While air pollution is usually worse around the sources of pollution, particles in the air can also travel surprisingly long distances and even across entire oceans. 

PM2.5 are particulate matter with a diameter of 2.5 microns of less. They come from both natural and human sources and can cause serious health problems. 

PM2.5 makes pre-existing health problems worse, increases the rate of illness progression and even leads to death. 

Data is power - it helps us reduce our air pollution exposure, helps our government determine better policies and helps us better manage our air quality. 

The AQI is an index divided into 6 categories: good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy and hazardous. 

Jakarta’s air quality has significantly worsened since 2017. The average Jakarta resident loses 4.8 years in life expectancy.

Air pollution causes problems in the placenta, premature birth and low birth weight. 

PM2.5 leads to allergies and asthma in kids, negatively affects intellectual development and reduces lung function in children. 

PM2.5 causes skin irritation, can worsen eczema, speeds up the aging process and can lead to skin cancer. 

Air pollution is the leading contributor to early mortality among the elderly. 

We breathe in more air when we’re exercising. It’s safest to exercise when the AQI color is green or yellow. 

Checking the AQI levels and taking the necessary precautions when the air quality is bad reduces our exposure to air pollution.
