Indoor Air Quality Cheat Sheet During Severe Weather

Severe weather events, such as hurricanes, floods, wildfires, and extreme heat, can significantly affect indoor air quality (IAQ). Understanding these impacts and implementing preventive measures are crucial for maintaining a healthy indoor environment.

How Does Severe Weather Affect Indoor Air Quality?

• Flooding: Floodwaters can introduce contaminants into homes, leading to mold growth and increased levels of bacteria and viruses. These pollutants can degrade indoor air quality and pose health risks. (epa.gov)

• Wildfires: Smoke from wildfires can infiltrate buildings, raising levels of particulate matter (PM2.5) indoors. Exposure to these particles can irritate the respiratory system and exacerbate existing health conditions. (epa.gov)

• Extreme Heat: High temperatures can lead to the use of air conditioning systems, which may circulate indoor pollutants if not properly maintained. Additionally, heat can cause the release of volatile organic compounds (VOCs) from building materials and furnishings. (epa.gov)

Strategies to Maintain Indoor Air Quality During Severe Weather

1. Monitor Indoor Air Quality: Use air quality sensors to keep track of pollutant levels inside your home. These devices can help you take timely action when air quality deteriorates. (epa.gov)

2. Seal Entry Points: Keep windows and doors closed during severe weather to prevent outdoor pollutants from entering. Ensure that seals and weatherstripping are intact to minimize infiltration. (epa.gov)

3. Use Air Purifiers: Deploy portable air cleaners equipped with high-efficiency particulate air (HEPA) filters to reduce indoor pollutant levels. These devices can effectively capture airborne particles, including smoke and dust. (epa.gov)

4. Maintain HVAC Systems: Regularly replace filters in heating, ventilation, and air conditioning (HVAC) systems to ensure efficient operation. During wildfire smoke events, set your HVAC system to recirculate mode to prevent outdoor air from entering. (epa.gov)

5. Control Humidity: Keep indoor humidity levels between 30% and 50% to prevent mold growth. Use dehumidifiers in damp areas and ensure proper ventilation in bathrooms and kitchens. (lrapa-or.gov)

6. Avoid Indoor Pollutant Sources: During severe weather, refrain from activities that can introduce pollutants indoors, such as smoking, burning candles, or using gas stoves. These actions can exacerbate indoor air quality issues. (epa.gov)
