South Korea has real, often seasonal or localized pollution worth knowing about, especially if you have asthma or allergies.
Not typically needed for most travelers, but if you have asthma or allergies, it's a cheap, compact backup worth packing regardless of destination.
This reflects typical/baseline conditions, not a live reading — actual air quality varies day to day with weather, season, and wildfire or burning activity. If you have asthma, allergies, or another respiratory condition, check a real-time index (like IQAir or AirVisual) for your specific destination before travel, and pack a mask if the level is elevated.
