Allergy Season Air Quality
Spring Guide for Bay Area Homeowners
The Bay Area's year-round growing season means allergies can strike any time. Spring brings the most pollen, but grass, mold, and other allergens are present throughout the year. Your HVAC system can be a powerful ally.
Upgrade to High-MERV Filters
Standard filters don't capture pollen effectively. MERV 11-13 filters trap most pollen and mold spores. MERV 16+ captures even finer particles. Replace more frequently during high-pollen periods.
Consider HEPA Filtration
Whole-house HEPA filtration or portable HEPA purifiers capture 99.97% of particles including pollen, mold, and dust mites. Place portables in bedrooms for relief while sleeping.
Control Humidity
Dust mites thrive above 50% humidity; mold grows above 60%. Keep indoor humidity between 30-50%. A dehumidifier may help in some Bay Area locations.
Keep Windows Closed
As tempting as spring weather is, open windows let pollen inside. Use AC or fans for air circulation instead. Check pollen counts before opening windows.
Regular Duct Cleaning
Ducts accumulate dust, pollen, and other allergens over time. Professional duct cleaning every 3-5 years removes this buildup. More often if you have severe allergies.
UV Germicidal Lights
UV lights installed in your HVAC system kill mold and bacteria that would otherwise grow on coils and circulate through your home.
