La Puente is a community of commuters and mixed residential settings—single-family homes, multi-unit housing, schools, and businesses with HVAC systems. During wildfire season, that mix matters.
Smoke can enter through:
- Outdoor air intake on HVAC systems when filtration is inadequate
- Open windows/doors during hot days when people try to stay cool
- Workplace conditions where employees are required to be outside or near loading areas
- School and childcare ventilation where schedules and guidance may lag behind worsening air quality
Even when smoke originates far away, La Puente can still experience spikes in particulate pollution that aggravate lung and heart conditions. If your symptoms intensified during your commute, at work, or at a local facility, the timeline becomes essential.
