The FusionAir Indoor Purification System leverages AIoT technology, and it uses big data and cloud computing to analyze risk indicators of indoor air pollution. This analysis is based on the Air Quality Index calculation rule set forth by the Environmental Protection Agency, as well as the Indoor Air Quality Standard (IAQ). It provides companies, hospitals, and healthcare institutions with tools to effectively manage indoor air quality, meets regulatory requirements, and improves indoor air quality management efficiency. In addition, FusionAir sensors can be installed in different locations across larger areas to display air quality data for each specific area on the management interface. Using AI data analysis, the system can identify air pollution hotspots and provide real-time purification.
