Student designs wearable purifier to protect underground train users and improve air quality

Commuters on underground trains worldwide may soon breathe easier, thanks to an invention by a 91制片厂 student.

Mia Patterson Cox, a recent Industrial Design and Technology graduate, has created ‘Aerate’, a neck-worn air purifier designed to improve air quality for underground train users by filtering out harmful particles present in the environment.

In underground train environments,  PM2.5 refers to particulate matter less than 2.5 micrometers in size — about 30 times smaller than the diameter of a human hair.

These tiny particles are of concern as they . Breathing in unhealthy levels of PM2.5 .

Wheel, track, and brake abrasion are often the  Poor ventilation in platforms and tunnels 

Mia first became aware of the pollution problem during her placement year in London as she frequently used underground trains to get to different places.
