One of the main features of London Air is the Nowcast Maps, which offer hourly updated air pollution maps of London. These maps provide users with an unparalleled view of air quality, allowing them to assess the pollution levels wherever they are in the city. Additionally, the extension allows users to scroll through the boroughs of London to find monitoring stations in their specific area.

London Air also offers a video guide with ten short videos that address commonly asked questions about air pollution and its impact on health. This feature provides users with valuable information and educates them about the effects of air pollution.

Furthermore, the extension includes an alert system that runs in the background and notifies users when pollution levels rise to Moderate or above. This feature ensures that users are always aware of any potential risks to their health.

London Air is a free extension and is available on the Chrome platform. It is a valuable tool for anyone living in or visiting London who wants to stay informed about air quality and make informed decisions to protect their health.
