Project Overview

Human activities have increased global Greenhouse Gas and changed the hydrologic cycle, atmospheric circulation and temperature, leading to decrease in regional precipitation and the persistence of atmospheric stagnation. These have weakened the natural mechanism of removing PM2.5 particles in the air. The average PM2.5 levels in Taiwan now is two times more than WHO standards, inducing health concerns such as lung cancer or even death. Especially in the urban areas of Taiwan, due to the super high population and vehicle density, commuters are exposed to higher health risks when on the road daily. Seeing these problems, we looked into nature and asked, “How does nature actively collect micro particles?” Gaining inspiration from the mechanisms of salps, baleen whales, Aftrican violet’s trichomes leaves, REFISH was born. It is a PM2.5 collector that can be attached on any moving vehicle. By leveraging on the movement of vehicles to generate air flow into the collector module, REFISH can capture PM2.5 on the road without requiring electricity and motors to pump air like typical air purifiers. We hope with this low cost design, we can inspire commuters to shift into a more eco-friendly behavior and bring fresh air back to the road.
