Unlike existing purifiers, the Active Action air purifier uses a motion sensor to detect main living spaces and blind spots, and its “head” rotates in all directions while efficiently cleaning the air. Its IoT technology analyzes contaminated areas to clean them beforehand and provide various data about air quality through a smartphone app. One problem many air purifiers have is that they sit quietly in corners and it can be hard to tell if they are actually cleaning. To solve this problem, we designed the Active Action air purifier with a round cleaning area on a rotating head so users can see that the purifier is working hard.
