People living in metropolitan cities have to make their way to anywhere through traffic every day. In traffic areas like signals, narrow roads, bazars etc., there is a very high concentration of air pollutants due to automobile emissions. The air pollution these days is a serious environmental concern. Faster escape solutions are required than permanent over the time changing solutions. In some cities like Delhi the air quality index has reached to an irrefutable level. To avoid such problems, we came through an idea of an Outdoor Air Purifier in heavy traffic areas which would efficiently decrease pollutants emitted by automobiles. The Air Purifier consists of layers of HEPA and Activated Carbon filter. In the present work, the propeller fans mounted in the suction chamber sucks the atmospheric air into the chamber. Then air sucked by the fans pass through the layers of filters where it absorbs the particulate matter as well as VAC and other gaseous chemicals like NOx and SO2. Then the purified air is led to the atmosphere thereby decreasing the Air Quality Index. In addition, the alternate sources of energy like solar panel and wind turbine which are mounted on the unit, so that battery gets charged utilizing renewable energy such as solar and wind. The test results obtained were quite encouraging. There is a reduction of about 98% of CO and 95% HC emissions were revealed from the test results.
