Improving Indoor Air Quality: A Complete Guide for South Bay Homes

Indoor air can be 2-5 times more polluted than outdoor air. Your HVAC system plays a crucial role in maintaining healthy air quality throughout your home.

Common Indoor Air Pollutants

• - **Dust and dust mites**
• Pet dander
• Pollen and allergens
• Mold spores
• Volatile organic compounds (VOCs)
• Bacteria and viruses

How Your HVAC System Helps

Your heating and cooling system constantly circulates air through filters, providing your first line of defense against pollutants.

Filter Selection Matters

Standard filters (MERV 1-4): Basic protection, mainly for the equipment Pleated filters (MERV 5-8): Better particle capture, good for most homes High-efficiency filters (MERV 9-12): Captures smaller particles including some allergens HEPA-type filters (MERV 13+): Maximum filtration, may require system modifications

Additional Air Quality Solutions

UV Air Purifiers Installed in your ductwork, UV lights neutralize bacteria, viruses, and mold that pass through.

Whole-House Air Purifiers Integrated with your HVAC system, these remove particles and odors throughout your home.

Dehumidifiers Controlling humidity (30-50%) prevents mold growth and reduces dust mite populations.

Ventilation Improvements Fresh air exchangers bring in outdoor air while maintaining energy efficiency.

South Bay Considerations
