Wildfires may seem like a problem limited to the western United States, but their effects often travel hundreds or even thousands of miles. In recent years, smoke from Canadian and western U.S. wildfires has significantly impacted air quality throughout the Chicagoland area. Even when fires are far away, fine smoke particles can create unhealthy outdoor conditions and find their way indoors.
Because most people spend the majority of their time inside their homes, maintaining good indoor air quality becomes especially important during wildfire season. Understanding how smoke affects your home can help you take steps to keep your indoor environment cleaner and healthier. Let’s take a closer look.
Wildfire Smoke Can Enter Your Home
Many homeowners assume their home naturally protects them from outdoor pollution. While walls and windows provide some protection, smoke particles are incredibly small. Fine particulate matter, known as PM2.5, can enter through tiny gaps around doors and windows, attic spaces, ventilation systems, and even small air leaks throughout the home’s structure.
Once inside, these particles can remain suspended in the air for hours, circulating through your HVAC system and affecting the air your family breathes.
Why Indoor Air Quality Matters
Poor indoor air quality can affect anyone, but certain individuals are especially vulnerable. Children, older adults, people with asthma, allergies, COPD, or heart conditions may experience increased symptoms when exposed to wildfire smoke.
Even healthy adults may notice irritation such as:
- Scratchy throat
- Burning eyes
- Headaches
- Coughing
- Fatigue
- Difficulty breathing during physical activity
Reducing smoke exposure indoors helps minimize these risks during periods of poor outdoor air quality.
Your HVAC System Plays an Important Role
Your home’s heating and cooling system can help improve indoor air quality, but only if it is operating properly.
A clean, properly sized air filter captures airborne particles before they continue circulating throughout the home. During wildfire events, homeowners should check filters more frequently since they may become clogged faster than usual.
Running your HVAC fan can also help continuously move indoor air through the filtration system, allowing more smoke particles to be captured over time.
Air Leaks Can Reduce Indoor Protection
Even the best HVAC equipment has limitations if outdoor air is constantly leaking into the home.
Air leaks around windows, doors, attic penetrations, recessed lighting, and ductwork allow smoke to enter while allowing conditioned indoor air to escape. These leaks not only reduce energy efficiency but also make it harder to maintain healthy indoor air during smoke events.
Professional blower door testing can identify areas where outside air is infiltrating the home so improvements can be made to strengthen the building envelope.
Ductwork Can Affect Air Quality Too
Leaky ductwork may draw polluted air from attics, crawl spaces, or other unconditioned areas into your HVAC system. If wildfire smoke has entered these spaces, the duct system can distribute those particles throughout the home.
Professional duct testing can identify leakage problems that reduce HVAC efficiency and compromise indoor air quality.
Stay Informed During Smoke Events
The Air Quality Index (AQI) provides valuable information about outdoor conditions. When AQI levels become unhealthy, it is wise to keep windows and doors closed, avoid unnecessary outdoor ventilation, and minimize activities that introduce outdoor air into the home.
Taking proactive steps before wildfire smoke arrives can make a significant difference in maintaining healthier indoor air.
Professional Testing Helps Identify Hidden Problems
Many indoor air quality issues are difficult to detect without specialized equipment. Professional evaluations, including blower door testing, duct testing, and HVAC performance assessments, provide valuable insight into how outdoor pollutants may be entering your home. Addressing these hidden issues not only improves comfort and energy efficiency but also helps create a cleaner indoor environment during wildfire season and throughout the rest of the year.
