Sonoma County’s idyllic summers come with a fiery counterpart – wildfire season. While the risk of direct fire damage is a concern, these seasonal blazes significantly impact your home’s air quality, even miles away. Wildfire smoke is a complex mixture of gases and fine particles, including PM2.5, that can infiltrate your home through poorly sealed windows and doors. But a hidden culprit you might not consider is your air duct system. 

How Wildfire Smoke Affects Your Home’s Air Quality

Imagine your air ducts as the lungs of your house. During wildfire season, smoke carries a cocktail of harmful pollutants, including fine particulate matter (PM2.5), volatile organic compounds (VOCs), and even allergens. Here’s how wildfires can pollute your air and negatively impact your indoor air quality:

• Suction Effect: Low pressure within your home can create a suction effect, drawing smoke from outside through leaks and cracks around vents and ductwork.
• Unsealed Ducts: Many older homes have leaky ducts that allow unfiltered air, including smoke particles, to bypass your air filter and circulate freely throughout your living space.
• Contaminated HVAC System: Smoke particles can get trapped within the air ducts themselves, becoming a source of ongoing indoor air pollution long after the wildfire has subsided.

Health Effects of Wildfire Smoke Particles

The pollutants carried by wildfire smoke can have a range of negative health effects, especially for vulnerable populations like children, the elderly, and those with pre-existing respiratory problems. Here are some potential consequences of exposure to wildfire smoke particles:

• Respiratory Issues: PM2.5, a major component of wildfire smoke, can irritate the lungs and airways, leading to coughing, wheezing, shortness of breath, and difficulty breathing.
• Aggravated Allergies and Asthma: Wildfire smoke can exacerbate allergy and asthma symptoms, causing itchy eyes, runny noses, congestion, and difficulty breathing.
• Eye Irritation: Smoke particles can irritate the eyes, causing redness, watering, and discomfort.

Protecting Your Home’s Air Quality During Wildfire Season

Here are some steps you can take to minimize the impact of wildfire smoke on your indoor air quality and create a cleaner, healthier environment for your family:

• Seal Leaks: Identify and seal any leaks around windows, doors, and vent covers to prevent smoke from entering your home. Even small cracks can allow significant amounts of smoke particles to infiltrate your living space. Find out about our Air Duct Sealing Service here. 
• Upgrade Air Filters: Invest in high-efficiency particulate air (HEPA) filters for your HVAC system. HEPA filters are designed to capture a much higher percentage of smoke particles, including PM2.5, compared to standard air filters. Regularly changing your air filter, especially during wildfire season, is crucial for optimal performance.
• Schedule Air Duct Cleaning (Consider Timing): While routine cleaning is recommended every 3-5 years, consider contacting us to schedule an air duct cleaning after a major wildfire season to remove any accumulated smoke particles from your ducts. A clean air duct system ensures cleaner air circulation throughout your home. Find our more about the frequency of cleaning your air ducts and the importance of clean air in your home in our Blog. 
• Monitor Air Quality: Stay informed about current air quality conditions in your area. Several resources, including government websites and smartphone apps, provide real-time air quality index (AQI) readings. This information can help you determine when it’s necessary to take additional precautions, such as limiting outdoor activity and keeping your windows closed.
