DELHI, INDIA — An Indian architectural firm is proposing to build huge air purifying towers that will tackle air pollution in Delhi.<br /><br />Studio Symbiosis Architects says that its 60-meter-tall Aura towers will form an air cleaning system to protect city residents from pollution, including PM 2.5 particulate matter.<br /><br />According to DesignBoom, the structure's aerodynamic designs include spiraling contours that draw in polluted air and expel clean filtered air. <br /><br />The pressure differentials enables the tower to pull PM 2.5 particles into its internal filtering chamber. <br /><br />The architects claim the smaller iteration of the Aura tower with a height of 18 meters could clean 32 million cubic meters of air per day.<br /><br />The firm says the taller towers will form a protective ring around Delhi's city borders to keep pollution out, while the 18 meter towers will be built by pollution hot spots inside the city.<br /><br />Pollution detecting drones and air cleaner attachments for cars will also form an integrated system with the towers.
