The air pollution in London is serious. According to statistics, the number of people dying of air pollution is up to 9400 people every year. To highlight the severity of air pollution, a foot driver, Greg McNevin, designed a LED mask, hoping to raise public attention to the issue of air pollution.

The LED light-emitting mask is equipped with a sensor that operates with the AirBeam air monitoring system and connects to the AirCasting web site through Bluetooth, which can change the color in real time according to air pollution.

When the PM 2.5 values are between 0 and 12, that is, the air is in good quality, it is green; when the PM 2.5 rises to 12.5 to 35.4, it turns yellow; the PM2.5 is 35.5 to 55.4, the mask color will be orange; the PM2.5 exceeds 55.42 in red, reminding the user that the air quality is very unhealthy for all the people.
