## What is Air Visual | PM2.5?

Inspect the Air Quality Index pollution around you based on your current location:
- the application contains statistics recorded and measured from weather censors from your nearby location
- those statistics are temperature, wind speed, humidity, PM2.5(particulate matter 2.5nm), PM10(particulate matter 10nm), SO2(Sulfur dioxide), NO2(Nitrogen dioxide), CO(Carbon monoxide) and O3(Ozone)
- PM2.5 is an air pollutant that is a concern for people's health when levels in air are high. The lower the number, the cleaner the weather. 
- PM2.5 can be considered into different levels. For the application, it shows six levels:
i) Good: AQI 0 ~ 50 
ii) Moderate: AQI 51 ~ 100
iii) Unhealthy for sensitive groups: AQI 101 ~ 150
iv) Unhealthy: AQI 151 ~ 200
v) Very Unhealthy: AQI 201 ~ 300
vi) Hazardous: Upper AQI 301
- It is very well recommended to wear a mask protecting PM2.5 when the air pollution around you is having AQI more than moderate level
