Indoor Air Quality Tips for Bay Area Allergy Sufferers
Reduce allergens in your home with these HVAC and air quality strategies. Filter upgrades, purifiers, and humidity control for allergy relief.
The Bay Area grass pollen season, tree pollen season, and wildfire smoke season create a triple challenge for allergy sufferers. Here is how to make your home a refuge from outdoor allergens.
Upgrade Your HVAC Filter
The single most effective change is upgrading from a basic MERV 4 filter to MERV 11 or higher. MERV 11 captures pollen, mold spores, dust mite debris, and pet dander. MERV 13 adds fine particle capture that helps during wildfire smoke events. Check that your HVAC system can handle the higher-rated filter without airflow restriction.
Run the Fan Continuously
Setting your thermostat fan to ON instead of AUTO circulates air through the filter continuously, not just when the system is heating or cooling. This provides ongoing air filtration throughout the day.
Add Air Purification
For severe allergies, a whole-home air purifier integrated into your HVAC system provides an additional level of filtration. HEPA filtration captures 99.97% of particles. UV-C germicidal lights destroy mold spores and bacteria. These systems treat all air flowing through your HVAC.
Control Humidity
Dust mites and mold thrive in humidity above 50%. Use a hygrometer to check your indoor humidity levels. If they are consistently above 50%, a whole-home dehumidifier integrated with your HVAC system can reduce humidity to the 35-45% range where allergens are less active.
Clean Ducts Periodically
Even with good filtration, dust, pollen, and pet dander accumulate in ductwork over time. Professional duct cleaning every 3-5 years removes this buildup and reduces the allergen load in your home.
Keep It Sealed
During high pollen days, keep windows and doors closed and rely on your HVAC system for ventilation and filtration. An Energy Recovery Ventilator can bring in fresh outdoor air through a HEPA filter, providing ventilation without opening windows.
