition and wind-driven growth explain how a fire can still smudge your sky.
Check the marker closest to Tucson first, then zoom out across Pima County.
Watch each fire's outline grow, since a spreading fire usually means more smoke headed your way.
Read the wind direction in the forecast, because that decides whether the smoke reaches your street.
Fire is only half the story. The smoke layer shows where particles are drifting across the metro, and the AQI number tells you what that means for your lungs. Thin haze fools people. It can still carry enough fine particles to set off a cough or tighten a chest, and that's the whole reason we pair the map with a live reading you can act on. This is the part of the air you can't see, made plain.
0 to 50, green: clean air, good for everyone.
51 to 100, yellow: acceptable, though unusually sensitive folks should notice how they feel.
101 to 150, orange: unhealthy for sensitive groups like kids, older adults, and anyone with asthma.
151 and up, red or worse: unhealthy for everyone, so cut your time outside and keep the indoor air clean.
When smoke settles over Tucson, the cleanest air around is inside your own home, as long as you keep it sealed and filtered. Shut the windows and doors. Set your HVAC fan to the on setting so it keeps cycling air through the filter. Then let a MERV 13 filter catch the fine particles the EPA flags as the real hazard in smoke. Smoke also has a long tail. It doesn't clear the second a fire is contained, so if you're wondering how long wildfire smoke stays in the air, plan to keep filtering well after the flames are out.
Seal up: close windows, doors, and the obvious gaps around your house.
Run the fan: Use the on setting so the air keeps moving through the filter instead of sitting still.
Move up to MERV 13: it's the lowest household rating that reliably traps wildfire PM2.5.
Swap it early: heavy smoke can load a filter in weeks instead of months, so check it often.
When wildfire smoke reaches Tucson, the particles that do the most harm are the ones nobody can see. After manufacturing filters for over a decade and serving more than two million households, we've watched a good MERV 13 filter change what a family actually breathes during a smoke event, sometimes within an hour of switching it in.

Three numbers explain why we treat Tucson smoke days the way we do.
Researchers studying Southern California found that a 10 microgram per cubic meter rise in wildfire-specific PM2.5 lined up with a 1.3 percent to 10 percent jump in respiratory hospitalizations, against 0.67 percent to 1.3 percent for the same dose of ordinary PM2.5. That gap matches what we hear from customers. The symptoms show up fast.

State health data puts adult asthma prevalence near 9.8 percent, close to the national rate. For those neighbors, a smoky afternoon isn't a small thing. It's a trigger.

Here's our honest read after a lot of fire seasons. Checking the map is a good habit, but it tends to put people in react mode, refreshing the screen and hunting for a filter that just sold out. The families who handle smoke calmly flipped that around. They treat the map like a quick weather check, and they made the one change that improves their indoor air long before they needed it.
Treat the map as a morning glance during fire season, not a one-time check.
Trust the AQI number over how the sky looks, because thin haze still carries the particles that matter.
Keep a spare MERV 13 on the shelf, the way you keep batteries for a flashlight.
Clean indoor air during a wildfire isn't luck. It's a short list of choices you control, and you're the one who keeps your home safe.
Check the map first. Look at today's Tucson AQI before any outdoor plans. Over 150, stay in.
Seal the house. Close windows and doors. Set the HVAC fan to on so it keeps cycling indoor air.
Know your rating. Below MERV 13 is the upgrade to make. It's the lowest rating that reliably traps wildfire PM2.5.
Stock a spare. Find your filter size and keep a MERV 13 on the shelf, ready before the next plume.
Set up a clean room. Pick the room with the fewest windows for kids, older adults, and anyone with asthma.
Make it routine. Bookmark this page and check the AQI each morning through fire season.
Start with the live map at the top of this page. It shows active fire markers and perimeters near Tucson and refreshes throughout the day. For incident-level detail, cross-check the federal sources listed above.
Use the smoke layer on the map above to see plume coverage over the metro, then confirm your own neighborhood with the local AQI value shown next to it.
Fire activity shifts hour to hour. The map flags current forest fire incidents in the Coronado National Forest and nearby areas, so treat any close one as a reason to watch your indoor air.
Above 100, the air is unhealthy for sensitive groups. Above 150, it's unhealthy for everyone. During heavy smoke, Tucson readings can pass both marks in a few hours.
It slips in through open windows, doors, and small gaps, and it rides in through your HVAC system. Running that system with a MERV 13 filter catches a lot of the fine particles that drift inside.
A MERV 13 pleated filter does the most during a smoke event, because it's the lowest household rating that reliably traps PM2.5. We build them in the sizes most Tucson homes use, including the hard-to-find ones.
When the next fire pushes smoke across Tucson, the filter in your HVAC is what stands between that smoke and the air your family breathes. Find your size at Filterbuy and keep a MERV 13 on hand before the haze rolls in.
