Purio is an air purifier designed for stroller users, catering to both parents and children. Given the recent elevated levels of fine dust in Korea, it has become a growing concern, particularly for infants with developing lungs who are more vulnerable. The project was initiated to alleviate parental concerns regarding fine dust exposure when taking their children outdoors. Additionally, it addresses the desire of parents to keep an eye on their children’s activities while they’re in the stroller.
