San Francisco Homeowners Fight Back Against Wildfire Smoke and Urban Air Pollution with Smart HVAC Solutions

San Francisco residents face a unique double challenge when it comes to indoor air quality. The city experiences severe wildfire smoke events, with Air Quality Index levels reaching over 150 “unhealthy” for 12 straight days, peaking at 250.7 during events like the 2018 Camp Fire. Combined with ongoing urban pollution from traffic and industry, maintaining clean indoor air has become essential for protecting family health.

San Francisco is particularly vulnerable to extreme heat events and wildfire smoke events because buildings, infrastructure, services, and communities were not designed for extreme temperatures and poor air quality. However, homeowners can take proactive steps to create healthier indoor environments through strategic HVAC upgrades and proper system management.

Understanding the Air Quality Challenge

While San Francisco is unlikely to have wildfires within city boundaries, the city expects to be affected by wildfire smoke, especially during fall wildfire smoke events that coincide with the Diablo Winds. The primary pollutant threatening health is particulate matter, with wildfire smoke containing fine (PM2.5) and ultrafine particles that penetrate deeply into the lungs.

Exposure to wildfire smoke and air pollution varies from neighborhood to neighborhood and building to building, with factors including access to ventilation affecting exposure levels. This makes proper HVAC system configuration crucial for San Francisco homeowners.

Essential HVAC Solutions for Smoke Protection

High-Efficiency Filtration Systems

Upgrading to HVAC filters with a MERV 13 rating or higher can significantly improve filtration, with extra filters kept on hand as they may need changing every few weeks or days during smoke events. These filters can trap smaller particles, including PM2.5, reducing indoor smoke levels effectively.

For central HVAC systems, installing high-efficiency filters (MERV 13 or higher) can increase air filtration throughout the home. For enhanced protection, HEPA filters can capture up to 99.97% of particles as small as 0.3 microns.

System Operation During Smoke Events

If your HVAC system has a fresh air intake, learn how to close it or turn the system to “recirculate” mode during wildfire events. Setting HVAC systems to recirculate indoor air rather than drawing in outdoor air minimizes the introduction of smoky air from outside.

Once filters are replaced and fresh air intakes closed, run your air conditioning system at maximum efficiency without turning it off while wildfire smoke is present. Running the HVAC system in recirculation mode helps filter indoor air without bringing in polluted outdoor air.

Supplemental Air Purification Solutions

Portable air purifiers equipped with high-quality HEPA filters are practical solutions for enhancing air quality in specific rooms, with Clean Air Delivery Rate (CADR) ratings matching room size for optimal performance and strategic placement in frequently used areas.

Creating a clean room—a space set up to keep smoke and particle levels as low as possible—can contain a portable air cleaner that makes the air cleaner than the rest of the home. When Air Quality Index indicates smoke levels are unhealthy, spending time in a clean room at home can help reduce exposure to smoke while staying indoors.
