As cooler weather moves in, San Diego homeowners spend more time indoors, often with windows closed and heaters running. That means less ventilation and more trapped dust, allergens, and stale air.
If your home feels stuffy or your allergies flare up, it’s time to take control. Here are five simple, effective ways to boost your indoor air quality this winter.
1. Replace Your Air Filters Regularly
A clean air filter keeps dust, dander, and allergens out of your air. A dirty one restricts airflow, strains your system, and spreads pollutants through your home.
Check filters monthly and replace them every 60–90 days or more often if you have pets or allergies. Clean filters mean cleaner air, lower energy use, and better performance.
2. Keep Ducts and Vents Clean
Dust, debris, and even mold can build up inside ductwork during warmer months. Once you turn on the heat, those contaminants circulate through your living space.
Schedule a professional duct cleaning to clear buildup, boost airflow, and identify leaks or insulation issues before they affect comfort and efficiency.
3. Control Indoor Humidity
Too much moisture can cause mold, too little can dry out skin and sinuses. Even in San Diego, indoor humidity shifts in winter.
Maintain humidity between 30%–50%. Use a humidifier or dehumidifier if needed, and run exhaust fans during cooking or showers to keep levels stable.
4. Use Your Ventilation Systems Wisely
When it’s cool outside, it’s tempting to keep everything sealed up, but a lack of fresh air can quickly lead to poor air circulation. Try opening windows briefly on mild days to let in fresh air.
If your HVAC system includes a fresh air intake or energy recovery ventilator (ERV), use it regularly. These systems are designed to bring in filtered outdoor air while maintaining indoor comfort and efficiency.
5. Consider Adding an Indoor Air Purifier
If your home has pets, allergies, or an older HVAC system, an air purifier can make a big difference. These systems capture fine particles, bacteria, and even airborne viruses.
Talk to your HVAC expert about options like HEPA filters or UV purifiers that integrate with your existing system for whole-home protection.
Take Charge of Your Indoor Air
Cleaner air means a healthier home. By replacing filters, cleaning ducts, balancing humidity, and upgrading ventilation, you’ll breathe easier all season long.
