Contributing or Supporting this Project

The World Air Quality project might look like one of those big projects coming from organizations like the UN, ADB or WRI, but it is actually just a small team behind it.

Yet, despite our extensive outreach, our project has never received any financial support from such organizations, wether they are NGOs or governments.

The income comes from online advertising, as well as our GAIA air quality monitoring stations, but it is just enough to pay for the cloud infrastructure.

However, we are working on getting funding for the recruitment of a team dedicated to supporting and enhancing the air quality data platform.

If you would like to help, either by becoming one of our team member, either by providing financial support, or both, then contact us via this page: aqicn.org/contribute

Interested in monitoring your own Air Quality?

The GAIA air quality monitor uses laser particle sensors to measure in real-time PM2.5 and PM10 particle pollution, which is one of the most harmful air pollutants.

It is very easy to set up: It only requires a WIFI access point and a USB compatible power supply. Once connected, your real time air pollution levels are instantaneously available in on our maps.

The station comes together with 10-meter water-proof power cables, a power supply, mounting equipment and an optional solar panel.

About the Air Quality Levels

AQI Air Pollution Level Health Implications Cautionary Statement (for PM2.5)
0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk None
51 -100 Moderate Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
101-150 Unhealthy for Sensitive Groups Members of sensitive groups may experience health effects. The general public is not likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
151-200 Unhealthy Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
201-300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
300+ Hazardous Health alert: everyone may experience more serious health effects Everyone should avoid all outdoor exertion
