● Features of fine guard

1. International standards
We have broken down the steps based on the WHO recommendations for fine dust daily averages and US air quality recommendations.

2. Segmentation by target
The most important information, the fine dust phase, is divided into the sensitive (the elderly, the child, the pregnant woman, the respiratory system disease, etc.) and all the people and it is informed in five steps (Caution - Poor - Very Poor - Risk - Fatal).

3. Action guide
Each step-by-step action guide is provided with easy-to-see icons.

4. Ultra fine dust standard
