Merriam is part of a busy corridor where people are often exposed in small windows throughout the day: driving, commuting, and spending time in buildings with HVAC cycling. Unlike a single “one-time” event, smoke exposure in everyday life can be intermittent—morning air might be clearer, but afternoons near major roadways or during heavier smoke periods can be worse.
That pattern matters legally because insurers often argue your symptoms were caused by something other than wildfire smoke. The stronger approach is to anchor your case to a timeline that matches how exposure likely occurred for you in Merriam’s daily routine.
