We provide an intelligent air cleaning system with real-time monitor and remote control. The system is able to remove air pollution such as PM2.5, formaldehyde, VOC, and bacteria. In addition, the system does not only monitor air quality, but also transmit the air quality data wirelessly to the cloud database for further analysis. Based on the system, the countermeasures on promoting community environmental health can be established. As a result, we can breathe clean and fresh air everywhere.
