Air Pollution


This shows how small PM 2.5 is (much smaller than the thickness of a human hair). Particles this small go straight through lungs and into blood stream, making them particularly damaging. Vogmask filters 99% of PM 1 (which is 2.5 times smaller than PM 2.5)

Sources of Air Pollution

Ever wondered WHERE all this air pollution comes from? Well, there are several different kinds. These pie charts show where each kind of air pollution comes from. Since this data was taken there has been an even greater shift towards coal burning around Beijing, which is one of the major pollutants in Beijing’s air (where Vogmask China are based)




Beijing is surrounded by a ring of coal-fired power stations. The Chinese economy continues to grow, and as people become wealthier they demand electricity-consuming goods such as washing machines and cookers etc. Along with increased car usage and more energy demands from industry, China has a long-term necessity to burn coal. It is one of the only easily available and affordable energy sources for the Chinese government.

As you can see from the diagram, Sanxi and Hebei have a big impact on Beijing’s air. So even if you plant tens of thousands of trees here in Beijing, it still may have a limited impact if neighbouring provinces do not also make significant changes.

This NASA satellite image shows the PM 2.5 levels across the globe. Air pollution is an issue globally, not just in China. It claims the lives of millions of people every year (including an estimated 1.2 million in China in 2010). It is vital that people protect themselves with high quality filtration facemasks as well as air purifiers inside the home.
