Wildfire Smoke And HVAC: Protecting Indoor Air During Fire Season

When wildfire season arrives, the smoke in the air doesn’t just stay outside. It can seep indoors, making your home feel less like a safe haven and more like a smoky campground. 

So, how can you keep the air inside your home clean and breathable when the outdoors feels like a haze? The answer lies in how you manage your HVAC system.

Use Your HVAC Settings Wisely

Did you know your thermostat has a “recirculate” setting for a reason? Switching your system to recirculate prevents it from pulling smoky outdoor air inside. 

Another helpful trick is keeping your fan in the “on” position so that air keeps circulating through the filter. This simple step ensures smoke particles have less chance of settling in your home.

Upgrade Your Filters For Better Protection

Regular filters often struggle to trap fine smoke particles. That’s why experts recommend using a MERV 13 or higher filter if your HVAC system can handle it. If your unit allows, even a HEPA filter offers strong protection. 

Don’t forget portable air purifiers with HEPA filters either. Placing one in the main living areas or bedrooms adds an extra layer of defense for your lungs.

Keep The Smoke From Sneaking In

Your HVAC system can only do so much if smoke is constantly leaking into the house. Close all windows and doors tightly during fire season and look for small gaps that need sealing. 

Weatherstripping and caulking are inexpensive fixes that go a long way. Also, resist the urge to run bathroom fans, kitchen hoods, or dryers while smoke levels are high. These appliances can create negative pressure, which draws smoky air indoors.

Watch Local Air Quality Reports

Staying informed about outside air quality helps you make smart choices. Apps and local alerts can give you real-time updates so you know when to adjust your HVAC settings or add extra air purification. 

It’s also best to limit indoor pollutants at this time. Activities like burning candles or frying food only make smoky air worse.

Create A Clean Space

If the smoke outside is particularly heavy, consider setting up a temporary clean room inside your home. 

Choose a room with few windows, run a portable HEPA purifier, and keep the door closed. This can give you a safe retreat when outdoor air quality is at its worst.
