Wildfire Smoke Isn’t Just an Outdoor Problem
Wildfire seasons are becoming longer and more intense in many parts of North America. Even if flames are miles away, microscopic smoke particles can travel long distances and enter homes through:
- Windows
- Doors
- Attic vents
- HVAC systems
- Small gaps around doors and windows
Once inside, smoke particles and odors can remain suspended in the air or settle into carpets, furniture, curtains, and bedding. Creating a clean indoor environment is one of the most effective ways to reduce exposure during smoke events.
Why Wildfire Smoke Is a Serious Indoor Air Quality Issue
Wildfire smoke contains a mixture of:
- Fine particulate matter (PM2.5)
- Gases
- Smoke odors
- Ash particles
- Other combustion byproducts
PM2.5 particles are especially concerning because they are small enough to penetrate deep into the respiratory system. Even homes with closed windows can experience smoke infiltration.
Signs Smoke Has Entered Your Home
You may notice:
- Smoky or burnt odors
- Hazy indoor air
- Increased dust or ash near windows
- Stale indoor air
- Dirty HVAC filters sooner than usual
- Eye or throat irritation during smoke events
According to Alpine Air Technologies, these are common indicators that indoor air has been affected during wildfire season.
10 Ways to Protect Your Indoor Air During Wildfire Season
1. Keep Windows and Doors Closed
During periods of unhealthy outdoor air quality, keep your home sealed as much as possible to reduce smoke infiltration.
2. Create a “Clean Air Room”
Choose one frequently used room—such as a bedroom or family room—and keep windows and doors closed while running an appropriately sized air purifier continuously.
The EPA and Alpine recommend creating a designated clean-air space during severe smoke events.
3. Run Your Air Purifier Continuously
Portable air purifiers are most effective during wildfire smoke events when operated continuously rather than intermittently. Alpine recommends ongoing operation to maintain cleaner indoor air.
4. Replace HVAC Filters
Smoke particles can load HVAC filters quickly.
Inspect filters frequently during wildfire season and replace them as recommended.
5. Set HVAC to Recirculate
If your HVAC system supports it, use the recirculation setting to reduce the amount of outdoor smoke entering your home.
6. Avoid Creating Additional Indoor Pollution
During smoke events, avoid:
- Burning candles
- Using fireplaces
- Smoking indoors
- Frying foods when possible
These activities can add more airborne particles.
7. Seal Air Leaks
Check around:
- Windows
- Doors
- Attic access points
- Utility penetrations
Reducing drafts helps limit smoke infiltration.
8. Wet-Clean Indoor Surfaces
Use damp microfiber cloths and wet mops to remove settled ash and smoke particles instead of dry dusting, which can reintroduce particles into the air.
9. Monitor Local Air Quality
Use local Air Quality Index (AQI) reports to determine when outdoor conditions improve enough for ventilation.
10. Prepare Before Fire Season
Have your air purifier cleaned and ready before wildfire season begins so it can operate at peak performance when smoke arrives.
