The Growing Wildfire Challenge
Wildfire seasons have intensified across California, with smoke regularly affecting Bay Area air quality. Even fires hundreds of miles away can create hazardous conditions locally. Here's how to protect your family's indoor air quality.
Immediate Steps During Smoke Events
1. Keep Windows and Doors Closed
This seems obvious, but even small gaps let smoke in. Check weatherstripping and seal any obvious leaks.
2. Run Your HVAC System
Set your system to recirculate indoor air rather than bringing in fresh air. If you have an "outside air" damper, close it.
3. Upgrade Your Air Filter
During smoke events, upgrade to a MERV 13 or higher filter. These capture fine particulate matter (PM2.5) that causes health issues. Note: Check that your system can handle higher MERV ratings – some older systems need airflow modifications.
4. Use Portable Air Purifiers
HEPA air purifiers in bedrooms and main living areas provide an extra layer of protection.
Long-Term HVAC Solutions
Whole-House Air Filtration
A whole-house HEPA filtration system integrates with your ductwork to filter all circulated air. These systems:
- Remove 99.97% of particles 0.3 microns and larger
- Require less maintenance than portable units
- Don't take up floor space
- Can include activated carbon for odor removal
UV Air Purifiers
UV-C light systems installed in ductwork kill bacteria, viruses, and mold spores. While not specifically for smoke, they improve overall air quality.
ERV/HRV Systems
Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) bring in fresh air while filtering it and recovering energy. During smoke events, they can be set to recirculate only.
Duct Sealing
Leaky ducts in attics or crawlspaces can pull in smoky air. Professional duct sealing ensures all air comes through your filtration system.
Creating a Clean Air Room
If you can't upgrade your whole-house system, create one "clean room":
- Choose a room that can be sealed off
- Run a portable HEPA purifier sized for the space
- Seal gaps around doors with towels or draft stoppers
- Avoid activities that create particles (cooking, vacuuming)
Filter Recommendations
Post-Fire Season Maintenance
After smoke season:
- Replace all filters
- Schedule duct cleaning if exposure was heavy
- Have your system inspected for any smoke residue
- Consider permanent upgrades before next season
Health Considerations
Smoke exposure is particularly dangerous for:
- Children and elderly
- People with asthma or respiratory conditions
- Heart disease patients
- Pregnant women
If you or family members are in high-risk categories, investing in air quality improvements provides year-round health benefits, not just during fires.
