Today’s guest post is from Nicholai Allen, Founder of SAFE SOSS® and Wildland Firefighter. With wildfire season getting started, it’s important to know how to keep your family safe. While a lot of folks in areas at risk for wildfires have their go bags ready and know to keep track of where evacuation notices are posted, you may be wondering how to protect your family’s lungs when wildfire smoke impacts your area. This post talks about exactly that. –Ronda
I’ve worked in smoke columns dense enough to turn noon into dusk. Even with gear on, that kind of exposure leaves you coughing for days. So when a fire is burning anywhere near my family’s home, I don’t wait to see how the air feels. I act on what the data says.
Most families go by what they can see. That’s the wrong instinct. The particles that do the real damage—fine particulate matter—are invisible. The sky can look almost clear while your kids are breathing in material small enough to pass into the bloodstream.
Here’s what I actually do, and why.
Stop Trusting the Sky and Start Checking the AQI
AirNow.gov shows real-time Air Quality Index (AQI) readings for your zip code. When AQI hits 100, you should change how your family operates outside. At 150 or above, kids stay in or evacuate, full stop. That’s not being overcautious. That’s just reading the actual conditions rather than guessing by the color of the horizon.
Your Home Isn’t As Sealed As You May Think
Closing the windows helps, but smoke still gets in: through gaps under doors, HVAC vents, attic spaces, and anywhere the building envelope isn’t tight. If you have central air, switch it to recirculate so it’s not actively pulling smoky outside air in or turn it off before you evacuate. Use MERV-13 filters or higher. The standard filters most people buy handle dust and debris, but they let wildfire smoke particles go right through.
A portable HEPA purifier in the room where your kids sleep (or you for that matter) is one of the best things you can have in place before fire season. If you don’t have one, a box fan with a MERV-13 furnace filter taped to the intake side works reasonably well—and it’s usually affordable.
One thing to skip: candles, incense, and scent “enhancers” all add irritants to the air. During a smoke event, that makes things worse.
Be Ready Early. Leave Early.
Wildfire isn’t just a wall of flame—and evacuation isn’t just about outrunning the fire front.
You’re evacuating ahead of:
- Smoke that can drop visibility to near zero
- Toxic particles that make the air unsafe to breathe
- Gridlocked roads and delayed response times
- Panicked people who waited too long
Conditions deteriorate fast—often before flames are anywhere near your home.
Waiting until you can see fire or “feel” the smoke is already too late.
When a fire is nearby, I don’t wait for urgency—I leave while it’s still controlled. That means:
- Vehicles fueled and facing out
- Essentials packed and ready
- A clear plan for where we’re going
- Acting on warnings early, not reacting late
Early evacuation is calm and deliberate. Late evacuation is chaotic and dangerous.
The goal isn’t to escape at the last minute—it’s to be gone before it becomes one.
Use Real-Time Tools, Not Just Your Eyes
I also use tools like the Watch Duty app. It gives real-time information on nearby fires, wind direction, evacuation updates, and even air quality—often faster than official alerts. You can see where a fire is moving and how conditions are changing in real time.
But the value isn’t just the alert—it’s the early signal.
If I see a fire building, wind pushing in my direction, and AQI starting to climb, I’m already making decisions. I’m not waiting for someone to tell me it’s time to go.
That’s the difference between reacting late and leaving early.
Kids May Absorb More Smoke Than Adults Do
Children breathe more air relative to their body weight, their lungs are still developing, and they’re more likely to be running around, which means deeper, faster inhalation.
Watch for persistent cough, eye irritation, unusual fatigue, or headaches. If a child with asthma isn’t responding to their normal rescue medications, call their provider. Don’t wait it out. And cloth masks won’t help here—they filter larger particles but do almost nothing against the fine material in wildfire smoke.
An N95 or KN95 respirator worn with a tight face seal is a different story: those are designed to filter fine particles, and they work when they fit correctly. For younger kids, fit is tricky; ask your pediatrician what makes sense for their age.
The Smoke Clears Before The Particles Do
After visible smoke clears, particles and ash are still settled on outdoor surfaces, clothing, and shoes. They re-enter the home every time someone comes inside. Give it at least a day after AQI readings actually drop before resuming normal outdoor activity.
Wipe down hard surfaces, change clothes after being outside, and keep kids away from any ash or disturbed soil. Once the air genuinely clears—confirm that with the AQI, not your eyes—open the windows and let the house breathe. That’s the reset, and it matters.
