Loughborough graduate invents wearable air purifier for underground commuters

A recent Industrial Design and Technology graduate from Loughborough University has developed an innovative solution to combat air pollution in underground train systems. Mia Patterson Cox's invention, named "Aerate," is a neck-worn air purifier designed to create a clean bubble of breathable air around the user's face.



Aerate uses two high-speed fans and Spunbond Polypropylene filters to capture particles as small as 2.5 micrometers, including harmful iron-rich particles generated by wheel, track, and brake abrasion. The device aims to address the concerning levels of PM2.5 in underground environments, which often exceed World Health Organization limits.

Inspired by her experiences commuting in London, Cox developed Aerate to improve not only individual health but also the overall air quality for all passengers. The device is complemented by a smartphone app that provides real-time air quality data and filter replacement notifications.

While still in the prototype stage, Aerate has shown promising results in initial testing. Cox envisions her invention paving the way for safer underground travel experiences, potentially revolutionizing how commuters protect themselves from air pollution in urban transit systems.

As cities worldwide grapple with air quality issues in their underground networks, innovations like Aerate could play a crucial role in safeguarding public health and encouraging confidence in public transportation use.
