Wildfire smoke can originate far away, so insurers sometimes argue it’s “not attributable” to anyone. They also commonly claim your symptoms were caused by seasonal allergies, viruses, or a pre-existing condition.
In practice, disputes often turn on three locally important details:
- Timing around local routines: symptoms that started after commutes, outdoor time, or returning from errands during smoky days.
- Indoor air behavior in real homes: whether windows/doors were closed, whether fans/ventilation were used, and whether HVAC filtration was appropriate for heavy smoke.
- Medical consistency: what your clinician documented about triggers and whether your condition fit a smoke-related pattern.
