Why Indoor Air Quality Matters in Winter

When winter arrives in San Jose and across the Bay Area, most families keep their homes sealed tight to stay warm and reduce heating costs. While this helps with energy efficiency, it also traps dust, allergens, and pollutants indoors. Without proper ventilation and filtration, your home’s indoor air quality (IAQ) can decline—impacting not just comfort, but also your family’s health.

The Hidden Risks of Poor Indoor Air Quality

• Allergens & Dust – Dust mites, pet dander, and pollen can recirculate through your HVAC system, causing allergies to flare up.

• Dry Air Problems – Low humidity during winter leads to dry skin, static electricity, irritated sinuses, and even increased spread of colds and flu.

• Pollutant Buildup – Everyday activities like cooking, cleaning, or using certain household products release particles and volatile organic compounds (VOCs).

• Mold & Mildew – Excess moisture from poor ventilation can encourage mold growth inside ductwork, basements, or bathrooms.

• Long-Term Health Effects – Prolonged exposure to indoor pollutants can worsen asthma, allergies, and respiratory issues.

Proven Ways to Improve Indoor Air Quality in Winter

✅ Install a Whole-Home Air Purifier
Unlike portable units, whole-home purifiers are integrated directly into your HVAC system. They capture dust, pollen, pet dander, smoke, and even microscopic particles, ensuring every room gets cleaner, healthier air.

✅ Use a Humidifier for Balanced Air
Winter air in the Bay Area often feels dry, especially when heaters run daily. A whole-home humidifier restores healthy moisture levels, protecting wood furniture, preventing dry skin, and reducing static electricity.

✅ Schedule Professional Duct Cleaning
Dust, pet hair, and debris collect inside ductwork over time. When your furnace kicks on, those contaminants circulate through your home. A professional duct cleaning improves airflow, reduces allergens, and helps your HVAC run more efficiently.

✅ Replace Furnace Filters Regularly
Dirty filters restrict airflow, reduce efficiency, and allow pollutants to bypass filtration. Change them every 1–3 months—or more often if you have pets or allergy sufferers at home.

✅ Consider Air Exchangers or Ventilation Upgrades
Energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs) bring in fresh outdoor air while maintaining energy efficiency, preventing stale indoor air from building up.
