Los Altos is a suburban community with a heavy residential footprint and many homes that rely on closed windows, HVAC filtration, and sealed ductwork. During wildfire smoke episodes, small differences in indoor air handling can change how severely people are affected.
Common Los Altos scenarios we see include:
- HVAC not adjusted for smoke: Filters not changed on schedule, airflow settings left in “recirculate,” or systems running without adequate filtration.
- Shared indoor spaces: Dentists’ offices, gyms, daycare, and co-working areas where multiple people report symptoms after the same smoke period.
- Commuter exposure patterns: Symptoms that start after returning from work or errands when smoke levels spike along Bay Area routes.
- Home air quality differences: One household member improves with cleaner-air strategies while another worsens—often reflecting differences in filtration, room use, or pre-existing conditions.
Because Los Altos residents spend a large portion of the day indoors, your claim often turns on indoor exposure details as much as outdoor smoke.
