Alaska’s dry winter has set the stage for an early and potentially severe wildfire season. With record-low snowpack and drier-than-usual conditions, the risk of wildfires is higher, and with it comes the threat of smoke infiltrating homes. Poor indoor air quality from wildfire smoke can lead to respiratory issues, allergies, and long-term health effects. The good news? Your HVAC system can be your first line of defense in keeping your home’s air clean and safe. Here’s how to prepare your home for wildfire season and ensure your indoor air remains fresh and breathable.
How Wildfire Smoke Affects Indoor Air Quality
Wildfire smoke contains fine particulate matter (PM2.5), carbon monoxide, and other harmful pollutants that can easily enter homes through windows, doors, and ventilation systems. These particles are small enough to penetrate deep into the lungs, leading to respiratory issues, irritation, and worsened conditions for those with asthma or allergies. Even if a fire isn’t directly near your home, smoke can travel long distances, making air quality concerns widespread.
Steps to Protect Your Indoor Air During Wildfire Season
1. Upgrade Your HVAC Filters
Not all air filters are created equal, and during wildfire season, high-efficiency filters are essential. Look for filters with a Minimum Efficiency Reporting Value (MERV) rating of 13 or higher. These filters capture fine particles, including smoke, dust, and allergens, keeping your indoor air cleaner. Be sure to check and replace filters regularly—especially during high-smoke periods.
2. Keep Windows and Doors Sealed
When air quality outside is poor, your best defense is keeping smoke out. Ensure that all windows and doors are properly sealed, and use weather stripping to close any gaps. If possible, keep windows closed and rely on your HVAC system for ventilation rather than opening up your home to outside air.
3. Run Your HVAC System on Circulate Mode
Setting your HVAC fan to “on” instead of “auto” helps continuously filter the air in your home. This keeps smoke particles from settling and allows your system to capture more airborne pollutants throughout the day.
4. Consider an Air Purifier
A standalone air purifier with a HEPA filter can provide an additional layer of protection, especially in bedrooms and living areas. Look for air purifiers that are specifically designed to remove smoke and airborne contaminants.
5. Ensure Proper Ventilation Without Bringing in Smoke
Some HVAC systems have a fresh air intake that could pull in smoky air from outside. If your system has this feature, temporarily closing the intake during heavy smoke conditions can prevent contamination. At the same time, make sure exhaust fans in bathrooms and kitchens are used minimally, as they can draw in outside air.
6. Schedule an HVAC Inspection and Tune-Up
A well-maintained HVAC system functions more efficiently and can better filter out harmful particles. Having a professional inspect and service your system before wildfire season ensures that it’s working at peak performance. This includes checking air ducts, cleaning coils, and confirming that your filter system is optimized for high-smoke conditions.
7. Keep Outdoor Vents and Areas Clean
Debris and dry vegetation near your home can increase fire risks and clog outdoor vents, reducing your HVAC’s efficiency. Regularly clear away leaves, brush, and any flammable materials around your property to improve both safety and air quality.
8. Monitor Indoor Air Quality Levels
Investing in an indoor air quality monitor can help you stay informed about the conditions inside your home. These monitors detect levels of particulate matter and other pollutants, allowing you to adjust your air filtration and purification strategies as needed.
Stay Ahead of Wildfire Season with Proactive HVAC Maintenance
With Alaska facing an early wildfire season, now is the time to take steps to protect your home’s indoor air quality. By upgrading your HVAC filters, sealing your home, and using air purification strategies, you can create a healthier environment for you and your family.
