Coffee waste air purifiers, gathering environmental data, sharing entertainment information


The Coffeelter takes in the polluted air and blows out the clean air. The most important part of the filter is coffee waste which stops PM2.5 particles. Coffeelters also gather the environmental data such as pollution, noise and sunlight level which can be sold to the data collecting companies. Another functionality of Coffeelter is providing information via wifi about the transport and entertainment in the city.
Coffeelters will be placed at the bus or tram stops or stations so in places where people are waiting nearby the traffic.
