This Bus Cleans Your City's Air While Doing Its Normal Route

One of the United Kingdom’s biggest bus and rail providers, the Go-Ahead Group, has launched a bus that makes the air cleaner. The bus features a filter that will remove ultra-fine particles from the air and trap them as the bus moves through the streets.

The Go-Ahead Group’s Chief Executive David Brown told the Huffington Post, “as the bus removes the ultrafine particles from the air as it travels along the route, it is helping solve the air quality problems of the city. This bus will clean the air on its route 1.7 times a year to a height of 10 metres - imagine the change we could make to air quality if all buses had this technology.”

The company launched the bus in Southampton, a city that according to the World Health Organization (WHO) is reaching the limit of unsafe air pollution. It is also one of five cities challenged by the government to come up with clean air solutions.

According to WHO, outdoor air pollution is the cause of over 4.2 million premature deaths each year. It can lead to many terrible diseases, and in areas with particularly high levels of air pollution, it is essential for governments to do everything in their power to decrease the levels of pollutions.

If the trial is successful, the filter could be added to Go-Ahead’s fleet of over 5,000 buses. Hopefully, companies across the world will follow Go-Ahead’s lead, and make the world a safer, healthier place to live in.
