AQI 175

Unhealthy

About 4.64 cigarettes per 24h at this reading.

Outdoor dose rises fast in this band, especially if windows are open or activity is strenuous.

Cancel outdoor workouts, long walks, and open-window ventilation.
Use a quality mask outdoors and keep trips short.
Prioritize clean indoor air with HEPA filtration and closed windows.

Common planning patterns

Repeated exposure matters more than one isolated check when poor air is part of the weekly routine.
Rechecking later in the day is often as important as the first reading, especially when smoke or traffic patterns shift.
Indoor air becomes a bigger part of the decision once the city stays elevated for hours or overnight.

City planning checklist

  • Recheck before the longest or most exposed part of the day, not just once in the morning.
  • Use the linked scenario pages when the reading changes a commute, workout, or family routine.
  • Protect the indoor space that matters most first, especially sleeping or work-from-home rooms.
