How to Improve Indoor Air Quality in Your South Bay Home
Practical, proven strategies for cleaner air — beyond just duct cleaning.
Indoor air is often 2 to 5 times more polluted than outdoor air, according to the EPA. Here's how to fix it.
Start with the source: clean your ducts every 3 to 5 years.
Upgrade your filter. MERV 11 is the sweet spot for most South Bay homes.
Add stand-alone HEPA purifiers in bedrooms.
Service your HVAC annually.
Control humidity — 40–50% is ideal.
Ventilate when cooking and showering.
Reduce indoor pollutants: VOCs from cleaners, candles, and synthetic fragrances.
