"Is the air around me really okay?"

Miseyang is a smart air quality information app that delivers data from the nearest monitoring station based on the latest real-time data from the Korea Environment Corporation (Air Korea), reinterpreting it according to strict WHO standards.

Please use version 0.1.5.1 or higher, which incorporates the latest monitoring stations for 2026.

■ Key Features of Miseyang

1. Application of Strict WHO Standards

We apply WHO (World Health Organization) recommended standards, which are much stricter than general domestic standards. Check fine dust, ultrafine dust, and ozone levels at a glance using safer standards.

2. Automatic Connection to Nearest Monitoring Station

We display data from the nearest monitoring station, not just simple administrative district information. Even during station maintenance, we dynamically locate nearby alternative stations to provide uninterrupted information.

3. Intuitive Air Quality Index (CAI) at a Glance

Based on the Comprehensive Air Quality Index (CAI), Miseyang intuitively informs you of current air quality through its unique, friendly characters and colors. You can judge the situation immediately just by the colors, even without knowing the complex numerical values!

Utilizing credible data from the Korea Environment Corporation, we provide fine dust forecast information for today and tomorrow. Plan your outings with Misaeyang.
