The SDU Air Purifier

In January 2018, students from the Service-Learning course PSY3103 Psychology of Human Performance and Technology visited families living in Sham Shui Po’s sub-divided flats to experience the challenges the families face each day.

The students identified poor air quality as a pressing challenge that influences tenants’ quality of life. By applying academic knowledge, simple technology and design thinking, students brainstormed and came up with the idea to design a low-cost air purifier after careful consideration of the households’ affordability and the setting of the tiny living environment. The prototypes were then tested in order to be further modified for enhancement.
